Major Shadow of the Erdtree spoilers follow. Messmer the Impaler is a mandatory remembrance boss in the upper levels of Shadow Keep. You fight him in Messmer’s Dark Chamber, where the battle changes from Messmer the Impaler to Base Serpent Messmer at roughly half health.
This guide covers the route to Messmer, both phases, damage types, summon choices, rewards, and the lore behind Marika’s hidden son, the Hornsent Crusade, Messmerfire, and the Base Serpent. The combat information is presented for the latest official patch record identified in the supplied research, Version 1.16.1; its notes do not list a Messmer-specific balance adjustment. See the official Version 1.16.1 patch notes for the patch context.
Before you can reach Messmer
Messmer is part of Elden Ring: Shadow of the Erdtree, not the base game. To enter the Realm of Shadow, you must first:
- Defeat Starscourge Radahn.
- Defeat Mohg, Lord of Blood in Mohgwyn Palace.
- Return to the cocoon in Mohg’s arena.
- Speak with Needle Knight Leda if necessary.
- Interact with Miquella’s withered arm to enter the expansion.
These are DLC-entry requirements rather than separate requirements for Messmer. Once you are in the Realm of Shadow and have progressed to Shadow Keep, there is no character-level gate preventing you from reaching him.

Do not enter Messmer’s chamber before checking NPC quests
Messmer’s boss arena contains quest-dependent NPC summon signs, and some dialogue and event triggers around the Hornsent and Needle Knight Leda can become unavailable or advance at uncertain points. Sources disagree about whether particular steps are locked by entering the arena, starting the fight, or defeating Messmer.
The safest rule is simple: before opening the Dark Chamber door, return to relevant NPCs and exhaust the dialogue and quest steps you want. In particular, check:
- Hornsent and Hornsent Grandam, including the relevant Grandam dialogue.
- Needle Knight Leda and any Hornsent-versus-Leda decision.
- Count Ymir and Jolan, if you are following the Finger Ruins quest.
Defeating Messmer affects later Hornsent Grandam dialogue and rewards. The larger DLC-wide quest lockout is generally associated with burning the Sealing Tree later, but that does not make it safe to assume every individual event remains available until Messmer dies. The Shadow of the Erdtree walkthrough and the Grandam quest reference document the relevant progression warnings.
Preparation: level, Scadutree Blessing, and defenses
There is no required level
Community guides commonly suggest approaching Messmer around level 150–170, sometimes naming level 158 specifically. Treat that as a comfort recommendation, not a requirement. Your Scadutree Blessing, Vigor, weapon upgrade, damage matchup, and familiarity with Messmer’s timing matter more than one character-level number.
Scadutree Blessings increase your attack power and damage negation in the Realm of Shadow. Revered Spirit Ash Blessings improve the performance of spirit ashes. Both systems are separate from ordinary levels and equipment, so collecting more Scadutree Fragments can make a larger practical difference than spending several additional character levels. Around Blessing 10 is a frequently cited community target, but it is not a hard threshold.
Survivability checklist
- Consider 50–60 Vigor if Messmer’s grab or a complete combo is killing you outright.
- Use the Flamedrake Talisman +3, Flame, Protect Me, or a Fireproof Dried Liver if fire damage is the main problem.
- Dragoncrest Greatshield Talisman can help with the physical portion of his spear attacks.
- Wear armor with good physical and fire negation, but do not sacrifice all poise, stamina, or damage merely to maximize fire resistance.
- Upgrade your weapon or staff to an appropriate level before attempting repeated runs.
Fire mitigation is useful, but it does not solve the fight. Many attacks combine physical damage, fire, long reach, delayed hitboxes, and follow-up strikes. You still need to roll through the correct attack and avoid trading.
How to reach Messmer in Shadow Keep
Messmer is in the upper portion of the Specimen Storehouse, at the end of Shadow Keep’s vertical route. The named Sites of Grace make the route easier to follow:
- Enter Shadow Keep and fight or pass the initial interior enemies.
- Reach Storehouse, First Floor.
- Work upward through the Storehouse’s shelves, stairs, ladders, and connecting platforms.
- Use the large suspended statue and the rotating-statue mechanism to reach the upper route.
- Rest at Storehouse, Fourth Floor as you progress.
- Continue to Storehouse, Seventh Floor.
- Take the route outside, pass the Fire Knight, and activate Dark Chamber Entrance.
- Open the chamber door to begin the fight with Messmer.
The Storehouse’s vertical layout makes it easy to lose your position. If you are at First Floor, think upward rather than toward a separate wing; Fourth Floor is the useful midpoint, and Seventh Floor leads to the exterior approach. The PowerPyx DLC walkthrough and Push Square’s Messmer route guide provide visual route references.
Messmer’s boss data

| Location | Messmer’s Dark Chamber, Shadow Keep |
| Boss type | Mandatory remembrance boss and demigod |
| Phase two | Base Serpent Messmer |

The HP and resistance figures are base-cycle database values. They should not be treated as universal numbers for New Game Plus cycles, multiplayer scaling, or a later regulation file. Resistance tables also differ in some phase-two details, so use the table as build guidance rather than a guarantee of exact in-game damage.
Public data for Messmer is collected in the Gamer Guides boss database and the Eldenpedia Messmer entry.
How to beat Messmer the Impaler
The opening attack
Messmer can attack almost immediately after you enter. This matters because his NPC summon signs are inside the arena rather than safely outside the fog wall. If you run directly toward a sign without dealing with the opening, you can die before the summon is activated.
Free tools Windows power users keep installed
One-click scans. No signup required.
On your first attempts, enter expecting an attack, evade it, and only then move toward an NPC sign or summon your Spirit Ash. Once you recognize the opening, you can summon more efficiently, but never assume the arena gives you a free setup period.
Positioning: roll through, not endlessly away
Messmer’s spear has deceptively long reach, and many of his strings branch into follow-up attacks. Rolling backward can leave you inside the next thrust or sweep. In most close-range exchanges, rolling into or across the attack is safer than repeatedly retreating.

- Stay close enough that a successful roll places you beside or behind him.

- Keep your health near full before risky exchanges. The grab can kill characters at ordinary health totals.
Phase one: Messmer the Impaler
In the first phase, Messmer fights as a fast, highly mobile spear-wielder. His moveset includes rapid thrusts, sweeping strings, aerial lunges, flaming spear throws, fire bursts, and a lethal-looking grab that should never be traded.
His branching combos are designed to punish panic rolling and button-mashing. The reliable rhythm is: roll through the attack, take one or two hits, then disengage before the next branch. Heavy weapons can still stagger him, but only commit to jumping heavies, charged attacks, or guard counters when you have identified a genuine recovery window.

|---|---|
| Basic spear string | Roll through the sequence, especially the final hit, then take one or two attacks before resetting. |
| Aerial flaming lunge | Roll as the spear descends rather than as Messmer first rises. Punish his landing if you are in range. |
| Fire burst around his body | Back away during the activation and explosion. Re-enter once the burst has finished. |
| Flaming spear throw | Side-roll the projectile or close distance after it passes. Do not assume the throw is the end of his turn if you are too far away. |
| Grab or impalement attempt | Roll later than your first instinct suggests and never trade. A failed grab gives you a short opportunity; a successful one can end the attempt. |
The phase transition
At approximately half health, a cutscene plays. Messmer removes the restraint associated with his eye and releases the power of the Base Serpent. His health bar does not reset, so damage dealt in phase one carries over.
Do not begin a long attack animation as he approaches the transition threshold. The cutscene can interrupt your rhythm and leave you badly positioned for the start of phase two. Treat the transition as a reset point: recover your camera, stamina, and spacing before attacking again.
Phase two: Base Serpent Messmer
Phase two retains some of the spear attacks but adds serpent-form attacks and more abrupt movement. Messmer can launch a large serpent-shaped fireball, dive or bite repeatedly, send multiple serpents toward you, emerge attacks from the ground or red pools, and combine aerial spear barrages with serpent assaults.
The most important phase-two rule is do not attack during the transformation itself just because Messmer appears vulnerable. Wait for the serpent sequence to end, then punish the recovery or the moment he returns to humanoid form.
| Phase-two pattern | Response and punish |
|---|---|
| Serpent dive or bite | Roll sideways or toward the attack’s endpoint. Attack after the serpent completes its recovery, not during the dive. |
| Triple-serpent bite | Preserve stamina for all three impacts. The safe punish comes after the final slam. |
| Serpents from the ground or red pools | Move first when the arena signals the emergence. Reposition rather than trying to finish a slow attack. |
| Large serpent-form fireball | Keep moving and evade the projectile or its area effect. Close in only once the attack has clearly ended. |
| Aerial spear barrage | Stay mobile and wait for the final slam or landing. Chasing him into the air commonly produces a mistimed counterattack. |
| Human-to-serpent transition | Watch for the end of the sequence and punish the recovery as Messmer returns to a more conventional stance. |
Healing windows
Healing at long range is not automatically safe. Messmer’s mobility and spear throws can punish passive retreat. The better moments are after a completed combo, after the final impact of a serpent sequence, or while he is recovering from a clearly missed aerial attack. Create distance only after his attack has committed, then drink while keeping enough stamina to evade a projectile.
Weaknesses and build advice
Damage types
- Fire: A poor primary plan. Messmer has high listed Fire negation, so fire-only weapons, spells, and buffs lose much of their efficiency.
- Slash: A strong physical option according to public resistance tables. This is an inference from the listed resistance values, not an official developer-designated weakness.
- Magic and Lightning: Neither is listed as heavily resisted in the same way as Fire, but fast casts work better than slow channeling because Messmer constantly closes distance.
- Holy: Use cautiously. Public tables report high first-phase Holy resistance, while phase-two values differ between databases.
- Bleed and Frostbite: Both are practical if your weapon applies buildup quickly enough. Messmer’s speed makes status application difficult for slow or overly defensive setups, so these are useful tools rather than an automatic easy mode.
- Sleep, Madness, and Death Blight: Do not build around them; Messmer is listed as immune.
Calling Messmer simply “weak to magic” is too broad. The practical conclusion is to choose a damage type he does not heavily resist and pair it with attacks that have short recovery. A fast physical, Lightning, Magic, Bleed, or Frost setup may work well, but the best choice depends on how reliably you can hit him without being caught in the next string.
Melee builds
Slash weapons and fast status weapons are broadly practical. Stay near Messmer, roll through the spear, and punish the final hit of a string. Jumping heavies, charged heavies, and guard counters can deal excellent stance damage, but only use them after a confirmed opening. A charged attack that begins during a combo is usually a liability.
Do not interpret “aggressive” as constant attacking. The effective melee pattern is controlled aggression: evade, land one or two hits, then prepare for the next branch.
Recommended Free Tools
Bleed and Frost builds
Bleed and Frostbite can shorten the fight if you apply buildup consistently. Favor weapons and attacks with quick recovery rather than a slow attack that applies more buildup on paper. If you are spending most of the fight running away, a theoretically optimal status weapon may perform worse than a lower-damage weapon that lets you safely land repeated hits.
Intelligence, Faith, and ranged builds
Use fast projectiles and spells that leave enough stamina for the next dodge. Long channeling spells such as Comet Azur or Rock Sling are difficult to use safely unless a Spirit Ash, NPC, stagger, or terrain position reliably holds Messmer’s attention.
Fire spells are thematically appropriate but inefficient against his high Fire resistance. Fast Magic, Lightning, physical projectiles, and status application are generally more practical than a Fire-only spell loadout. The same principle applies to bows and other ranged weapons: fire after a committed attack and keep moving rather than standing still for maximum theoretical damage.
Shield users
A shield can help you learn the timing, but many of Messmer’s attacks include fire damage. Blocking may therefore prevent a full hit while still allowing chip damage and draining stamina. Pair a shield with strong fire mitigation and enough stamina, and do not remain planted through a long string. Rolling through selected attacks is often safer than trying to block everything.

Spirit Ashes, NPCs, and co-op
A Spirit Ash is the simplest way to create openings for a ranged build or to give a melee character time to heal. An NPC summon can also divide Messmer’s attention, but each additional helper affects the fight’s pacing and, in ordinary multiplayer, boss scaling must be considered separately.
Solo play preserves the duel’s intended rhythm and makes Messmer’s targeting more predictable. Summons are not a wrong way to fight him; they are a way to trade some predictability and potentially higher boss durability for opportunities to attack.
Hornsent and Jolan summons
Hornsent
Hornsent can appear as a summon if you progress his quest and side with him rather than allowing Needle Knight Leda to eliminate him. His sign appears inside Messmer’s arena, generally near the entrance. If he participates in the victory, his quest continues toward later events in Rauh.
Because Hornsent’s sign is inside the room, deal with Messmer’s opening attack before attempting to activate it. The Hornsent quest guide from Game8 and GameSpot’s Hornsent guide cover his quest and summon conditions.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesJolan
Jolan can become available through Count Ymir’s quest. Public guides place her sign on the opposite side of the arena from Hornsent. Her exact availability requirements are described inconsistently, so the conservative approach is to progress Ymir and Jolan through the early Finger Ruins sequence, exhaust their dialogue, and check the arena before concluding that the sign is unavailable.
See the Jolan reference for her character information and quest context.
Can both NPCs be summoned?
Coverage and player reports conflict. Some guides say both signs can appear and imply both helpers can be used, while other walkthroughs report that only one of Hornsent or Jolan can actually be selected for the fight.
Do not plan on definitely summoning both. Two quest-dependent signs may be visible, but you should expect to choose one NPC helper. This avoids losing a fight or quest opportunity because a guide promised a combination that your quest state does not permit.
Messmer’s rewards
Remembrance of the Impaler
Defeating Messmer awards the Remembrance of the Impaler. You can consume it for 40,000 runes, or take it to Finger Reader Enia in Roundtable Hold to exchange it for one of two boss rewards:
- Spear of the Impaler
- Messmer’s Orb
Choose according to your build rather than consuming the Remembrance automatically. Its item details are recorded in the Remembrance of the Impaler reference.
Spear of the Impaler
The Spear of the Impaler is a Great Spear with Standard/Pierce damage and the unique skill Messmer’s Assault. Its listed requirements are:
- 14 Strength
- 35 Dexterity
- 18 Faith
Its listed base attack is 85 Physical and 102 Fire. Strong attacks can throw the spear, and charged throws produce flame on impact. It uses Somber Smithing Stones. Despite its fire component, the weapon is not a recommendation for the Messmer fight itself because the boss has high Fire resistance; its value is as a post-boss weapon for a suitable Dexterity/Faith build. See the Spear of the Impaler data page for its full details.

Messmer’s Kindling and the next region
Messmer’s Kindling is a key item, not a consumable that you should sell or use from your inventory. It is required at the Sealing Tree near the Church of the Bud in the Ancient Ruins of Rauh. Using it to burn the tree removes the barrier to Enir-Ilim, the DLC’s final region and the route to its concluding sequence.
Before burning the Sealing Tree, finish any remaining NPC conversations, quest rewards, and summon-related steps you want. Burning it is the broader point of no return for many Shadow of the Erdtree questlines. The Messmer’s Kindling reference and DLC walkthrough cover the post-Messmer progression.

Marika, the Land of Shadow, and the hidden war
Bandai Namco’s official DLC framing describes the Land of Shadow as a region obscured by the Erdtree and the place where Marika first set foot. It was purged in an unsung battle, while Messmer’s flame set the land ablaze. Miquella later departed for this realm after divesting himself of his flesh, strength, lineage, and all things Golden.

Read the official Shadow of the Erdtree story page and DLC announcement for the first-party description of the Land of Shadow and Miquella’s journey.
Who is Messmer?
Messmer is a demigod child of Queen Marika. The game does not provide a complete, explicit family tree or settle every question about his birth order and parentage. What the item descriptions and dialogue do establish is that he was one of Marika’s offspring, that he ruled from Shadow Keep, and that he led the Crusade against the Hornsent.
His title, the Impaler, describes both his signature spear and his role as the executioner and public face of the campaign. Messmer’s armor and boss-room dialogue frame him as someone who intentionally made himself into a figure of fear. The apparent purpose was to make the Hornsent direct their hatred at him rather than at Marika.
Recommended Free Tools
This does not make him an impartial or reluctant observer. He led an exterminatory campaign, but the story also presents him as a weapon given a role and then concealed when the political cost or the danger within him became unacceptable.
The Hornsent perspective
The Erdtree-aligned account is only one side of the Crusade. Hornsent dialogue describes the Erdtree as the enemy of their people and Messmer as the person responsible for the flames. The survivors speak in terms of betrayal, extermination, and vengeance, not a legitimate cleansing carried out by a benevolent order.
Hornsent’s post-Messmer dialogue is especially important. Killing Messmer does not resolve the conflict for him. It opens the way toward revenge against Marika, her offspring, and Erdtree society. That is why Messmer’s death is a turning point in the Hornsent story rather than a simple victory over the DLC’s villain.
The Hornsent dialogue archive preserves this perspective, while the Crusade overview collects the associated item and story references.

Messmerfire and the Base Serpent
Messmer’s power is not ordinary flame. His dark-red, serpentine fire is referred to as Messmerfire, Messmer’s Flame, or, through its key-item connection, Messmer’s Kindling. The fire is central to both his identity and the destruction carried out during the Crusade.
At the same time, Messmer is not simply a fire-user who happens to adopt a snake-shaped attack. A wicked or malevolent serpent exists within him. Marika sealed that power behind one of Messmer’s eyes using a seal of grace. The first phase shows the controlled, weaponized figure Marika created; the transition cutscene shows him destroying the restraint and releasing the Base Serpent’s power.
The Helm’s description also connects Messmer with winged serpents as constant companions before and after the seal was broken. Taken together, the evidence presents a conflict between Messmer’s imposed identity as Marika’s weapon, his innate vision of flame, and the serpentine power he was forced to conceal.
The second phase is therefore a character revelation expressed through mechanics. Base Serpent Messmer is not merely a stronger health bar; it is Messmer rejecting, or losing control of, the seal that kept his hidden nature contained.
The game does not establish that the Base Serpent is an Outer God. That interpretation remains speculation unless future material provides clearer evidence.
Was Messmer abandoned by Marika?
“Abandoned” is a strong interpretive summary rather than a complete direct statement. The item descriptions support the following sequence: Marika ordered or authorized the Crusade, Messmer became its public face, and Marika eventually hid him and the campaign away in the Realm of Shadow because of the serpent within him and the need to conceal what had happened.
Messmer remained in Shadow Keep, continuing the war and waiting for a summons or release that never came. The emotional conclusion—that Marika abandoned her son after using him—is strongly supported by the circumstances, but the game leaves some of Marika’s precise motives and chronology for the player to infer.
Is Messmer Melina’s brother?
Probably, but it is not explicitly confirmed by name. Messmer’s Kindling refers to his younger sister without identifying her. Melina is the obvious candidate because she is associated with Marika, kindling, and a vision of fire. Both characters also connect fire with the burning of a major tree-like barrier.
Those parallels make Messmer and Melina siblings one of the strongest interpretations in the DLC. However, the item description does not say “Melina,” and the game does not provide a direct family-tree statement confirming it. The accurate wording is that Messmer is strongly inferred to be Melina’s brother, not that the relationship is fully stated canon.
The same caution applies to claims that Messmer’s flame and Melina’s flame are literally identical. The thematic and narrative parallels are clear; the exact relationship between their powers is not directly established.
What is confirmed, inferred, and unresolved?
| Category | What the evidence supports |
|---|---|
| Confirmed | Messmer is a demigod child of Marika, ruled from Shadow Keep, led the Crusade against the Hornsent, wielded Messmerfire, contained a serpent sealed behind his eye, and leaves Messmer’s Kindling when defeated. |
| Strong inference | The unnamed younger sister in Messmer’s Kindling is Melina. Messmer was effectively abandoned after Marika hid him and the Crusade in the Realm of Shadow. |
| Unresolved | Messmer’s exact birth order, the complete identity and nature of the Base Serpent, the precise chronology of the Crusade, and the full extent of Marika’s motives. |
Keeping those categories separate matters in Elden Ring. The game deliberately provides item descriptions, visual parallels, and contradictory perspectives rather than a complete historical record. Messmer’s story is clearest when the Hornsent account and the Erdtree account are read together rather than treating either side’s propaganda as the whole truth.
If you keep dying: quick troubleshooting
- You die while trying to summon: Expect an immediate attack, evade it, then activate the sign. The summon signs are inside the arena.
- You are killed by one combo: Raise Vigor toward 50–60, improve Scadutree Blessing, and add physical or fire mitigation before changing your entire build.
- Your fire build deals disappointing damage: Switch away from Fire-focused attacks. Messmer has high Fire resistance.
- You cannot find a punish window: Stop attacking after individual swings. Roll through the complete string and punish the final recovery.
- Phase two feels impossible: Do not chase serpent transformations. Preserve stamina through the full dive or triple-bite sequence and attack only after the final recovery.
- Your status build is not triggering: Use faster attacks and shorter commitments. High theoretical buildup is irrelevant if Messmer interrupts every attempt.
- Hornsent or Jolan’s sign is missing: Recheck their quest progression and dialogue. Their availability depends on quest state, and Jolan’s requirements are reported inconsistently.
- You are unsure whether to proceed after the victory: Speak to NPCs and collect desired rewards before burning the Sealing Tree, which is the broader DLC progression lockout.
Frequently Asked Questions
Is Messmer the Impaler optional in Shadow of the Erdtree?
No. Messmer is a mandatory remembrance boss for the DLC’s main progression. His Kindling is required to burn the Sealing Tree and open Enir-Ilim, although you can explore other parts of the DLC before fighting him.

What is Messmer weak to?
Do not rely on Fire damage, since Messmer has high Fire resistance. Public resistance tables make Slash a practical physical choice, while Bleed, Frostbite, Poison, and Scarlet Rot can work if applied consistently. Fast Magic or Lightning attacks are also viable, but there is no single universal weakness.
Can I summon both Hornsent and Jolan for Messmer?
Both quest-dependent signs may be visible, but guides and player reports conflict about whether both can actually be selected. Expect to choose one NPC helper rather than planning on using both.
Is Messmer confirmed to be Melina’s brother?
No. Messmer’s Kindling mentions a younger sister without naming her. Melina is the strongest candidate because of their shared connection to Marika, fire, and kindling, but the relationship remains a strong inference rather than an explicit confirmation.
The Bottom Line
Messmer is a mandatory Shadow of the Erdtree boss at the top of Shadow Keep. Prepare with Scadutree Blessings, enough Vigor to survive his grab and combos, and a fast damage plan that does not depend on Fire. Roll through his spear strings, wait out the serpent attacks in phase two, and punish recoveries rather than transformations. Before entering the Dark Chamber, finish the NPC quest steps you care about; after victory, choose the Remembrance reward carefully and save the Sealing Tree for after your remaining DLC conversations and rewards.
