The fastest farm depends on what you are leveling: the Season 4 guide from AllThingsHow recommends Kuiper Mine Blockade for Descendant XP and Albion Resource Defense for weapon proficiency. Choose Hard 400% Infiltration Operations when you also want materials; use Karel’s Mothership only if you value leveling both tracks in one run over speed. The times below are that guide’s estimates, not guaranteed results.
Best XP farms at a glance
| Activity | Best for | Reported time or trade-off |
|---|---|---|
| Kuiper Mine Blockade | Descendant XP | About 6–7 minutes from level 1 to 40 with an active booster and XP-multiplier equipment, according to AllThingsHow’s September 15, 2026 guide. It says the activity does not grant weapon XP. |
| Albion Resource Defense | Weapon proficiency | About 6–7 minutes to max all three equipped weapons under the guide’s reported Season 4 equal-sharing rule. The guide notes that loot is limited. |
| Hard Infiltration Operation at 400% | XP plus upgrade and crafting materials | Expect multiple runs to cap a Descendant and weapons. The guide says 400% difficulty rotates daily and is available for two missions at a time. |
| Sigma Sector Dropoff Operation | Short runs and Arche XP | The guide reports 2–3 minutes and 1,500 Arche XP per run; it also identifies endgame loot as a reason to play. |
| Karel’s Mothership on Normal | Leveling a Descendant and weapons together | The guide reports runs of 30 minutes or more and describes the content as difficult. Boss strength can make this a poor choice if your build is not ready. |
These are third-party estimates from AllThingsHow’s September 15, 2026 Season 4 guide, not official Nexon XP rates or independently verified completion times. Actual results can vary with boosters, equipment, build strength, mission availability, and group execution. Read the guide.
Which farm should you choose?
For Descendant levels
Start with Kuiper Mine Blockade if your goal is to level a Descendant quickly. The guide’s 6–7-minute estimate assumes a run from level 1 to 40 with an active booster and XP-multiplier equipment. It recommends an area-clear build to keep the activity moving; do not use it expecting weapon XP.
For weapon proficiency
Use Albion Resource Defense and equip the weapons you want to level. AllThingsHow reports that a Season 4 change gives equal progress to all three equipped weapons, even when a weapon is not currently in your hands. Its 6–7-minute estimate is for maxing all three equipped weapons, and the guide cautions that loot is limited.

For XP and materials
Choose a Hard Infiltration Operation at 400% when crafting or upgrade materials matter alongside leveling. The guide says the 400% option rotates daily and appears on two missions at a time, so check the available mission rotation before planning a farm. It takes multiple runs to cap a Descendant and weapons.
For short runs and Arche XP
Sigma Sector Dropoff Operation is the guide’s short-run alternative: it reports 2–3 minutes per run and 1,500 Arche XP. That makes it worth considering when Arche XP or endgame loot is useful to you, rather than assuming it is the best route for every leveling track.
To level both tracks in one activity
Karel’s Mothership on Normal can level a Descendant and weapons together, but the guide reports runs of 30 minutes or more and calls the content difficult. It is a better fit when you can handle the bosses and prefer combined progression to the fastest possible run.
How leveling works, and why an item may return to level 1
Nexon Support states that “Descendants and Weapon Proficiency can be leveled up to Lv. 40.” At level 40, assigning a module socket type resets the relevant Descendant or weapon to level 1. That reset is tied to socket customization, so a level-1 item after socket assignment is not necessarily a new or lost item. See Nexon Support’s explanation of the level cap and socket assignment.

If you are new to the game
Keep progressing through quests and missions while improving your equipment; the specialized farms are not a substitute for unlocking content. Nexon’s Game Guide describes mission progression and equipment growth, and notes that Bunny’s speed can help with Field Missions. The available guidance does not establish one universally fastest story route for every new account. See Nexon’s Game Guide and official updates.
