In One Piece Bounty Rush, upgrading a character is a sequence of separate systems: EXP orbs raise the level, fragments increase the grade and level ceiling, skill orbs and Bounty Coins improve skills, medals add traits, and Boost or Hyper Boost provide later development. The most efficient approach is to build a small team around its roles instead of spending every resource across the roster. Open each character’s current upgrade screen before spending anything, because requirements and resource sources can change with updates.
This guide explains what each layer does, the order that normally makes sense, how to choose characters for a team, and what to do when an upgrade appears locked. Bandai Namco describes training characters as “the key to victory” on its official How to Play page.

Think of progression as a stack rather than one level bar. Each layer uses different resources and solves a different limitation:
| System | What you spend | What changes | Where to verify it |
|---|---|---|---|
| EXP level | EXP orbs | Raises the character’s current level until the grade limit | The character’s level screen |
| Grade-up | Character fragments and the resources shown in the client | Raises the grade and extends the level ceiling | The character’s grade-up screen |
| Skill level | Skill orbs and Bounty Coins | Improves each skill independently | The individual skill screen |
| Medals | Bounty Coins and medal materials shown by the game | Adds traits and can open more randomized trait slots | The medal crafting and upgrade screens |
| Boost and Hyper Boost | The current Boost-screen requirements | Adds later character-development layers | The character’s Boost screen |
Level and grade are not interchangeable. A character can reach the current grade’s level limit while still needing fragments for the next grade. Conversely, a grade-up does not replace the EXP needed to fill the newly available levels. Skills and medals are separate again, so a high level alone does not mean the character is fully developed.

The official game page lists more than 350 characters, a roster snapshot observed on November 12, 2026; that number can change as updates add or remove availability. With a roster that large, concentrating resources on a role that your team actually needs is usually more effective than trying to advance everyone at once.
How do I level up a character with EXP orbs?
EXP orbs raise a character’s level inside the current grade. They do not, by themselves, raise the level cap.
- Open the character-management screen and select the fighter you want to develop.
- Choose the level or training option and review the EXP-orb cost shown for the next level or batch of levels.
- Spend the displayed amount, stopping when the character reaches the current grade’s limit.
- If the level bar will not advance further, switch to the grade-up screen instead of continuing to spend orbs elsewhere.
The exact amount of EXP needed can vary by the character’s current level and the live game version. Use the number displayed in your client rather than a static guide or a screenshot from an older update. If you are short on orbs, reserve them for the characters you have selected for your active team and support setup.
Why did my level stop before the apparent maximum?
The visible maximum is controlled by grade. Reaching the current grade’s cap is expected; the next step is to meet the fragment requirement and grade up. After the grade-up succeeds, return to the level screen and spend EXP orbs on the newly available levels.
How do character fragments raise the level cap?
Fragments are the gate between grades. They are used on the grade-up screen to improve the character and extend the level ceiling; they are not a substitute for EXP orbs.
- Select the same character and open its grade-up panel.
- Read the fragment requirement and any other materials listed there.
- Confirm that the fragments are for the character you intend to advance and that you are not draining materials reserved for another team member.
- Confirm the grade-up, then return to the level panel and use EXP orbs on the levels unlocked by the new grade.
There is no reliable universal English cost table for every grade and character. The secondary leveling guide from MMODude also cautions that Bandai Namco does not publish one fixed table for all cases. Treat the live character screen as the authority, especially after a balance or content update.

When deciding where fragments go, ask whether the character fills a missing team job, whether its skills fit your current play style, and whether you can support it with medals and team effects. A slightly lower-grade unit that completes a balanced lineup can be more useful than a higher-grade unit that duplicates a role you already have.
How do I upgrade skills?
Skills have their own progression track. Raising the character’s level or grade does not automatically raise skill levels.
- Open the character’s skill panel and select the first skill.
- Check the skill-orb and Bounty-Coin requirement shown for the next level.
- Upgrade only when the displayed cost fits your resource plan, then repeat for the other skill.
- Read the skill description after each increase so you know what changed and whether the improvement supports your chosen role.
The documented progression uses skill orbs and Bounty Coins, but costs are not universal. Do not copy a fixed number from an old guide; check the individual skill screen in the current client. If a skill is unavailable, the panel should identify the missing resource or prerequisite.
Prioritize skills that directly support the job you expect the character to perform. For an attacker, that may mean the skill you rely on to pressure opponents; for a runner, it may be the skill that helps create a safe treasure route; for a defender, it may be the skill that protects a secured area. This is a team-building recommendation, not an official ranking of any particular character.
What do medals do, and how do I improve them?
Medals are an equipment layer that adds traits to a character. They are not another character level, and changing a medal loadout can alter how the same fighter performs without changing its grade.
- Open the medal menu and choose a medal or slot on the character’s loadout.
- Review the traits already present and compare them with the character’s role and the rest of your team.
- Use the crafting or upgrade option only after checking the Bounty-Coin cost and the possible result.
- When the game offers an additional trait slot, read the randomized result and decide whether it improves the build before committing further resources.
The leveling guidance describes medal crafting and upgrades as spending Bounty Coins and opening additional randomized trait slots. Because the result is randomized, avoid spending every coin on a medal that gives little value to your current lineup. Keep a functional set equipped while you develop better options, and reassess the traits whenever you change the character’s job.

Medals are also a reason not to judge a character by level alone. Two characters with similar levels can have very different effective builds if one has traits that reinforce its skills, role, or team effects and the other does not.
What do Boost and Hyper Boost do?
Boost 1, Boost 2, and Hyper Boost are later progression layers that sit beyond ordinary leveling, grade-ups, skills, and medals. They are best treated as long-term investments after your core team is functional.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Open the character’s Boost panel and read the requirements for the next node or stage.
- Check which materials and currency the current version requests; do not rely on a universal list.
- Compare the benefit with the cost and with the needs of your active team and support characters.
- Confirm the upgrade only after verifying that the materials are not needed for a more urgent grade-up or skill level.
The available guidance does not provide a universal English requirement table for Boost or Hyper Boost. Requirements can differ by character and change with updates, so the live Boost screen is the only dependable cost reference. If a guide gives a fixed list without a version and character context, use it as background rather than as a shopping list.
What order should I use for scarce upgrade resources?
A sensible order is to establish a role-focused team, fill each character’s current level, grade up when the cap is reached, improve the most relevant skills, build medals, and then move into Boost and Hyper Boost. This order keeps early resources from being stranded on a character you do not use.
- Choose a core team. Select characters you already use or realistically expect to use together. Consider role coverage, elemental or Character Type Effects, and the support roster rather than one impressive statistic.
- Raise current levels. Spend EXP orbs until each selected character reaches its present grade limit.
- Grade up the priority units. Use the fragment requirement shown on each character screen, then fill the newly opened levels with EXP orbs.
- Improve key skills. Spend skill orbs and Bounty Coins on the skills that matter most for each character’s job.
- Equip and refine medals. Give the active roster useful traits first; use additional randomized slots when the cost is justified.
- Develop support and team effects. The official guide recommends upgrading support characters, setting medals, and using Character Type Effects to strengthen the party around the active fighters.
- Invest in Boost and Hyper Boost. Move here when the core team is stable and the current screen shows that you can afford the requirements.
This is a resource-management recommendation, not a publisher-mandated order. If a current event or mode makes one resource unusually plentiful, you can adapt the sequence while keeping the same principle: improve the team that you actually field before spreading materials across the entire roster.
How should I choose characters to upgrade?
Choose by team job and complementarity, not by level alone. Bandai Namco’s official class descriptions give a useful starting point:

| Class | Officially described job | Questions to ask before investing |
|---|---|---|
| Attacker | Specializes in defeating enemies | Can the team create openings for this character, and do its skills support sustained pressure? |
| Runner | Specializes in getting treasure | Does the lineup need a dedicated scorer, and can the runner reach or escape from treasure safely? |
| Defender | Specializes in defending treasure | Can this character hold the areas your team captures while the other roles rotate? |
The class labels describe jobs, not a universal ranking. The official site does not designate one best character or one mandatory upgrade order. Compare the character’s role with your current roster, available fragments, skill resources, medals, and support development. A balanced party that can attack, capture, and defend may make better use of resources than three units built for the same job.
Also consider whether a character’s Type Effects complement your support characters. The official How to Play material presents support development and Character Type Effects as broad team-development levers, so evaluate them alongside the active fighter rather than as an afterthought.
Where can I find the resources for upgrades?
Resource sources and event rewards can change, so the current game client is more useful than a permanent farm list. Check the reward panels for the modes you play, event notices, exchanges, missions, and any resource-specific section available in your version. The important distinction is which resource you need: EXP orbs for levels, fragments for grade-ups, skill orbs and Bounty Coins for skills, and the materials named on the Medal or Boost screen for those systems.
Before claiming or exchanging a reward, open the target character’s upgrade panel and note the remaining requirement. This prevents a common mistake: collecting a large amount of a general currency while still lacking the character-specific fragment or skill material that actually blocks progress.
Because the game is updated, record the date when you consult a farming recommendation. A source that was accurate for an earlier event may not describe the rewards or menu paths in the November 2026 client.
What common mistakes slow character progression?
- Confusing level with grade. EXP stops at the current grade limit; fragments are what extend that limit.
- Using a universal cost chart. Requirements are shown per character and can change. Verify every purchase in the live screen.
- Ignoring skills. A high level does not automatically improve skill levels. Open each skill and check its separate materials.
- Spending coins on random medal results without a plan. Randomized trait slots can consume Bounty Coins, so keep a useful baseline set equipped.
- Building one favorite while neglecting the team. Attackers, runners, defenders, support characters, medals, and Type Effects all contribute to a lineup’s performance.
- Starting Boost too early. Boost and Hyper Boost are later layers; confirm that your core levels, grades, skills, and medals are in place first.
- Assuming a paid purchase is required. The game is free to play, although the official page notes optional paid items and loot boxes. The progression steps above use in-game systems and do not require a physical copy or accessory.
What should I do when an upgrade is locked or the button is missing?

- Level cap reached: open Grade Up and check the fragment requirement.
- Insufficient fragments or currency: note the precise resource and use the current reward or exchange panels to locate it.
- Skill unavailable: select the individual skill and review its skill-orb and Bounty-Coin requirement.
- Boost unavailable: open the Boost panel and read any prerequisite or character-specific material listed there.
If the requirement seems inconsistent with an older guide, trust the current client and check the game’s latest notices. The reviewed sources do not establish different character-upgrade costs for Steam, iOS, or Android, even though the game is available through the App Store, Google Play, and Steam. Do not assume a platform difference unless the current clients explicitly show one.
Is spending money required to unlock a character’s full potential?
No. Bandai Namco presents ONE PIECE Bounty Rush as free to play, while also noting that it contains optional paid items and loot boxes on the official game page. The documented upgrade path—EXP, fragments, skills, medals, support development, and Boost systems—is performed through the game’s progression resources.

A practical full-potential checklist
Use this checklist whenever you start developing a character:
- Identify whether the character is serving as an attacker, runner, defender, or support unit in your planned lineup.
- Open the current character screen and record the next level, grade, skill, medal, or Boost requirement rather than relying on a fixed online number.
- Spend EXP orbs up to the current grade limit.
- Use the displayed fragments to grade up, then fill the new level range with EXP orbs.
- Upgrade the skills that matter most for the character’s job with the listed skill orbs and Bounty Coins.
- Equip medals with useful traits and upgrade them only after checking the coin cost and randomized-slot result.
- Improve support characters and Character Type Effects so the active fighter benefits from a complete team setup.
- Move to Boost 1, Boost 2, and Hyper Boost after the core build is stable, verifying every current requirement in the Boost panel.
- Recheck the character after updates, because costs, rewards, menu labels, and available events can change.
Following these steps turns “upgrade my character” into a sequence of decisions: level the unit, raise its grade, develop its skills, equip purposeful medals, strengthen the surrounding team, and only then spend on the later Boost layers. That approach keeps scarce materials focused on characters that actually help your lineup win matches.
Frequently Asked Questions
Do all characters need the same number of fragments for a grade-up?
Not necessarily. The available leveling guidance does not provide one universal English cost table, so open the specific character’s grade-up panel and use the requirement shown there. Recheck it after updates instead of copying a number from another character or an older guide.
Why does a character still feel weak after reaching a high level?
Level is only one layer of development. Skill levels, medal traits, support characters, and Character Type Effects can change how well the unit performs in its intended role, so inspect those systems before spending more EXP.
Can I use the same medals on an attacker, runner, and defender?
You can change medal loadouts, but the best traits depend on the job each character performs and on the rest of the team. Compare the medal’s traits with the character’s skills and your objective instead of treating one set as universally optimal.
Are upgrade costs different on Steam and mobile?
The reviewed official sources confirm availability on Steam, the App Store, and Google Play but do not establish platform-specific differences in character-upgrade costs. Check the current client you play and do not assume a difference without an explicit in-game requirement.
