Stat Rerolls are one of the best ways to increase a unit’s overall power in Anime Expeditions. Even if you own the strongest Secret or Mythic unit, poor stat rolls can significantly reduce its performance. By rerolling stats, you can improve your unit’s Damage, Range, and SPA (Seconds Per Attack), allowing it to deal more damage and clear stages much more efficiently.
This guide explains how Stat Rerolls work, every stat tier, their drop rates, and how to transfer stats between units.
Anime Expeditions Stat Reroll Guide
Every unit you summon comes with three random stat bonuses:
- Damage
- SPA (Attack Speed)
- Range
These stats are assigned a rank, ranging from F (worst) to Z (best).
Using a Stat Reroll changes all three stats, giving you another chance at obtaining stronger rolls.
Higher-ranked stats provide larger bonuses, making Stat Rerolls an important part of maximizing your strongest units.
Stat Rankings
Stat quality is divided into the following tiers:
- Z
- SSS
- SS
- S
- A+
- A
- A-
- B+
- B
- B-
- C+
- C
- C-
- F
Z Tier is the rarest and strongest, while F Tier provides the weakest bonuses.
How to Reroll Stats
To reroll your unit’s stats:
- Go to the Stat Potential area in the lobby.
- Interact with the Stat Potential NPC or station.
- Select Stat Reroll.
- Choose the unit you want to improve.
- Click Reroll.
- Your Damage, SPA, and Range stats will be rerolled.
Every reroll consumes one Stat Reroll item.
Using Stat Locks
If you already have one or two excellent stats, you don’t have to reroll everything.
You can use Stat Locks to protect specific stats during rerolls.
For example:
- Lock Damage
- Reroll only SPA and Range
Each locked stat consumes one Stat Lock every time you reroll.
If you lock two stats, you’ll spend two Stat Locks per reroll.
Because Stat Locks are limited, it’s usually best to save them for high-tier rolls like SS, SSS, or Z.
Stat Tier Bonuses
| Tier | Damage | SPA | Range | Roll Chance |
|---|---|---|---|---|
| Z | +17.5% to +20% | -12.5% to -15% | +12.5% to +15% | 0.15% |
| SSS | +14.9% to +17.4% | -9.9% to -12.4% | +9.9% to +12.4% | 0.80% |
| SS | +11.1% to +14.8% | -6.1% to -9.8% | +6.1% to +9.8% | 1.75% |
| S | +9.1% to +11% | -4.1% to -6% | +4.1% to +6% | 2.20% |
| A+ | +8.1% to +9% | -3.1% to -4% | +3.1% to +4% | 3.25% |
| A | +7.1% to +8% | -2.1% to -3% | +2.1% to +3% | 4.00% |
| A- | +6.1% to +7% | -1.1% to -2% | +1.1% to +2% | 5.25% |
| B+ | +5.1% to +6% | -0.1% to -1% | +0.1% to +1% | 8.75% |
| B | +4.1% to +5% | 0% to +0.9% | -0.9% to 0% | 10.00% |
| B- | +3.1% to +4% | +1% to +1.9% | -1.9% to -1% | 13.00% |
| C+ | +2.1% to +3% | +2% to +2.9% | -2.9% to -2% | 15.50% |
| C | +0.1% to +2% | +3% to +4.9% | -4.9% to -3% | 23.50% |
| C- | -2.6% to 0% | +5% to +7.6% | -7.6% to -5% | 7.55% |
| F | -5% to -2.5% | +7.5% to +10% | -10% to -7.5% | 4.30% |
Note: Lower SPA values are better because they reduce the time between attacks, allowing units to attack more frequently.
Best Stat Rolls
If you’re aiming to maximize a unit, these are the most desirable stat tiers:
Damage
- Z
- SSS
- SS
SPA
- Z
- SSS
- SS
Range
- Z
- SSS
- SS
Ideally, your strongest units should eventually have SS or higher in all three categories.
How to Get Stat Rerolls
Stat Rerolls can be obtained from several sources, including:
- Redeem Codes
- Beginner Path rewards
- Story Mode
- Quests
- Challenges
- AFK Rewards
- Daily Login Rewards
- Daily Calendar
- Events
Story progression and limited-time events are among the most reliable ways to earn large numbers of rerolls.
How to Get Stat Locks
Stat Locks are rarer than Stat Rerolls and should be used carefully.
You can obtain them from:
- Codes
- Quests
- Challenges
- Story rewards
- Daily rewards
- AFK rewards
- Event rewards
Because they are limited, avoid using them on average stat rolls.
How to Transfer Stats
Anime Expeditions also allows players to transfer stat rolls from one unit to another.
This is especially useful if you’ve rolled amazing stats on a weaker unit but later summon a stronger character.
How to Transfer Stats
- Visit the Stat Potential station.
- Select Stat Transfer.
- Choose the unit that will sacrifice its stats.
- Choose the unit that will receive those stats.
- Select which stats you want to transfer.
- Spend the required Gold to complete the transfer.
What Happens During Stat Transfer?
After transferring stats:
- The sacrificed unit loses its transferred stats.
- Its Stat Potential resets.
- Its Level resets.
- The receiving unit inherits the selected stat rolls.
This feature allows you to preserve rare Z or SSS rolls instead of trying to obtain them again through rerolling.
Stat Rerolls are one of the most impactful upgrade systems in Anime Expeditions, allowing you to optimize a unit’s Damage, SPA, and Range far beyond its base stats. While achieving perfect Z-tier rolls is extremely rare, steadily improving your strongest units through rerolls, Stat Locks, and Stat Transfers is a much more efficient long-term strategy. Focus your resources on high-rarity characters, protect valuable rolls with Stat Locks, and take advantage of the Stat Transfer system to avoid wasting exceptional stat combinations.
