Anime Expeditions Traits: Reroll Effects Guide
Anime expeditions traits guide explaining permanent bonuses, reroll rules, Trait Crystals, key traits, pity notes, and smart keep decisions.

Quick answer
Anime expeditions traits are permanent bonuses applied to individual units. The collected sources say traits can improve damage, reduce SPA, increase range, improve crit, lower placement cost, add damage over time, or increase income. Rerolling a trait replaces the current trait, so players should decide whether a unit is worth long-term investment before spending Trait Crystals.
The most important trait names from the research are Unbound, Primordial, Forsaken, Draconic, and Investor. Unbound is described as the best overall trait, Primordial as a flexible damage trait, Forsaken as a crit trait, Draconic as a DoT trait, and Investor as a farm or economy trait. Exact numeric values need verification unless checked in game.
What traits do
Traits are one of the main ways to make Anime Expeditions units stronger after you obtain them. Beebom says traits can provide higher damage, increased range, and damage over time. Animeexpeditions.top adds that traits may affect SPA, crit, placement cost, or income.
Because traits are unit-specific, the same trait is not equally valuable everywhere. A carry wants damage or scaling. A farm unit may want economy value. A critical-hit unit benefits more from crit-focused traits than a unit that does not use that strength well.
How to get traits
The sources agree that players use Trait Crystals to reroll traits. MrGuider describes the Trait Reroll Machine in the lobby Upgrades area, while another source describes the Trait Reroll stand in the same general lobby upgrade area. Each reroll replaces the unit's current trait.
One source states the reroll cost as 1 Trait Crystal per roll. Because costs can change after updates, treat that value as needing verification before making a final cost table. Codes can provide free Trait Crystals, which is why the codes page connects directly to trait progression.
Key trait list
Unbound is the top priority in the collected trait materials. It is described as a best overall or S+ trait and a powerful choice for a main carry. Best-traits research notes a one-placement restriction, so it should not be recommended blindly for every unit.
Primordial, Forsaken, and Draconic are repeatedly placed in high tiers. Primordial is framed as a flexible premium damage roll, Forsaken as a crit-focused trait, and Draconic as a DoT-focused trait. Investor is not a carry trait; it is useful because it fits farming or economy units.
Reroll rules
The most important reroll rule is simple: rerolling replaces the current trait. If a unit already has a usable trait, rolling again can make the unit worse until another good result appears. This is why trait rerolls should be saved for units you expect to keep.
Do not spend rare Trait Crystals on temporary units unless you need immediate progress. The collected notes repeatedly suggest focusing rerolls around role and investment value. A good trait on the wrong unit can still be a poor resource decision.
Codes are relevant here because several researched code rewards include Trait Crystals. That does not mean every code will always fund trait rerolls, because codes expire and rewards change. It does mean new players should check the codes page before spending earned crystals from normal progression.
Traits by role
Main carries should usually chase the strongest damage or scaling traits that fit their kit. Unbound and Primordial are the main examples from the research, though Unbound's restriction means it should be evaluated carefully. Critical DPS units can look toward Forsaken if their kit benefits from crit.
Damage-over-time units fit Draconic better than units with no DoT emphasis. Farming or economy units fit Investor because income value is the reason to use them. If the source does not confirm a unit-trait pairing, mark it as needing verification rather than presenting it as a fixed build.
FAQ
Are common traits useless? Not always. Beebom says common traits often improve a single stat, which can still help early or midgame accounts. They are weaker endgame targets, but they may be acceptable while the roster is still forming.
Should every unit chase Unbound? No. Best-traits research warns that trait decisions should follow unit role. Unbound is a high-ceiling trait, but not every unit is the correct place to spend enough resources chasing it.
Trait information that needs verification
The collected trait sources agree on broad rankings and role ideas, but exact values should be handled carefully. Damage, range, SPA, crit, and income values may change with updates. If the page later adds a numeric trait table, every value should come from current in-game confirmation or a recent source.
Pity thresholds also need caution. Some sources discuss pity or reroll rules, but the collected notes are not enough to publish final pity numbers here. Until those values are verified, this guide should explain the system without pretending to know exact odds.
How traits connect to equipment
Traits and equipment should be planned together. A main carry with a strong trait and compatible gear can become much more valuable than the same unit without setup. A farm unit with Investor and useful economy support can affect stage tempo differently from a DPS unit.
When choosing a trait, check the unit's role and gear direction. If the gear improves Magical damage, it belongs on a compatible Magical unit. If the trait supports DoT, it should go to a unit that actually benefits from DoT. Anything else needs verification.
Beginner trait approach
Beginners should focus on understanding replacement risk before chasing perfect traits. If rerolling replaces the current trait, then a decent early trait may be worth keeping while the roster is still unstable. Save heavy reroll sessions for units that appear in your long-term carry, support, farming, or control plan.
If the unit's future role is unclear, mark the choice as needing verification and wait until your team plan is clearer. Spend crystals only when the trait can support a confirmed job.
