Traits are passive bonuses you attach to units in Anime Expeditions, and they change how a unit performs without touching its base kit. Some raise raw damage, others cut attack timing, extend range, boost critical hits, or increase the income a unit generates. Rolling the right one is the fastest way to make a strong unit hit harder or fire faster.
Quick answer: Head to the Trait Reroll stand in the in-game hub (it sits between the Crafting and Evolving stands), pick a unit, and spend one Trait Crystal per roll. Each roll swaps the current trait for a random one based on its drop chance, and the four rarest traits are guaranteed once you hit their pity count.
Every Anime Expeditions trait, effect, and drop chance
Each trait carries a fixed effect and a set roll chance. The three basic stat traits appear most often, while the high-end traits stack several bonuses and show up far less. SPA refers to a unit’s attack timing, so any trait that lowers SPA makes the unit attack more often. RNG is the unit’s attack range.
| Trait | Effect | Roll chance |
|---|---|---|
 Strength 1 | +5% DMG | 14.64% |
 Speed 1 | -5% SPA | 14.63% |
 Range 1 | +5% RNG | 14.63% |
 Enlightenment | +50% EXP gain | 9% |
 Strength 2 | +10% DMG | 7% |
 Speed 2 | -10% SPA | 7% |
 Range 2 | +10% RNG | 7% |
 Limit Breaker | +15% DMG | 6% |
 Precision 1 | +10% Crit Chance, +5% Crit DMG | 6% |
 Precision 2 | +20% Crit Chance, +10% Crit DMG | 4% |
 Bolt | -15% SPA | 4% |
 Optics | +25% RNG | 3% |
 Investor | +25% income | 2% |
 Draconic | +20% DMG, +50% DoT, -10% unit cost | 0.5% (300 pity) |
 Forsaken | +35% Crit DMG, +35% Crit Chance, +10% RNG | 0.3% (500 pity) |
 Primordial | +35% DMG, -15% SPA, +20% RNG | 0.2% (750 pity) |
 Unbound | +350% DMG, -5% SPA, +10% RNG | 0.1% (1,500 pity) |
Unbound is the single strongest trait in the pool thanks to its +350% damage line, but at a 0.1% chance it is also the hardest to land on a natural roll.
How to reroll a unit’s trait
You know a reroll worked when the unit’s listed trait changes in the menu to the newly rolled one. If you want to grind toward a specific rare, hold the Reroll button to auto-reroll, but open Filters first and select which traits you want so the process stops when your target appears. Every roll, manual or automatic, still counts toward the pity total for the rare traits.
Where to get Trait Crystals
Trait Crystals are the only currency that lets you reroll, so a steady supply matters if you plan to chase a rare trait. Clearing maps is the most reliable source, and you can top up for free through daily rewards, in-game mail gifts, and event drops during updates.
Redeemable codes are another quick source. The RELEASE code grants 30 Trait Crystals and 2,500 Gems, EA+ gives 30 Trait Crystals and 2,500 Gems for EA+ holders, and EA gives 20 Trait Crystals and 2,500 Gems. Redeem them by pressing the three-dots button in the top-left corner, choosing Redeem Codes, and entering a code. Codes are time-limited, so claim them early inside the official Anime Expeditions Roblox experience.
How the pity system guarantees rare traits
The four rarest traits each track a pity counter that rises with every reroll and forces the trait once you reach the threshold. This protects you from an endless unlucky streak on the lowest-chance rolls. The rarer the trait, the higher its pity count climbs.
| Trait | Pity (rerolls) |
|---|---|
| Draconic | 300 |
| Forsaken | 500 |
| Primordial | 750 |
| Unbound | 1,500 |
Because pity accumulates per unit, it pays to funnel all your rerolls into one carry rather than spreading Trait Crystals across the roster. Hitting 1,500 rolls on a single damage dealer eventually forces Unbound, even if you never hit its 0.1% chance naturally.
Which traits to prioritize
There is a clear gap between the top and bottom of the pool. High-end traits stack multiple stat boosts at once, while common traits improve a single stat. Unless you are a brand-new player still building a roster, it is worth saving rerolls for the higher tiers.
| Tier | Traits |
|---|---|
| S+ | Unbound |
| S | Primordial, Forsaken, Draconic |
| A | Investor, Bolt, Precision 2, Optics |
| B | Limit Breaker, Speed 2, Range 2, Strength 2, Precision 1 |
| C | Enlightenment, Speed 1, Range 1, Strength 1 |
Unbound sits alone at the top and outclasses everything else because of its 350% damage line. Primordial, Forsaken, and Draconic all combine several powerful buffs and stay useful across nearly every mode, which makes them the traits worth spending pity to secure for endgame and leaderboard runs.
The A and B options are strong fallbacks while you are still assembling a team or run low on crystals. Investor is the standout pick for farm units, since the extra income helps the rest of your roster scale faster. Bolt, Precision 2, and Optics deliver solid single-stat gains that carry the early game, and the B tier reliably beats the basic stat traits. The C tier traits are only worth keeping until something better lands, since every trait provides some benefit until you roll an upgrade.
The practical approach is simple. Pick one main damage dealer, pour your Trait Crystals into that unit alone to build pity, and set your auto-reroll filter to catch anything in the S or A range. Damage dealers gain the most from Strength tiers, Limit Breaker, or the stacked rares, attack-speed units benefit most from Speed, Bolt, and Primordial, and Investor is the call whenever you want a unit to fund the rest of your board.
