Unbound

Unbound is the single strongest trait in Anime Expeditions, adding a massive +350% damage bonus alongside a 5% attack speed increase and +10% range. No other trait comes close to its raw damage multiplier - the next highest, Draconic, only adds 20%.

The tradeoff is Unbound's Single Placement restriction: only one unit rolled with Unbound can be placed on the field at a time, no matter how many copies a player owns. That makes it a trait to reserve for a single best damage dealer rather than something spread across a team, unlike Primordial, which carries a similar profile of bonuses with no placement limit at all.

At a 0.1% base drop rate, Unbound is the hardest trait to roll naturally in the entire Trait System, but its 1,500-reroll hard pity guarantees a copy for players willing to commit that many Trait Crystals to a single unit.

Unbound is a Mythic trait with a 0.1% base drop rate, the rarest trait in the game, and a 1,500-reroll hard pity, the longest of any trait. Reaching it means committing Trait Crystals to rerolling one specific unit's trait over and over, since the Trait System tracks Unbound's pity separately from every other Mythic trait and progress does not transfer between units.

Trait Crystals for that grind come from quests, tournaments, index milestones, the battle pass, redeem codes, event rewards, calendars, shop purchases, stage drops, expeditions, and Robux material packs for players who want to speed up the stockpile.
