Bolt

Bolt is a pure Legendary speed trait that cuts a unit's SPA (seconds per attack) by 15% and touches nothing else - no damage, range or crit bonus is attached. Traits in Anime Expeditions layer on top of a unit's Stat Potential grade and its tier stats, so Bolt's -15% SPA modifier stacks with whatever SPA grade the unit already rolled, compounding into a genuinely faster attack cycle rather than replacing it.

The practical effect of a smaller SPA number is more attacks landed per second, which matters most on units whose passives trigger off Regular Attacks - charge counters, stack-based follow-ups and cooldown-gated procs all fire more often when the base attack cycle shortens. On a unit with no such hook, Bolt is still a clean DPS increase, just a less compounding one.

Within the wider Trait System, Bolt sits in the Legendary tier alongside traits like Limit Breaker, Optics and the two Precision traits, one step below the four Mythic traits that combine multiple stat bonuses into a single roll.

Bolt is a Legendary trait with a 4% base drop rate and no documented hard pity, rolled the same way as every other trait - a fresh summon has a 75% chance to land some trait, or an already-owned unit can be rerolled by spending a Trait Crystal, the consumable material dedicated to trait rerolling.

Trait Crystals come from quests, tournaments, index milestones, the battle pass, redeem codes, event rewards, calendars, shop purchases, stage drops and expeditions, so stockpiling them from regular play before committing to a reroll session is the standard approach described in the Trait System.
