Party Detonator

Party Detonator (rare) is the upgraded form earned by completing the Party Detonator sidequest. Like the sidequest version, it causes each dying unit to explode in confetti dealing 5 damage and knocking back nearby units 2 tiles, and fires a once-per-battle active that deals 999 damage to a random unit (capped at 25 vs. bosses). The exact mechanical difference between this and the sidequest form is not fully documented.
