Patch V0.21

Last verified 2026-07-29

V0.21 overhauled tournaments for Silver tier and above by applying two battle conditions that scale harder in higher tiers and intensify over later waves. It also introduced PLUS upgrades, a new unique ability for each Ultimate Weapon unlocked once you own them all, and kept Ultimate Weapon timers synchronized throughout a round. The rest of the update was quality-of-life and stability work: locked cards during boss fights, a cap on UW toggling, cloud save improvements, six upcoming event relics, and a batch of bug fixes.
