After casting <Shockwave Surprise> or <Shockwave Surprise · Resonance>, grants self 5 layers of [Shockwave Amplification] (each layer increases Mastery by 3% and the DMG coefficient of <Heartshatter Finale · Resonance> by 10%, up to 30 layers). When other allies cast skills outside their turn, self casts <Shockwave Surprise · Resonance> once (triggers up to 2 times before each of self's actions). When other allies cast skills to a Boss, self casts <Shockwave Surprise · Resonance> once (triggers up to 1 time before each of self's actions).

Carnival Overload Lv.2At the beginning of a battle, grants Boomagi [Eternal Revelry] (all allies' non-Critical DMG taken is reduced to 1, and they are immune to Control effects; loses 1 layer at the end of self's turn).

Carnival Overload Lv.3When consuming [Resonance Point] to enter [Resonance Enhancement], acts immediately for 1 turn, refreshes the CD of <Shockwave Surprise> and <Heartshatter Finale>, and increases the Turn Meter of all other allies by 20%.

When clearing [Shockwave Amplification], additionally grants self 1 layer of [Everlasting Heartcore] and 1 layer of [Eternal Revelry] (triggers up to 2 times per battle). When casting <Heartshatter Finale · Resonance>, forces all non-Boss enemies to act immediately for 1 turn; during this turn, enemies can only launch Basic Attacks, and Spirit Beasts' charge rate is reduced by 50%. DMG dealt by <Heartshatter Finale · Resonance> ignores [Shield] and [Damage Immunity] effects. When 5 allies with the [Internal Injury] tag are deployed, DMG dealt by <Shockwave Surprise · Resonance> and <Heartshatter Finale · Resonance> to Bosses is increased by 200%.
