• Effect: Replace Attack with apply Overload (バクハツスンゼン)
• Category: Offense / Conversion (Overload applicator)

Flameblade Charm completely transforms the equipped unit's attack into an Overload application. Instead of dealing direct damage, the unit now applies Overload (バクハツスンゼン) stacks to the enemy. Overload is a debuff that causes the enemy to explode dealing damage proportional to accumulated stacks.

Flameblade converts a damage-dealer into an Overload engine. The unit's Attack stat is replaced by Overload application, meaning the old Attack value no longer matters — what matters is how many Overload stacks the unit can accumulate on enemies.

The key insight is that Overload deals massive burst when it detonates. A fast unit with Flameblade that applies Overload every 2-3 turns rapidly charges the enemy's explosion threshold. Combined with other Overload sources, this creates synchronized detonations that wipe out enemies with no direct damage needed.

The obvious weakness: the unit no longer deals direct damage. If the enemy is eliminated by other means before Overload detonates, the Flameblade unit contributed nothing. In decks without Overload synergy, Flameblade converts a damage dealer into a mediocre debuffer with no guaranteed payoff.

The unit's Attack stat from Battle Charm and similar bonuses become irrelevant after Flameblade conversion.

Build an Overload-focused deck. Flameblade works best on a fast-Counter unit that applies Overload repeatedly. Combine with Boonfire Charm, other Overload applicators, and allies that stack Overload to build to devastating detonations.

Avoid on units in non-Overload builds.

• Boonfire Charm: Consume trigger applies Overload to all enemies, stacking onto Flameblade's work
• Bom Charm: Bom and Overload are different debuffs — applying both creates compound explosive pressure
• Fast Counter unit: More Overload stacks per battle cycle
• Multiple Overload sources: Synchronized detonation from all Overload stacks going off at once
