A unique Attack that deals 10 (14 upgraded) AoE and repeats on every kill. Exceptional in hallway fights with many low-HP enemies, chaining into wholesale clearance at 1 energy. Apply Weak or Frail first to soften the field and improve the chain rate. Less useful against high-HP boss fights where the chain never triggers. Specialized for hallway sweeping. Upgraded 14 AoE reaches more 1-shot thresholds for bigger chains.

• Shines in multi-enemy hallway fights. Targets with 10–14 HP chain-repeat the effect into full wipes.
• Soften enemies with Poison first, then Reverberate drops them into the 10–14 range and triggers the chain.
• Stack Weak or Frail to tune damage to exactly lethal for the whole board.
• In boss fights, the chain never triggers — treat it as plain 10–14 AoE damage. Consider pick-by-floor context.
• Upgrade to 14 brings more enemies into 1-shot range, making chains more frequent.

• Noxious Fumes / Deadly Poison: shave HP with Poison so Reverberate chains cleanly.
• Corpse Explosion: AoE damage on Poison triggers. Chipping the board with Corpse Explosion first sets up Reverberate's chain.
• Dagger Spray: AoE Attack. Use before Reverberate to lower HP, then chain.
• Terror: Attacks deal double damage vs. Weak enemies. Weak first, then Reverberate for 20–28 AoE and easy chains.
