• Effect: Start with 3 Teeth (カミツキ)
• Category: Defense / Counter-attack

Bite Charm equips the unit with 3 Teeth (カミツキ). The Teeth mechanic causes the equipped unit to deal 1 damage back to the attacker every time they are hit, for each point of Teeth they have. 3 Teeth means 3 damage returned per incoming hit.

Teeth is a powerful passive retaliation mechanic. 3 Teeth means every time an enemy attacks this unit, that enemy takes 3 damage back. Against enemies that attack multiple times or in rapid succession (like swarm units), this scales dramatically — each hit from the enemy becomes 3 free damage to them.

The key insight is that Teeth reward units that survive and take hits, which means it synergizes best with high-HP tanks or units with other survival mechanics (Shell, healing). A fragile unit with 3 Teeth dies before the Teeth have much time to accumulate damage. A tanky unit with 3 Teeth acts as a damage engine that punishes every attack.

3 Teeth is a strong starting value. More Teeth can be stacked through other sources, but Bite Charm alone is already meaningful in most battles.

Equip on your tankiest unit — ideally a frontline defender with high HP and possibly Shell. The more hits they absorb, the more Teeth damage they output. Your leader can work well here since they're always present.

Avoid putting Bite Charm on glass-cannon units whose main strength is attacking, not tanking. Those units should use their charm slot for offense.

Units that already have Teeth from their natural kit gain even more value — stacking to 4-5+ Teeth makes each incoming hit increasingly costly for the attacker.

• Acorn Charm / Block Charm: More Shell means more hits absorbed, more Teeth triggers
• Nourish Charm: Combined with Teeth for offense-defense loop — take hit, regain HP, deal Teeth damage
• Heart Charm (+5 HP): More HP means surviving more hits to trigger Teeth more times
• Hog Charm (+7 HP): A very tanky unit with Teeth becomes a devastating damage sponge
