Assurance is a Dark-type move with 60 power and 100% accuracy. Its power doubles to 120 if the target has already taken damage on the same turn. Assurance is particularly useful in multi-battle formats or when paired with moves that inflict damage first, making it effective for dealing significant damage to already weakened foes. This move can strategically capitalize on a teammate's initial strike or residual damage from status effects like poison or burn. Its unique mechanic makes Assurance a versatile option in various battle scenarios.
