In battle Edit
Damp prevents self-destruction and the use of moves such as Self-Destruct and Explosion. If Self-Destruct or Explosion are selected in battle, the attack will fail and the user will not faint. Also, Damp prevents the Ability Aftermath from doing damage when its user faints. Damp affects non-adjacent Pokémon in Triple Battles.
Outside of battle Edit
Damp has no effect outside of battle.
