Damp prevents all Pokémon from using Self-Destruct, Explosion, Mind Blown, and Misty Explosion; if a Pokémon attempts to use one of these moves, it will fail and the user will not faint or take damage. Additionally, Damp prevents the Ability Aftermath from doing damage when the Pokémon with Aftermath faints.
The floor becomes defused, preventing all explosions, including moves such as Explosion and traps such as the Explosion Trap. The
Blast Seed and Blast Wand will also become ineffective in the presence of a Pokémon with Damp.
Blasts from things like the move Explosion, Blast Trap, or Big Blast Trap will not go off.* No moves like Explosion or traps like Blast Trap and Big Blast Trap will work while the Pokémon is on the floor!*
If the opponent tries to use Selfdestruct of Explosion near Defense Forme Deoxys, the opponent with start to glow brightly, and so will Defense Forme Deoxys's core. The opponent then stops glowing and it cannot explode.
