Illuminate : Overworld: If the lead Pokémon has this ability, the wild encounter rate is doubled. This ability has no effect in battle.

Effect Spore : Whenever a move makes contact with this Pokémon, the move's user has a 30% chance of being paralyzed, poisoned, or put to sleep, chosen at random. Nothing is done to compensate if the move's user is immune to one of these ailments; there is simply a lower chance that the move's user will be affected.

Rain Dish : This Pokémon heals for 1/16 of its maximum HP after each turn during rain.
