When a Pokémon with Grim Neigh directly causes another Pokémon (including allies) to faint by using a damaging move, its Special Attack is increased by one stage. If its Special Attack is already at +6 stages, Grim Neigh will not activate.
If the Pokémon has 100% HP, you have 0.4% chances of capture
