Storm Drain

All other Pokémon's single-target Water-type moves are redirected to this Pokémon, if it is an eligible target. Other Pokémon's Water moves raise this Pokémon's Special Attack one stage, negating any other effect on it, and cannot miss it. If the move's intended target also has this ability, the move is not redirected. When multiple Pokémon with this ability are possible targets for redirection, the move is redirected to the one with the highest Speed stat, or, in the case of a tie, to a random tied Pokémon. Follow Me takes precedence over this ability.

The Pokémon draws in all Water-type moves. Instead of taking damage from them, its Sp. Atk stat is boosted.
