Gen IXThe Pokémon will always act more slowly when using status moves, but these moves will be unimpeded by the Ability of the target.
Mycelium Might in Battle
Mycelium Might is a Generation IX ability with a distinctive trade-off: the Pokemon always moves last when using status moves, but those moves completely bypass the target's ability. This means status moves like Spore, Will-O-Wisp, or Thunder Wave will ignore abilities that would normally block them, such as Overcoat, Magic Bounce, or Insomnia.
The speed penalty applies only to status moves -- damaging moves operate at normal priority and speed. The ability essentially functions as an automatic Mold Breaker exclusively for non-damaging moves, at the cost of always being outsped when using them. This creates a strategic dynamic where the user can guarantee landing a crippling status condition but must survive the opponent's attack first.
Mycelium Might is found on 2 Pokemon, both Grass-types: Toedscool and Toedscruel. For Toedscruel in particular, combining Mycelium Might with Spore creates one of the most reliable sleep inducers in the game -- Spore's 100% accuracy plus ability-ignoring effect means only Pokemon with type immunity (Grass-types) or held items (Safety Goggles) can avoid being put to sleep. The guaranteed slow speed on status moves is a meaningful drawback in fast-paced competitive matches, however.
