Litmus

Litmus is an Ability exclusive to the Minus World. It is exclusive to Minus World Eevee.

When a Pokémon with this Ability uses a Normal move, its type randomly changes to a type no target is immune to, which can occasionally be Normal, ???, or Weird. However, the move retains STAB (if Eevee is still a Normal-type) and all boosts associated with Normal moves (such as those from Plates or type-boosting items).

This Ability was introduced in Pokémon XY Naturia, being one of two concepts introduced there (the other is the Pixie Hat).
