I bought one from the battle Maison and I don't know what to do with it. Help?
It changes the ability of a Pokemon which has 2 abilities to its other ability. eg: You can give an Ability Capsule to a Frisk Noivern and change its ability to Infiltrator. But you can not get Telepathy however much you try. And neither can you get frisk/infiltrator from telepathy.
Because, sadly this DOES NOT WORK with hidden abilities.
Hope I helped :) Source: Experience
Ability Capsules changes your Pokemons normal abilities around, DOESN'T WORK for hidden abilities mind, at all!
Example:-
Kangaskhan has 3x abilities Scrappy (Normal) Early Bird (Normal) Inner Focus (Hidden Ability)
Kangaskhan has 3x abilities
Scrappy (Normal) Early Bird (Normal) Inner Focus (Hidden Ability)
Kangaskhan is found here<<<<<
Only normal abilities can be changed back and forth but not hidden ability. That stays the same (sadly).
Hope I Helped.
