Prankster (Japanese: いたずらごころ Teasing Heart) is an Ability introduced in Generation V.
Prankster increases the priority of status moves by one. Any move that is increased in priority from Prankster is not blocked by Quick Guard.
Any status moves used by Pokémon with Prankster now can be blocked by Quick Guard.
Dark-type Pokémon are now immune to opposing Pokémon's moves that gain priority due to Prankster, including attacking moves called by Assist. Dark-type Pokémon can still bounce moves back with Magic Bounce or Magic Coat; moves that have increased priority due to Prankster which are reflected by Magic Bounce or Magic Coat can affect Dark-type Pokémon, unless the Pokémon that bounced the move with Magic Coat also has Prankster. This does not affect moves that change weather, cause entry hazards, or Trick Room.
Outside of battle
Prankster has no effect outside of battle.
