Roost (move)

Roost is a -type status move that recovers health. It is TM19 and can be found on Route 7.

Effect
Roost restores half of the user's maximum HP.

If a Flying-type Pokémon successfully uses Roost, until the end of the turn, its Flying type is ignored when it is hit by attacks: If the Pokémon has another type, only that type is considered; if the Pokémon is a pure Flying type, all attacks will be normally effective against it.
