Fire Pledge is a damaging Fire-type move.
If a teammate uses Grass Pledge in the same turn, a sea of fire will be summoned on the target's side of the field for four turns that hurts non-Fire-type Pokémon for ⅛ of their maximum HP every turn. This effect is negated if it is raining.
If a teammate uses Water Pledge in the same turn, Water Pledge's effect will be triggered.
In both cases, Fire Pledge's power is doubled if it is used after the other pledge move.
