Pokémon Black Version and Pokémon White Version - Water Pledge, Fire Pledge, and Grass Pledge
If two of these three moves are combined in a single turn and the attack is successful, an extra effect is created as follows:
- Water Pledge + Fire Pledge - A rainbow appears on the user’s side. For four turns, including this turn, the chance of additional effects from attacks by any Pokémon in battle on the user’s side that isn’t rotated out is doubled. (This effect is cumulative with Serene Grace . Secret Power not affected.)
- Water Pledge + Grass Pledge - A swamp appears on the target’s side. For four turns, including this turn, the Speed of each Pokémon in battle that isn’t rotated out on the target’s side is multiplied by 1/4 .
- Fire Pledge + Grass Pledge - A sea of fire appears on the target’s side. For four turns, including this turn, each Pokémon in battle that isn’t rotated out on the target’s side, other than Fire types, loses 1/8 of its maximum HP (but not less than 1 HP) at the end of each turn except the last (this HP loss is not reduced if a Pokémon has Heatproof).
The extra effect is not reset if the same combination of moves is used before the effect ends. The extra effect is not considered an additional effect for the purposes of Sheer Force or Shield Dust.
