Water Pledge

Deals damage and combines with other Pledge moves for a new effect.

Water Pledge deals damage.
Water Pledge has a special interaction with both Fire Pledge and Grass Pledge.
If another ally Pokémon uses either of those moves and the user moves before them, the user will not perform any action and instead, the ally's move will have a combined 150 power.

• If Water Pledge and Fire Pledge are used on the same turn, the second move will also create a rainbow on the user's side of the field.
  The rainbow doubles the chance for a move's additional effects to take place.
  This includes the chance to cause the target to flinch through King's Rock or Razor Fang .
  Secret Power is not affected.
  This effect can stack with Serence Grace for any effect that causes a stat stage change or inflict a major status condition except flinching .
  Due a a bug, this might cause an overflow if the combined effect reaches over 255%, and have massively reduced chances. For example Charge Beam is affected.
• If Water Pledge and Grass Pledge are used on the same turn, the second move will create a swamp on the target's side of the field, reducing the Speed of all Pokémon on that side by 75%.

If two Pokémon select two different Pledge moves but the second Pokémon is prevented from using that move by paralysis etc. nothing happens.
Water Pledge does not consume or benefit from Water Gem .
If Water Pledge combines with another Pledge move and one of the Pokémon would usually receive a same-type attack bonus , the combined attack will receive it no matter who contributed the bonus.
Water Pledge can not be used in Sky Battles.

• In Gen 5 Water Pledge has 50 power.
• In Brilliant DiamondShining Pearl this move can not be selected in battle.
