Correction for pledge moves Water Pledge, Grass Pledge and Water Pledge.
The slow from the Grass Pledge with Water Pledge, the "swamp envelops the foe's team" QUARTERS opponents' speed for 4 turns, not halves.
The damage from the Grass Pledge with Fire Pledge, the "sea of fire envelops the foe's team" damages NON-FIRE TYPE opponents 1⁄8 of their maximum HP each turn, for 4 turns, rather than all opponents.
Also less important to add but the Water Pledge with Fire Pledge, the "rainbow appears in the sky on your team's side" doubles the chance of moves' secondary effects occurring for 4 turns, BUT SPECIFICALLY DOES NOT STACK WITH SERENE GRACE FOR FLINCH CHANCE. This one might be too niche to be worth the edit is still a feature.
