Compoundeyes

Increases the Accuracy of all moves used by this Pokémon by 30%. This is a multiplicative increase, not additive, meaning if a move has 50% Accuracy before Compoundeyes, it is brought to 65% total Accuracy afterward. When a Pokémon with this ability is first in the party, wild Pokémon will have a higher chance of holding an item.
