Increases the accuracy of all moves used by the wielder by 30%. This is a multiplicative increase, not additive, meaning if a move has 50% accuracy before Compoundeyes, it is brought to 65% (0.5 * 1.3) total accuracy afterward. When a Pokemon with this ability is first in the party, wild Pokemon will have a higher chance of holding an item.
This ability is useful on Pokemon with low-accuracy moves, and fortunately, many of the Pokemon with this ability have low-accuracy moves to exploit. Galvantula and Butterfree are possibly the most well-known of these; Galvantula can make great use of a 91% accurate Thunder, while Butterfree can use a 97.5% accurate Sleep Powder and Stun Spore.
