Accuracy determines whether a move hits, while evasion makes a target harder to hit. Moves can raise or lower these stages, and weather, abilities, items, and special move effects can also influence hit chance. Some moves never miss under normal conditions, while others ignore accuracy and evasion changes. Competitive formats often restrict or dislike heavy evasion strategies because they add randomness, so check the rules before using them. For consistent play, prefer accurate moves unless a lower-accuracy move provides an important advantage. If accuracy is reduced, switching or using a guaranteed-hit option may be safer than gambling repeatedly.
