Coil is a Normal-type move introduced in Generation V. It does not inflict direct damage but instead boosts the user's stats. Specifically, Coil increases the user's Attack, Defense, and Accuracy by one stage each. This makes it a highly strategic move, especially for Pokémon that benefit from both increased offensive and defensive capabilities. Because it's a status move, it has perfect accuracy. Coil is often used by Pokémon with moves that require high accuracy or that benefit from enhanced bulk in battle. Its ability to improve a Pokémon's performance in multiple aspects can potentially turn the tide in competitive play.
