Splintered Stormshards is a Rock-type Z-move introduced in Pokémon Ultra Sun and Ultra Moon. It is a special move with base power tied to the user's Attack or Special Attack stat, depending on which move it is powered by. Its accuracy is guaranteed when executed. One of the unique aspects of Splintered Stormshards is that, in addition to dealing significant damage, it can remove any active terrain effects on the battlefield. This move is exclusive to the Pokémon Lycanroc when it is holding a specific Z-Crystal called Lycanium Z.
