A Focus Band is a held item that has a 10% chance of causing an otherwise fatal attack (either direct damage or recoil damage) to leave the holder with 1 HP remaining. It does not prevent self-KO moves such as Explosion, Healing Wish, Memento, and Selfdestruct from causing the user to faint. It can be obtained as a tier 2 special drop. It is a possible drop from uncommon and rare boss Pokémon, and from wild Medicham.
Before Reforged, this item had the following recipe. It was removed due to many held items being far too easy to make.
