Karil's equipment is obtainable from the Barrows minigame. The full set consists of the Karil's Coif, Top, Skirt, and Crossbow . This armour requires 70 Defence, and 70 Ranged to wear. Karil's is mostly used for its exceptional Range bonus. Karil's armour is one of the rewards from the Barrows minigame.
Often when a player does not receive any barrows brother items, they can however receive Karil's bolts, which can only be used in his crossbow.
