Karil the Tainted is the fourth oldest of the Barrows brothers. Karil's crypt is located to the south of the Barrows area. He uses ranged equipment, although, unlike a player using his equipment, he is fairly weak to Magic attacks. Karil's set effect is Tainted Shot, which gives him a 25% chance per successful hit to lower the player's Agility by 20%. Although all damage can be avoided through Protect from Missiles, his set effect will activate regardless if the hit would have been successful.
Karil is weak to both melee attacks and magic attacks, and in particular to air spells.
