Armadyl armour is high level range armour that is commonly used by higher level players. The Armadyl armour set is made up of an Armadyl helmet, chestplate, and chainskirt. You can get the set from another player or as a drop from Kree'arra and her minions in the God Wars Dungeon. This set is some of best range gear in the game and has similar stats to Karil's armour. It is very commonly used because of its high magic defence bonus (+122). Both Armadyl and Karil's armour are surpassed by Pernix armour.
To equip this armour you need level 70 Defence and level 70 Ranged.
