Originally, the set consisted of only a helmet, chestplate, and chainskirt. However, with the God Wars update on 5 September 2012, it received gloves, boots, a buckler for the shield slot, and a main-handed crossbow. Unlike the original items, the new crossbow initially required 70 Ranged to wear. This was changed on 26 May 2015 to a level 75 Ranged requirement in line with other God Wars weapons.
Armadyl armour is strong, does not degrade, and has a Ranged bonus; as such, it is often preferred to Karil's equipment, which has higher defensive bonuses. Armadyl armour is most often used for training combat and Slayer, and for fighting bosses at higher-levels.
