The Warpriest of Zamorak cuirass is a hybrid body armour that scales with your defence level up to level 75 for members, or level 50 for non-members. It was once obtainable by paying 4,000 Renown from the Battle of Lumbridge to the Zamorakian quartermaster. It can now only be obtained as a drop from inside the God Wars Dungeon. At full potential, it has stats identical to a dragon platebody for members, or comparable to a mithril platebody for non-members.
If a player is wearing at least 3 pieces of warpriest armour when damaged, there's a chance that damage would be reduced.
Each piece of Warpriest armour increases the chance of the passive effect occurring by 1%, starting at 3% for 3 pieces. The maximum chance the effect can occur is 6%, if 6 total pieces of Warpriest armour are worn.
Damage is reduced to an amount equal to 10% of the initial damage minus the total number of Warpriest armour pieces worn at the time. If all 6 pieces of Warpriest armour is worn, the player will only take 4% of the initial attack.
