The sacred clay body is a piece of Ranged body armour, bought in Stealing Creation minigame, which has stats identical to the Blue dragonhide body. This armour requires 50 defence and 50 range to wear.
It gives 24,450 bonus experience in the Ranged skill. It can be recharged by visiting the rewards mystic and paying 20 Stealing Creation points. When uncharged, it can still be used as ranged body armour, with identical stats.
