Pit of Eternal Sands Amulet Holder location
After removing the seal that leads to the Pit of Eternal Sands and defeating the Azdaha boss, you’ll gain the Gravity Wings time power (i.e. double jump). Make your way to the upper-right section of the zone, well past several rooms with giant centipedes and pillar traps.
Eventually, you’ll come across a lone Wak-Wak Tree. Beyond this point, there’s an encounter against several statue heads and harpies. Defeat the hostiles and open the chest to receive another amulet slot upgrade in Prince of Persia: The Lost Crown.
