The Perene Bones is a quest, available as soon as Harvest Amethyst is finished.
5 Perene Bones need to be collected in Temple of Ibalize (Outer) for this quest to be completed. They are collected automatically when undeads located in the dungeon are defeated (Undead Warrior, Undead Crusader, Undead Gladiator).
As the enemies in the dungeon consist of undeads only, the quest is completed very early and the following quest can be done in the same dungeon run.
