Shrine

Rest shrines
Rest shrines are tall monoliths with a blue symbol found in quests and wilderness adventure areas that can be used to replenish hit points, spell points, and special abilities (like Turn Undead or item clickies) as well as remove negative ailments and reset the death penalty.

Rest shrines can be used only once in quests on Hard and Elite settings, once every 15 minutes on Normal and in wilderness areas, and once every 5 minutes on Solo and Casual.

Resurrection shrines
Resurrection shrines are tall monoliths with a red symbol found in quests and wilderness adventure areas that can be used when dead in order to resurrect with one hit point and whatever spell points you had at time of death. Note that you will suffer a temporary negative level due to the death penalty.

A dead player's Soul stone must be within 10 seconds of walking distance to the shrine in order to use it. Resurrection shrines can be used as often as needed.

In order to use a Resurrection Shrine with a hireling, you must be holding the Soul stone in your inventory, target the shrine, and then instruct the hireling to interact with your target. They will then be resurrected.
