Ressurection - Imperian Online Help

4.9.1 Ressurection

If you wish to avoid both the experience loss and embarrassment of having to escape the underworld, you may seek out someone powerful in the Hunter, Shaman, Priest, Templars, Deathknights, and Diabolist professions, to resurrect you. Doing so will cost you no experience loss to come back to life.

There is one other way to return to life, and that is having your body submerged in Aryana's Spring.
