When a player dies in Pantheon, he or she will have the option to wait for a resurrection or to be reborn without all of that character's gear and weapons. In either event, getting back to one's corpse is of utmost importance because it will not only restore lost gear, but some of the experience lost on death as well. Oh yes, Pantheon will have XP loss on death. Other players can help out with resurrection or retrieval spells, or players may beseech their deity for help at a cost.
In non-morbid news, Pantheon posted information and lore on the Sunken Sanctum, a marshland ruins that will be a formidable dungeon.
