The most effective way to be resurrected is through the help of a fellow compatriot. Alert your friends at once to your death and they should reclaim your inanimate corpse and carry it to the Pool of Life. There it must be bathed in the pool's waters (by typing BATHE BODY) and the pool's magical properties will return you to the living. Being bathed in the pool of life negates most of the lasting effects of your death.
Alternatively you may travel the path back to the living without aid, by performing the Rite of the Dead. Here you must call upon the Ship of Death (type SUMMON SHIP) and when the black-sailed vessel dips in to view, you must BOARD SHIP. The journey of resurrection is automatic and typically lasts a few minutes. You will then find yourself reborn at the Pool of Life wearing the alkar of rebirth. Read HELP DEATHSHIP for detailed info on the Ship of Death.
