Revive sickness(10s): You recently revived yourself and are still recovering.
Double-click to be revived from death. This will destroy the orb. This item cannot be used in PvP or WvW.
— In-game description
- Using this item causes a ghost to appear and revive you. You will be under the effect of Revive sickness; it lowers your HP to 1, and applies cripple for 10 seconds. Once revived, you will not be invulnerable, such as it is with other revival methods, but will rather go into Revive sickness for a short period of time.
- Do not use this item if your corpse is being continuously damage (like sitting on top of a steam vent). Either the orb's healing power may not be able to overcome the damage you are taking, or you may instantly die after being revived.
