Description

In case your character is not protected by all available regular blessings at the time of death, you have the option to purchase the blessing Death Redemption in the Store. Death Redemption will restore all skill and experience points you would not have lost if you had been protected by all available regular blessings. Death Redemption can only be purchased within the next 24 hours after death. While it is possible to purchase Death Redemption for several deaths, only the last death for which Death Redemption has not been used yet will be displayed. Earlier deaths will be displayed once you have restored later deaths.

The Death Redemption is not available in Retro Hardcore PvP Game Worlds.
