Sap of the World Tree

Sap of the World Tree (known as World Tree Dewdrop in the Anime) is a revival item in ALfheim Online.

Description
Due to the fact the revival spells require one to master water and holy attribute magic, players use the Sap of the World Tree to revive fallen comrade. A drop of the glowing pink liquid is sprinkled over the player's Remain Lights and a three dimensional circle, similar to that of a revival spell, will appear. The fallen player will then be revived after a few seconds.
