Key of balance

Description
The Key of Balance is a greenkey obtained during the Godslayer quest, in which a player uses it to open the World Gate so that they may find a safe place for the citizens of RuneScape to stay if Guthix destroys the world.

How to Obtain
The key is obtained by killing a Rotten Dryad, who live in Deathland, to the North-East of Rellekka. An agility level of 80 is required to access Deathland and the key is only dropped once, during the quest, and not after it or before it.
