the quest island of lost souls doesnt depend on the chest its a different story ^-^ when u take the quest, this will enable u to turn wisps at the island into gaurds which can protect u against enemies if they come there, the guards will disappear in a period of time idk it :PTo make a 1wisp into 1guard u need to have the quest + 1[Eye Of Ravva], this will help u stay longer at the island to wait till the chest respawns so u can open it.. but opening the chest has nothing to do with having the quest :friends:
