Hey everyone! I'm currently in Dedraka's Descent (cleared zoned), working on the Visions of Vetrovia:Evil Dedraka quest. I'm on the last part where I need to, "examine the residual corruptive energy found near Zagg the Unburied". I know the corruptive stone is behind the 3 epics, but for some reason it's unclickable. I already defeated everything in this zone, not sure why I can't click on the rock to get the quest update. Does anyone know? I've already done this zone twice.
