There's an instance zone next to Zarvonn Tower. I think you click a stone. I thought you had to get a drop from an undead to get in. I never got a drop and can't get in. Whazup?
The potion of earthwalking is access to Valley of the Magi, not Zarvonne's Tower. I think you click the grave behind it, but have to have a dropped artifact first. Anybody know if this still works?
