OK, I'm a level 30 storm/life wizard, and I just spent an hour by myself defeating the vault of ice, and I forgot to rub the obelisk. What do I do? Is that required for anything? Should I go to a different world and level up before I come, or finish Krokotopia and come back, or redo it?
No it's not required because if your talking about the tall pointy obelisk in the last battle then it's not required and you could come back for the xp later or get some help.
