After you complete the Vault of Ice and return to Shalek The Wise, you can either go to The Emperor's Retreat, or you can defeat 12 Hall Servants. If you want to summon the Grumish Greataxe, do the Hall Servant quest. Then you will have to defeat Bort Malletmane. Then you have to do the Vault of Ice again. Finally, you can light the braziers in the Entrance Hall and summon the Grumish Greataxe and his two minions. Good Luck!
This guy is unusually tough for Krokotopia. I would either bring some friends along, or wait till you have levelled way up! Umrag the Destroyer 02:49, March 1, 2010 (UTC)Umrag the Destroyer
