In the quest in the Bank where you have to break the Crystals to exit the Vault. What is the best way to break the Crystals? I hit them with Two Handed sword with my Fighter. Next time I run with my sorc and used Niacs. However, I ran out of spell points before I could break both and ended up hitting with Finger of Fire wand and finally my Quarter staff. It was all my Hireling Cleric could do to keep me healed and fight the defenders. He ran out of Mana too.
I completed the quest both times, but surely there is an easier way.
