Frozen Giant - Four Skulls
I got the frozen ore and completed Fershid's quest, which opened up the dialogue with Four Skulls in the Cavern of Icicles. When I talk to Four Skulls ("Sir Giant"), it says "He stands stiff and cold as stone." I know I'm supposed to use the burning hand spell to thaw him. I use a burning hand scroll, and it just says he is a friendly creature and I shouldn't attack him. I can't thaw him. I've tried burning hand, great burning hand, and fireball. I am only using scrolls, since I am playing as a pure ranger and trying to avoid learning any attack magic spells. What should I do?
