WARNING POSSIBLE SPOILER READ AT YOUR OWN RISK...
i got 3 out of 4 items in order to form the strongest hammer (i think) that can be forged in the game. i have the scroll, the hammer thunderwhatever +3 and the ogre gauntlets, and i thought i had all of it when i said i have the belt of the hill giants, but noooo... i need the belt of FROSTGIANT... i am in chapter six now and before i face bohdi i wanna get the hammer... does anybody know where the last item or the belt of the FROST GIANT is??? thanks =)

I think you mean the Girdle of Frost Giant Strength. If you are in Chapter 6 and am preparing to face Bodhi, then I think you may have missed it as it was in the Underdark. BUT all is not lost, just go back in via the way you came out. It is in the KuoTua dungeon accessed to the extreme left of the Underdark map.

SPOILER coming............

Go to the room which has the statue of Demogorgon. If you click on the statue it will say something about a sacrifice. *hint* Your spellcasters summoning capabilities will be useful here. Be prepared for a fight, as the...thing that has it will not give it up easily.

The girdle of frost giant strength is on one of the Demon Knights in the Koa Toan part of the Underdark.

thanks guy... i remember that place since i had no idea what to sacrifice to that statue so i thought it was worthless... any ideas? pls. thanks

like i said, summon something and make it walk onto the altar.
