I can't find the key to the frost giant place, searched the whole fortress, the lower level, and killed the lizardmen in the caves below but still no key. I'm stumped.
I didn't find a key to continue after the hill giants. What I found to lead me further on was a scroll that mentions giants. I'm pretty sure I found it on a giant of some kind, possibly on the hill giant king but I'm not sure.
What's with people who answer their own questions? I guess they're just stupid.
I found a scroll in the basement but it said something about building plans and that it was no use to the party.
Yes, but there's another scroll, written in Giant, which the party can't read. I can't remember which enemy carried it, but once you have it you go to Cassam in Torbury and he deciphers it and asks you if you want to teleport to the Frost Giant dungeon.
