Whooooooooooo! Epic fight scene is epic! Ok, so I listened to almost the entire Portal 2 soundtrack (Songs to test by) while writing this. It's actually really good for writing epic scenes. Lots of electronica-assisted soaring orchestral riffs.
This is quite a wonderfully epic scene for me and it's already got me thinking about how I can top it in the future. Tricky stuff. My inspiration for the Hork-construct monster is part Chernabog from Disney's Fantasia, part 18 colossus from Shadow of the Colossus and a healthy dose of body-horror from Neon Genesis Evangelion.
PAM is entirely grown from the D&D campaign. Thanks guys!
