I just finished my first play through of the game yesterday and this fight sold me on the future of this game.
Inspiration for this fight clearly came from Akylios, a raid boss from a little known MMO called Rift. It is one of my favorite boss fights of all time and I always kind of thought it would be cool if someone could figure out how to replicate it in an ARPG. World First Akylios by Voodoo - YouTube
