That whole build up led to a very disappointing final battle. I'm not asking for a whole new mechanic for fighting him, but just make him difficult. The golems were far more of a threat. It's attacks do about twice as much as the boss', and he has nearly twice the armor (Just making up these figures from my fighting because I didn't manage to get all of the eyes).
I just started this game, I am only level 19. I enjoy it, but the one complaint i have is that gold just doesn't do anything. It only goes so far, i think there should be a way to but planet coind with gold.
