Absolutely demolished this run. Advancing Whirlwind is a little awkward on its own because you can't dodge while it's going, but if you get Psychic Whirlwind to take care of that, it becomes truly frightening. Throw in the Hephaestus bonus damage on top along with enough mana regen that I could wind up spin attacks indefinitely and I was basically unstoppable.
I think the only thing that could have made this better is if I had managed to get lucky and get a third hammer from Echo to make the spin attack charge faster.
