PS: About the gems, someone today mentioned that spirit gems are no longer what people normally use now so maybe I've been missing out a little with wrong gemming. However as I said that I use robot and icy veins for my reforging and gemming I hope it's not wrong..
ALSO, I'm glad that Druids are OP and that my concerns haven't been that bad. I manage to get close to him but not quite.
That's a crapton of spirit.....
Spirit is a comfort stat. Only gem as much as you think you need (with a flask on).
I'm not telling you to drop 2-3k spirit, but... you could probably start ditching it until you find yourself going OOM near the end of the fight.
