Fight went a lot better when I realized I could actually facetank the slam and use its long-ass animation as a DPS window. Still died to the bullet hell because I'm pretty terrible at those as you might've noticed. :p

Current build: https://pobb.in/PD5H_qlHfCVG just switch the Quicksilver flask for the Sapphire one (which has increased chance to freeze/shock/ignite, I figured it couldn't hurt and I have the defensive buffs on the other ones). Current worth is about 150-170 divines, nearly half of which is from the weapon. (70d and then about 12-16d worth of Power Runes for the runecraft)
