Didn't expect a new boss on a "minor patch", much less for it to be the hardest by a long shot! Very enjoyable fight, though phase 1 is kinda eh.
Gonna experiment with this boss to get it done with no heals, hopefully without debuffing her attack speed too!
My strat here is to use crits with Scythe of Blossoms to quickly dispatch phases 1 and 2 (getting a crit on the strong attack of the scythe deals massive damage). Then for phase 3 switch to a Fresh Toenail Scimitar to reduce it's attack speed + Lv3 Swordmaster to further reduce it's damage output.
Regarding it's attack patterns, I think the most important think to note is that if she's away when the fog is dense it seems like she either goes for a screech or either of the jump attacks.
There's still a bunch of stuff to learn, like how to dodge the bomb projectile up close. Also don't think it's worth it to destroy the explosive eggsacs.
