Defeat the mutated Dimitrescu.
Story related, can’t be missed
At the end of the castle, after placing all four masks on the statues and moving across a bridge into a church, you will have a cutscene and the boss fight will begin! The only attacks to avoid are her mount’s dash, signaled by its head turning red,and the swarms she sends after you. I suggest hitting her, preferably with headshots, with the Shotgun while she is grounded, and with the sniper when she is airborne. A clip or two is all you need for the sniper on casual, and maybe a stack of Shotgun shells. And don’t forget a med or two, just in case!
