Cleric Beast +0 (Hitless)
Of course, the winning attempt is the one where I tragically whiff the opening transforming attack on his head...
This was much harder than expected, he has one-damage hitboxes on his feet during the multi hit combos which infuriated me to no end. I also tried not to use fire paper for quite a while (I didn't want my plans to involve having to farm), and I kind of think buffless +0 will be too much for this run, the damage difference is absurd. Ultimately, when I stopped being stubborn and finally dropped the lock on, things got much easier.
