Sorry I forgot to press record before fighting last boss (new to this). And I don't really want to re-do the layer again! But I want to help fellow holy priests with TC. I find it is actually easier to solo than to run with a group. My run had Soulforges, Upper Reaches and Fractured Chambers (in that order). Last boss was Writhing Soulmass. I was able to three-shot the last boss with my anima powers combo. My item level is 202. I had 1M stored damage from floor 17 so feared boss and hit him with Holy Fire and then Shadow Word: Pain. Let the boss hit me so I can charge Scales of Trauma with Flash Heals. Feared him again and hit him with Holy Fire and he was dead on the floor with the Corridor Creeper in my bag. The important anima powers that helped me are:
Scales of Trauma x 2 - damage stored from healing done by Flash Heal/Heal (400% of max health)
Catharstick x 2 - damage stored from damage taken (not sure if it scales with HP)
Thick Burlap Sash x 10 - more HP (100% stamina)
Obleron Endurance x 10 - more HP ( 150% max health)
Cruelty Censer x 5 - damage scales when enemies are feared (175% more damage)
Wailing Visage x 5 - longer duration of fear (28secs almost nonstop fear)
Psychic Wallet x 4 - drops roughly 60 Phantasma for every mind control (I had 3k phantasma extra after the run and 9 deaths available)
I purchased Fleeting Frenzy Potion early on from broker and saved for floor 18 (30% increased damage). I wanted to have Words of Incomprehensible Glory as I had it on lower layers and it procs a lot but not lucky enough to see it.
Good luck!
