Book 6 / Final Boss Tips
I did it with Lilith/white lady/bloody mary.
I went to get a ton of health through the relic that gives +20/+20 hp/sp but sets your max escence to 30 and then hitting up a lot of events.
Builds do a ton of damage without doing many attacks tend to be the plan with some way of healing. Hell’s brasero does a ton specially (specially combined with a white lady ) (and you’re going to be limited in amount of attacks anyways).
White lady feels like a must in the fight as she both has great healing or a strong sp damage that ignores all the bosses passives.
It is worth noting the sp damage still gets reduced, i finished her off with my bloody mary doing the , attack once/depleted skill for about 500 damage , and just tanked all the sp damage i got with 100 max sp + wall.
You generally want scaling attack of some kind so a relic like warhorn is worth a lot.
Besides that have a lot of skills so you can still attack in every situation.
