I'm glad i did it, woot woot ~>_<~
What I learned is that it heavily depends on the core you have equipped...night and day... had amp crit + amp atk and HP and it was shit barely made 11 mil...went for amp agl + 2x amp atk to have it done in 2:30 mins with 2x speed full auto...
Yeah, I agree.. the core is the most important part for one shot bosses. My Bathory has an amp crt with 2x amp atk, isn’t the best for fever damage compared to your but it works fine on crts. :)
I gave bathory a amp atk core with amp agl and amp crit, but i killed the boss around 4 mins, maybe that's because i don't use theresa in my team (she is now under development)
