My second ever kill on ubberoth, I made my build tanky but I think the damage is pretty good too. The fight is messy because my mechanical skill is not the best, but we got the bastard!
After many tries on season 2 and 3 (I didn’t play season 4) it is immensely satisfying to finally take him down!
Here is my build for any interested: https://www.lastepochtools.com/profile/BeardusMaximus/character/Blood_Guard_Bill
