All of those dont work. For pvm, telebowa is the king. The key is to proc amp somehow and atma amulet or other ways with merc work the best.
Rotw did buff bowzon with some extra - to enemy physical resist
I have a bowa build abit different from yours, 7fpa 69fcr high hp with bo. No fancy switch, no proc no nothing just spam multishot and clear p8 lobbies.
Didnt try p8 herald but i just delete normal heralds off screen so i really dont see the problem, just takes more time in p8. You chose to fight that herald in the tight spot instead of just luring him out in the open and kill him off screen, idk.
Cool to see people try out new things anyway
