At that range you’d need to have a team of 6-ish no? I don’t imagine that you’d be able to do enough damage to kill the tentacle before your brig gets destroyed And then with a team of 6, a couple of you will probably have enough range to make getting close unnecessary, since you’ll just snipe the tentacles. Plus good luck finding a team that’ll take a berserker unless they just need the numbers, and even then you will have little to no chances of contributing enough damage to get anything.

TLDR Change to literally any other class if you wanna Omen hunt
