Question: Is Umbracrux necessary for Andy Barrage build?

I think it is more for spread damage and faster killing but for bosses isnt better classic dagger wit GA det and DOT?

But thanks for your explanation.

Is it necessary? No. Do you wanna do a lot less damage? Sure, then don't use it.

It's for concentrated DPS for bosses

i hope mercs in season 6 can wear umbracrux
