Im thinking to make plague and phoenix for my dragondin backup .
What weapon i should use eth ba ? Barb swords . Pls help me mates .

He cant use BA
A5 merc can only use swords, and most popular one would often be x2 phase blade grief as he can also dual wield

Superior 15/3 ethereal colossus sword w/ death rw inside it, might be able to use 2 of these on him idk, or dual 15/3 phase blade grief/edeath

eth up headstriker

unsure if the d2r changes to allow them to dual wield eliminated the bonus you'd get from a 1h weapon on d2c.

eth up'd headstriker used to be king because of that, no idk.

What was the exact bonus u would get in terms of increased dmg?
