For absolutely wailing on someone with this weapon, you can change out the respective Smite mod in favor of Combo Duration/Combo Chance if you're feeling like your team is killing to many things to make the smite count.

FYI:

• If you don't have an Umbra Forma, just use two regular forma.
• Make sure to use Arcane Fury for TONS OF DAMAGE.
• If you want more attack speed, you can use Arcane Strike OR (not recommended) replace Gladiator Might with Gladiator Vice & replace Organ Shatter with Quickening
• If you're feeling spicy, you can replace Gladiator Might with two elemental mods.
