Armor: Black Kat cloak
Helm: Black Kat cowl
Shield: Swiftstrike buckler
Weapons: Acheron, Warmaster Rocket Hammer, Argent Peacemaker, Electron Vortex along with sword and bomb ctr trinkets.
worked well enough except for the last two waves, took a long time and I didn't use the hammer that much.
Used Iron Slug too, was ok
I might try Dark Retribution and Ash of Agni with Volcanic Demo Suit/BTS and see how that goes.
I've been doing it like this:
Armor: Chaos Cloak
Helm: Chaos Cowl
Shield: Barbarous Thorn Shield
Weapons:
1: Combuster
2: Acheron
3: Dark Briar Barrage
4: Dark Retribution
Weapons i've tried and recommend:
Tortofists: The charge attack is incredibly useful in the last arena, especially in the slime and gremlin waves.
Vortex bombs: Best used in wolver, zombie and gremlin waves.
Nitronome: Does good damage and knockback, useful through the whole mission.
Stagger Storm: Good crowd control tool but it doesn't affect void zombies.
Basically you should get something to provide good DPS and crowd control. Bombs make this mission a cakewalk, especially Dark Retribution and DBB. If you only have two weapon slots then just get the bombs i just mentioned, a Chaos or a Mad Bomber set and you're fine. Status resist isn't something you should worry about here, unless you really have a problem dealing with the poison.
