3.5-5% Strength for 3.5s on Hit. Stacks 5 times.
Continuously chaining more than 2 attacks gives 2-5% Power. Stacks 10 times.
Ranged hits add 1-4 stacks of bleed to enemies.
Point blank shots cause an explosion. Explosion Radius increases by 10-25%.
You can also swap to the Combat Axe MK III for an easier time against Hordes at the loss of some DPS.
Mostly reccomend Bolt Pistol as you can shoot it point blank to create space to make up for your lower Horde Clear however most weapons will work in this build but i would reccomend sticking to something focused on Ranged Special killing.
Other notable options if desperate are Damage Resistance (Snipers) so they dont chunk your health if they hit you, Damage Resistance (Bombers) to allow you to pass through gas clouds with less corruption & Revive Speed (Ally) to speed up saving your team.
If looking for more Survivability you can take 1 point from Duelist to pick up Enemies Within, Enemies Without.
Immolation Grenade can be used in a pinch to help with Horde Clear or reviving.
