Hitting at least 3 enemies with an attack, increases your damage by 24-36% for 3 seconds.
2.5-4% Bonus Critical Chance on Chained Hit. Stacks 5 times.
30-60% Rending on Critical Hit.
4.5-6% Critical Chance for each expended round in your weapon (resets on reload).
This is the truest embodiment of support, just as the Emporer would want. Still well capable of 500k damage in Aurics.
Revolver for Carapace and Specials, you can eliminate several caparace enemies for your team per reload, and manage snipers and key targets. 25% carapace puts you into 3-5 shot kills on Crushers and 2 shots on maulers, plus cleave. I like crucian over surgical becuase I find myself quickly emptying my gun when I need it for carapace, and dont really need crits to deal with specials as long as you hit headshots. So I would rather have my crit go up in the second half of the clip especially after handcannon rending is applied.
Evicerator II - An oldie but goodie, like many of the relics we play with. It has a fantastic Push Attack > Heavy rotation as well as a nice H1 > L2 > H1 rotation. Once you get comfortable you can also H1 > L2 > L3 cancel, but I dont find myself needing it. I personally take Rampage and Shred > But if you are not feeling tanky enough you can swith Shred to Momentum for the additional toughness gen. Additional cleave is not neccesary so I personally avoid those blessings.
This build has significant damage reduction and hp replenishment so you can always let your teammates heal first.
Purity is another very under rated selection as clearing corruption becomes more valuable in higher difficulties in correlation with less Medicae charges.
Stunstorm grenades plus chorus give so much cc. Be sure to ping downed allies before you start preaching so teammates know to come revive.
Now go be the support you wish to see in the world!
Alternative Weapons:
Crusher - Flak, Maniac, Skullcrusher, Hammerblow - The CC'est
Evic XV - same perks and blessings, a more dps focused weapon with less cc because light attacks instead of heavy
Boltgun - Carapace, Unyeilding, Shattering Impact, Pining Fire - less mobile, worse for specials, lots of fun
Bolt Pistol - Flak, Carapace, Puncture, Lethal Proximity
