Zealot
7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
3.5-5% Strength for 3.5s on Hit. Stacks 5 times.
4.25-5% Strength for every Enemy you Stagger. Stacks 5 times.
Target receives 1-4 Stacks of 2.5% Brittleness on direct projectile hit. Debuff lasts for 5 seconds and can have a maximum of 16 stacks.
Choose whatever ranged weapon you prefer, I'm enjoying the double barrel at the moment. Flamer would also be great and benefit well from the 25% damage boost from Anoint in Blood
Zarona revolver with Hand cannon and Surgical would also be great for anti-carapace and popping snipers etc
