Zealot
2.5-4% Bonus Critical Chance on Chained Hit. Stacks 5 times.
Critical Hits ignore Hit Mass bonus from Armour. {crit_damage} Melee Critical Hit Damage.
Use whatever melee weapon you want, but perks should be Crit Chance and Crit Damage. If using a chain weapon, Shred is a must for one Blessing; I like Perfect Strike as a second, but Bloodletter could probably work too given the Scourge talent synergy.
I like a long range option for my gun, but this build can work with any ranged weapon you like.
At least two Curios should be +1 Wound - Bleed for the Emperor is more effective the more wounds you have, you're pretty much getting +40% damage reduction on any hit you take with 7 or 8 wounds.
