1-4 Bleed Stacks on non-Weak Spot Hits.
5-8 Bleed Stacks on Critical Hit.
Immune to Ranged Attacks for 0.7-1s on Close Range Kill.
Suppress Enemies within 5-8 Radius on Close Range Kill.
This build focuses on getting crits to proc Faith Restored which is easier to proc with Bloodletting.
Combat Knife
Secondary weapon is up to you. Flamer is highly recommended as well as Bolter (see reference doc at bottom)
Kept fairly basic as I am still trialing out what I want to focus on. I personally don't like stacking Toughness curios as I do not understand how this helps my character or any character for that matter. As this build already has 90% toughness dmg reduction I don't think adding more is beneficial. In my experience toughness can break near instantly and chip damage is unavoidable therefore having more health keeps you up longer. Toughness can be regained from kills or using your Ult.
Corruption resist - I don't like that Fatshark decided to split Grimoire out of general Corruption resist considering its the same infliction to our health pool. In any case the non-grim corruption is still good as this would help against everything else i.e. Bosses, Hounds, etc. considering parties more than likely are not picking up grims in Damnation.
Stamina/Block Eff - allows you to spam more push attacks with knife and block eff to help manage bosses, elites, re-positioning, etc. Don't really need combat regen since this is managed by Invocation of Death.
Faith Restored - getting crits give us tough damage reduction which is guaranteed from our Ult and 15% base crits on Knife, and are more likely to occur using Push Attack.
Bloodletting - with Knife + Lacerate blessing getting bleeds to further increase crits is easy choice.
Benediction - converts your 7% passive to 15% and complements with Faith Restored gaining us up to 90% toughness dmg reduction.
Thy Wrath Be Swift - this talent is quite valuable and stops us from getting interrupted during reloads, shooting, melees, and also allows you to hack stations without getting knocked off.
Rising Conviction - best choice as its always active and doesn't rely on you micromanaging your health.
Invocation of Death - complements this build as its easy to get crits.
