One of the strongest weapons in the game currently. The primary fire feels like a lex prime but hits a truck. Getting 12 headshots charges up it's Incarnon mode (can be shortened to about 3-4 shots with multishot). Switching to Incarnon mode with alt-fire makes it feel like a pocket [Acceltra] with small AOE on impact but with significant damage. This build is a raw damage crit oriented build using Overwhelming Attrition.

Evolution Choices

• Evolution I - Incarnon mode

• Evolution II - Rapid Wrath: +20% Fire rate. Can use recoil perk if you don’t use one of Secondary Deadhead or Steady hands.

• Evolution III - Lethal Rearmament: +90% reload speed on headshot at 3 stacks, but only affects untransformed. Currently the Feather of Justice perk is bugged in that it applies to other weapons
  too, but I expect this will get patched

• Evolution IV - Caput Mortuum: +50% headshot damage

• Evolution V - Overhwleming Attrition: non-crit and non-status hits trigger a +400% bonus for 20s, up to 1200% which is additive to Hornet Strike/Deadhead.

When not taking into account [Xata]'s whisper, Overwhelming Attrition has a higher average damage multiplier and is more consistent when compared to Devouring Attrition when taking into account headshots. This is because having an additive 1200% bonus active for ALL shots including critical hit and headshots averages out to be higher.

Calulations of Devouring Attrition vs Overwhelming Attrition

Devouring Attrition

With no crit mods + hornet strike (2.2) + deadhead (3.6) + elemental excess (-10% crit):

• 88% chance to do no crit with 50% chance to get 2000% multiplicative with hornet strike/deadhead
  - 44% chance to do 21x(1+3.6+2.2)=142.8x
  - 44% chance to do 1+3.6+2.2 = 6.8x
• 12% chance to crit and do (1+3.6+2.2) x 2.2=14.96x

Average Damage multipliers
Bodyshots: 44%x142.8 + 44%x6.8 + 12%x14.96=67.6192x on bodyshot

Headshots: 75% x (44%x142.8 + 44%x6.8 + 12%x2x14.9) + 25% x (44%x142.8 + 44%x6.8 + 12%x2x14.9) x 3 x 1.3 = 135x on headshots
(Now that the AOE component doesnt get headshot multiplier, only 25% of the damage receives the 3x headshot multi. Deadhead still appies 1.3x to both AOE and non AOE parts, and is also multiplicative to the base 3x multiplier.)

Void damage instance with [Xata]'s Whisper + Devouring Attirtion
On bodyshot: 44%*142.8x21+44%x6.8+12%x14.96=1,324 x base damage x [Xata]'s Whisper % ([Xata]'s whisper double dips Devouring attrition)
On headshots and taking into account faction mods, this becomes 21,502 x base damage x [Xata]'s Whisper% ([Xata]'s Whisper also double dips 2x headshot multiplier, 1.3x bonus of deadhead and 1.55x of primed bane)

Overwhelming Attrition

Assuming 100% uptime at max stacks giving additive 1200% on all hits with galvanized crosshairs (max stacks), primed target cracker and secondary deadhead (max stacks):

• 92% crit chance to do (1+3.6+12) x 4.62=76.692x
• 8% chance to not crit 1+3.6+12= 16.6x

Average Damage Multipliers

• No headshots and running Primed Pistol Gambit (63% crit): 63%x76.692+37%x16.6=54.458 =53.126x base damage on bodyshots (lower than devouring attrition by 20%)
• No headshots and running exactly 85% crit chance: 85%x76.692+15%x16.6=67.6782x on bodyshots (Just exceeds devouring attrition).
• No headshots but running max stack Galvanized Crosshairs (92% crit): 92%x76.692+8%x16.6=72x base damage on bodyshots (exceeds devouring attrition by 35%)
• All headshots: after some maths this works out to be approximately 250-300x multiplier if all your shots are headshots (this is because the headshot multiplier is 3x but only applies to the non-AOE component, and is multiplicative to caput mortuum/deadhead (1.8x), and applies an additional 2x multiplier from critical headshots).

TL,DR:

Use Devouring Attrition if you can't aim at heads (67.6x multiplier vs 54x multiplier) or want to run [Xata]'s Whisper (approx 600x vs 54x on bodyshots and approx 10,000x vs 400x on headshots)

Use Overwhelming Attrition if you can aim at heads for up to 3x higher damage (398x multiplier vs 135x multiplier on headshots and 72x multiplier vs 67.6x multiplier on bodyshots) and don't want to run [Xata]'s Whisper. Running Cascadia [Overcharged] and dropping Crosshairs for Hornet Strike also gives higher average multiplier on both headshots and bodyshots)

Mod Breakdown

• [Galvanized Diffusion]: +230% multishot at max stacks, meaning you get at least 3 bullets per shot with a 30% chance for 4. This allows you to basically do 3x more damage AND charge incarnon mode 3x faster.

• [Galvanized Crosshairs]: At max stacks gives +320% critical chance making a final crit chance of 92%. Even at such as high crit chance, you still have approximately 5% chance per shot to activate a stack of Overwhelming, meaning approximately one shot in every 20 shots activates the buff (consider you can shoot about 12 shots per second with multishot and fire rate, meaning you will have a 20s buff refreshed every 2s). [Primed Pistol Gambit] is an alternative to Crosshairs. NOTE You only get the +320% crit chance when AIMING down sights. This means you can actually exceed 100% crit chance with stacking Primed Pistol Gambit or Cascadia Overcharge, but still activate overwhelming attrition by shooting while not aiming down sights.

• Primed Target Cracker: Adds +110% crit multiplier to hit 4.6x

• Primed Expel: A further 1.55 multiplier to hornet strike/deadhead and Devouring Attrition and double dips on heat procs giving them 2.4x multiplier. Use regular expel mod if no primed version as it is still a 1.3 or 1.69x multiplier. Flexible for primed fulmination or hornet strike if you dont like faction mods.

• [Lethal Torrent]: Brings multishot to 3.9 so 90% of shots give 4 bullets, and gives fire rate (combined Rapid Wrath gives +80% fire rate total)

• Viral 60/60: Gives status chance and viral procs. One viral status gives a 2x multiplier on all subsequent hits, adding up to 4.25x multiplier at max 10 stacks.

• [Primed Heated Charge]: Biggest elemental mod bonus on pistols to multiply raw damage. Heat procs also strip armor by 50% and can stack indefinitely, which each new stack refreshing all existing stacks.

• Steady Hands: Combines with Deadhead to give -100% recoil for laser point accuracy. [Lethal Momentum] is an alternative but this requires changing polarity.

We do not need to run [Hornet Strike] or galv shot because Overwhelming Attrition is additive, but if you have empty slots these can be added.

Flexible options
For corpus: Swap [Frostbite] and Primed heated charge for Pathogen Rounds to make pure toxin and add anemic agility.
For infested: Swap Frostbite for Jolt/Convulsion to make Corrosive Heat

Arcanes
Scondary Deadhead is mainly run for the -recoil and +headshot bonus.
Cascadia Overcharge is an alternative option on frames with consistent overshields (eg Pillage/Condemn), that frees up the Crit mod slot (galv crosshairs/primed pistol gambit), which you can then put something like Primed Fulmination or Hornet Strike.

Orange Crit Laetum - Cascadia Overcharge

Combining [Galvanized Crosshairs] and Cascadia Overcharge can give you a total of +620% crit chance for a final crit chance of 158% on aiming down sights with overshields, or approx 60% orange crits. But how do we activate Overwhelming attrition if every shot is a crit? Simply shoot from the hip (don't aim down sights) so [Galvanized Crosshairs] does NOT activate. This means you will be only getting about 90% crit chance from Cascadia Overcharge. Alternatively aim down sights while not having overshields to also activate overwhelming buff.

At 158% crit chance but without deadhead, the final average multiplier becomes 457x (vs 399x from 92% crit chance)

Here is an example of Orange Crit [Laetum] without [Harrow] (using hip fire to proc Overwhelming, then aiming down sights to get orange crits):

.

Red Crit Laetum - Harrow + Xata's Whisper

The void damage instance of Xata's Whisper currently counts as as non-crit non-status component of [Laetum]'s damage and therefore will proc Overwhelming Attrition regardless of your crit chance. This means you can run [Harrow] with [Xata]'s Whisper and achieve RED CRITS while still getting the +1200% dmg of Overwhelming Attrition.

At 308% crit chance (achievable with [Harrow] Covenant + Arcane Avenger + [Primed Pistol Gambit] + Deadhead) on headshots, your final average multiplier actually becomes approx 1200x and you get guaranteed red crits.

With [Galvanized Crosshairs] fully stacked, Cascadia [Overcharged], Covenant and Avenger active, you can hit 403% final crit chance, meaning guaranteed tier 4 red crits (although you need to drop Secondary Deadhead and run the -recoil perk to maintain -100% recoil which actually reduces overall average DPS with final multiplier of approx 1100x). This is an example of a case where forcing yourself into the next tier of crits actually reduces your DPS.
