Blood Shot is Post add, AFTER AMP and on shot bonuses, making further investment inefficient for damage.

Bloodshot still converts our shot into skill damage, allowing us to benefit from Skill crit chance and damage.

The primary action skill choice is Incarnate thanks to Witchy Trigger Finger or Grave Harvest access. And Geistwave for bosses. However use of Phase Phamiliar is fine as an aggro relief choice. (also cute cat!). The primary goal of the Action Skill is to be active for Essence Leech and Enchantment.

Phase Phamiliar now also gains Unsealed, so you can run the Cat in every scenario!

GUNS:

We want to front load our damage into 1 shot with AMP. So high damage weapons or weapons with lingering projectiles are the optimal choice.

Truck - Primary choice weapon. Fun sniping, high power. I run multiple at once.

- Torgue impact for Viles. Extra fun with Airburst enhancement.

- Daedalus Shotgun for more bleed consistency.

- Ripper mag for Active Fire funny.

Solar Temper - Charge up but exceptionally high damage with Active Fire.

Order AR with the 'Kill Drone' underbarrel is peak mobbing for us. Activate AMP, fire it off, and watch the sparks fly.

Rooker Great for mobbing support or Boss one shots. Lacks consistency.

Jakobs Shotgun with underbarrel 'Spread Launcher'. We all know it. 1 shot potential through the roof, can one shot any health bar in the game, even with limited supporting gear.

Order Sniper The Piktun. The king of non-underbarrel boss 1 shot kills. Capable of 1 shotting most things you point it add. Limited bleed consistency for boss fights.

Stickies with Daedalus shotgun ammo swap using Contamination for better bleed consistency.

Capable of 1-Shotting Hardcore Son of Terra

Any strong, kinetic gun of choice will also work, there is no Sniper rifle limitation. Ideal for guns that have a lower hit count that struggle to benefit from the Kill Skill build.

Cormano is a personal favourite.

Class mod:

Vex Class Mod Psion. Bossing choice: With as many Bloodletter points as you can.

Teen Witch Best mobbing option. Overall good damage with Grave Thirst.

Undead Eye Backup choice. Skills don't really matter on this one. Blood Shot points are good for weapons with low base damage, like Vladof Tasers. Can be cosy for cycling Blood Shot in mobbing.

Passives to target:

Damage: Kinetic Damage. Skill Damage. All Damage.

Consistency: Skill Crit Chance. Gun Crit Chance. Status Effect Chance.

Great but not BIS: Gun Damage. Status Damage. Crit Damage. Weapon Type Damage. AS Duration.

Repkit:

Order Repkit With AMP and Enrage for maximum 1 shot potential. Order manufacturer is ideal.

Triple Bypass with AMP for spam-ability.

Shield:

Guardian Angel with AMP parts. Best AMP uptime.

Any shield with multiple AMP parts. Caps out at 150%

Ordnance:

Jakobs Grenade The fabled crit knife, look for the 'Penetrator' augment. Helps our Bleed ticks crit. Makes the initial shot more forgive if you miss the crit spot. You can throw multiple to stack the crit chance %.

Enhancement:

Prioritise passives. Gun Damage. Weapon type damage.

Order charge mult if using an Order Weapon is a powerful damage boost.

High Caliber 3 + Skillcraft 2 is my chosen combo for bosses and weapons that benefit from piercing.

Active Fire 3 + Skillcraft 2 for Order Snipers or Ripper Truck


Specialization

Specialization 2A Honed Mind
Specialization 3I Am A Gun
Specialization 4In The Zone

The Best Defense Offers 30% all damage. Double Dips with Bloodletter.

A Honed Mind and I Am A Gun benefits our gun shot that's to Blood Shot.

In the Zone Just a great damage option.

Replace I Am A Gun with Groundbreaker if you want extra damage.

After perks are Acquired. Spec further Specialisation points into a 2:1 ratio into (2) Killer and (1)Brute.

Gameplay

Bossing Gameplay loop.

Repkit -> Action skill -> Swap firing modes to Spread Launcher or One shot item of choice. Shoot for the crit spot.

Repeat if necessary.

Mobbing gameplay loop.

I enjoy a swap to Phase Phamiliar here for aggro relief. Do the above rotation but fire off an Order Kill drone. You can rotate between multiple kill drones for peak mobbing. Otherwise start sniping away with your chosen Sniper. My personal favourite being the Truck. But any Purple Order or Jakobs rifle is good. Boomslang is a good budget choice too. Player choice here.

For VILE ENEMIES you want explosives. Torgue Impact mag on rifle, or Spread launcher will do the job here. Any sniper shots on the glowing wisps will auto crit and trigger Jakobs ricochet.
