Utilities

GUNS

Lucian's Flank - Easy to use, gains huge amount of crits in no time for maximum uptime of Trooper and Confirmative Reality. Ok Mobbing.

Katagawa's Revenge - Can overlap damage with Ordnance weapon to mass proc Critical Funding in boss fights. Also good for the above. Use on Shock mode.

HEAVY ORDNANCES

Jetsetter - The primary bossing option. Very high DPS.

Disc Jockey - The primary mobbing option. Mass clear, no effort.

Vladof Purple 'OOTKA' - A good easy access all rounder.

Bottled Lightning - Funny mobbing option. Good for Origo or Phase 1 Bloomreaper.

Purple Torgues - Both Rocket Sockets and Honey Bunches. RS for a general use all rounder. And HB for burst bossing DPS. Good for Bloomreaper main phase pre Jetsetter.

CLASS MOD

Trooper duh.. Focus Refraction for skills. Then Gun damage / fire rate / movement speed for passives.

EHANCEMENT

Main stat doesn't matter (Jakobs Bounce pass if you must)

Stats to prioritise:

GUN EQUIP SPEED!!!!1!!

Gun Damage

Gun Critical hit damage

Generic Gun bonuses

SHIELD

AMP! It's always AMP. AMP is our overlord. Biggest AMP% you can find.

For perfectionists it's ofc Watts 4 Dinner with 150% AMP.

REPKIT

Whatever your heart desires.

Kill Spring for passive healing.

War Paint for burst DPS.

Most Ordnances will want Deadeye - 3. However Rocket Socket and Ootka may want High Caliber 3 to pierce through targets and hit the ground behind them.

Specialization

Specialization 1Fragmentation Payload

Specialization 2Full Spectrum Arsenal

Specialization 3Riddle You This

Specialization 4The Best Defense

Fragmentation Payload is beyond ridiculous. Giving at 50% bonus to all of your Critical hit bonuses within Skill Trees.

Because of this focus all excess points into the Killer tree and Brute at a 2:1 ratio.

Gameplay

Point n Shoot not much too it. When your Action skill ends use Lucian's Flank or Katagawa's Revenge on enemy crits to get all your cooldowns back. Remember casting your action skill will CANCEL Ordnance so Action skill first. Left over Nuclear Winter will help getting free crits for Trooper and Confirmative Reality.

If you want more in Ordnance ammo sustain, notably with the Bottled Lightning. Fire Katagawa's Revenge several times into the target before activating and firing off your Ordnance. The lingering teslas from KR will mass proc Critical Funding to sustain ammo freely.

BLOOMREAPER

Use Bottled Lightning or any explosive HOrdnance for phase 1. Lucian's Flank is effective at cleaning up any flying Vile Ordonites.

Phase 2 Jetsetter or a fire Honey Bunches will be the way to go. Fire Dead Spread is lower damage but easier to use than Honey Bunches. HB is also a pain to use without GUN EQUIP SPEED on enhancement so make sure you have that.
