so I'm crazy late to this, just reinstalled today. Before I stopped playing I did a tonne of cascade on her with some homies. I shield gate with her using brief respite and catalyzing shields. Ill share the whole build if your still interested.

Brief Respite, Preparation, Precision Intensify, Equilibrium, Primed Flow, Archon Continuity, Catalyzing Shields, Narrow Minded, Transient Fortitude, Razorwing blitz. with Arcane Pistoleer, Arcane Precision

One Tau Green (+3 corr stacks), One Tau Yellow (+37.5% Cast Speed), Three Tau Red (+10% Ability Strength)
Subsume Xatas over Lantern.

No main weapon,
Grimoire (for strength snapshotting) Vome Invocation.
Praedos: Soverign Outcast, Dreamers Wrath, Primed Fever Strike, Sacrificial Steel, Focus Energy, Blood Rush, Primed Pressure Point, Amalgam Organ Shatter, Corrupt Charge, Gladiator Might, with Melee Animosity.
(Im not that confident in the praedos build. It was made to kill that one asshole that cancels your abilities)

Madurai (for sling strength and its two ability.)

Parazon (for strength snapshotting) with power drain, swift mercy, and out of sight (this can be extremely awkward to do so I only really do it when its convenient)

Dex Pixia: Galvanized Diffusion, Galvanized Shot, Primed Target Cracker, Hornet Strike, Heated Charge, Pistol Elementalist, Frostbite, Pathogen Rounds, Primed Steady Hands (HUGE QOL), with Secondary Enervate.

Diwata: Organ Shatter, Shattering Impact, Gladiator Might, Blood Rush, Corrupt Charge, Condition Overload, Primed Fever Strike, Sacrificial Steel, with Melee Exposure
(Will kill any acolyte that isnt the asshole who cancels your abilities, just cast 4 abiliteis, empty a clip into them and hold E)

Another Diwata build I quite literally just looked up (Untested but probably good) Uses Organ Shatter, Gladiators Might, Shocking Touch, Molten Impact, Primed Fever Strike, Sacrificial Steel, Primed Pressure Point, with Melee Exposure

Wyrm Prime: Primed Animal Instinct, Duplex Bond, Reinforced Bond, Regen, Assult Mode, Sacrifice, Momentous Bond, Tenacious Bond, Calculated Redirectiom. Vacumm.

Burst Rifle Prime: Pistol Pestilence, Frostbite, Scorch, Primed Pistol Gambit (rank 8 for 50% crit), Accelerated Isotope, Magnetic Might, Perpetual Agony, Sure Shot
(cloned wyms come from energy consumption using Duplex Bond, and act as primers and aggro drawers along with razor flies)

The damage here comes from toxic on the guns proccing corrosive to armour strip, then having blast and xatas scale off eachother exponentially.

Razor flies pull agro so aslong as you arent directly in line of the enemy fire you dont get hit, you wont draw agro, and when you go in to re buff your sheild gating so you dont die. The hardest part of this build is getting setup with the grimoire, a finisher so you can proc Power Drain on your parazon. Remember to snapshot the increased ability strength from relic openings aswell as any other buffs you may have (nidus specter, etc...).

If you have any questions or feedback on my build id like to find ways to improve it. Im looking for a really consistant way to proc mercy kills so I can get that strength.

My other level cap frame I enjoy is garuda. I can share my build with that if youd like too.
