I really like her abilities but to be completely honest I haven't figured out what kind of a build to go for on her. Damage seems good even if you just spam and spread doom around, #4 is a really good "ohshit" button when you find a large group of enemies that need killing, but her survivability seems a bit low, she doesn't have any damage reduction or even healing abilities by default (and low base armor value as well). She seems overall solid but doesn't really excel in anything and doesn't do anything extraordinarily fun?
I kinda mitigated the low defense with a few blue armor archon shards, as for healing her signature melee weapon can restore health but it seems like bad synergy - her #3 boosts crit weapons but her Dorrclave is a status weapon? So that seems like a trap.
Adaptation, arcane grace and her #3 lifeguard do a lot of heavy lifting but all in all, it doesn't seem as reliable as other frames. Maybe subsuming gloom would help but I'm not sure what to replace, and that's kind of a boring thing to do anyway.
So anyway, any thoughts, how have you been playing Dagath so far?
Here's my 0 forma build, it will likely stay that way for a couple of years as I don't like putting formas into non prime frames.
Her survivability depends on shieldgating and her 3, Arcane Blessing and Equilibrium help a bit too, I tried Arcane Guardian as well but 666 hp is not quite enough in higher level missions.
The playstyle is mostly cast 2 then spam 1 to spread, cast 4 if large groups or if you need armor strip, cast 3 and have it running whenever you have enough energy.
