Leave them dry in the their corpses.
I guarantee that this build will surely drain the lives of your enemies.
Optionals:
You may use non-Primed and non-Umbra mods.
My thoughts:
Gloom is here to mimic Sonic Scream which drains the health of nearby enemies. You can place Gloom in Ripline or Paralysis but I recommend replacing Paralysis. [Amar's Anguish] and Hatred serve as mimicry to [Ash]'s Teleport, it is a good alternative for Ripline if you want to surprise and sneak up on enemies.
You can use any build with her kitty claws.
