This is my Farming [Nekros] that is definitely way too expensive. But who cares, i just fucking love [Nekros] so I dont mind spending an Umbra Forma.
This build is supposed to be played in SP Survival missions with a farming [Khora] ([Hydroid] also works, just not as good because of CC).
You will always have Enough energy, its pretty much impossible to die if you stay close to the camping spot. Remember to bring a good single target weapon like the [Kuva Zarr] to get rid of the Disciples.

Basically:
Cast 1 if you have Energy left and want some extra damage
Cast 2 for crowd control if yor are about to get overwhelmed (Not recommended to use in Survival)
Cast 3 and always Keep it up for Extra Drops, also to enable [Health Conversion] and [Equilibrium] to proc (Avoid Healer Frames for better Synergy)
Cast 4 for fun if you have the Energy

Compatible with Way too fucking expensive Nekros Battle/Endurance Build | Config B

Have Fun!
