Arcane Crepuscular
Arcane Impetus
This build is only 3 forma, the vazarin polarity in the [Mind Freak] spot is based on my other configs.
This build can also be used on [Nyx] since she has an augment for armor stripping, making your mind controlled ally kill enemies easier. The only downside is that you cannot use Arcane Crepuscular for the easy strength.
The most optimal way to buff your target as much as possible is to:
1. cast [Damage Decoy] (preferably on a melee enemy because they go nuts with the buffs, or at least on something strong)
2. cast mind control immediately after
3. hit your mind contolled target really hard immediately after that to further proc mind control's damage increase
4. watch it kill a bunch of enemies
5. when mind control is about to run out, [Safeguard Switch] the target and repeat the process
