Use [Primed Regen] if you have it.

Use with [Sweeper Prime] (fire rate, punch through) or Helstrum (fire rate, gas procs) to tag as many enemies as possible for Energy Generator and Synth Deconstruct.

Can use medi-ray instead of animal instinct if you find [Medi-Ray] useful. This will also save you a forma.

[Repair Kit] is probably better than more shields, but if it comes down those mods making the difference, your little buddy is probably toast.
