Best for eidolons IMO. Very nice quality of life and is a big beefy boy.

DO NOT USE COOLANT LEAK - if you slow the eidolon with this.....yea. Big no no.
DO NOT USE VACUME - Please, your VS will complain and you will be griefing.
If you don't want to use forma, just make sure you have [Negate] on there and some survival mods. Or don't use a companion that works too (thought I find finding voms easier with [Animal Instinct])

DPS Volt Build
Rubico Prime Build
Pandero Prime Build
Vastilok - [Sarpa] and [Redeemer] are similar
Itzal
Wyrm Gun - lol
