Weapons:
The newly released Acolyte (preferably at rank X, but any will do) is the best choice to use for this class for farming Geth on Gold.

Gear:
I would suggest Mental Focuser V, that 12% bonus to power damage is good

Strategy:

This build is designed specifically for people who like to farm gold against geth.

It’s quite straightforward. You use the Acolyte to deshield everything. It staggers (short amounts but it helps), completely decimates shields (will take out a prime’s shield in 3-4 hits on gold after charged shots, everything else is instantly deshielded when hit by the acolyte shot), and thus is a very good weapon for stripping away the shields of before you lay on the hurt on those primes. Once the shield is down, you keep hitting the enemies through the walls
with the smash. the electrical evolution for smash will allow for tech burst spam, and will work well with other tech based characters as well (instead of conflicting between biotics and tech, thus interrupting each other’s combos), and smash in general does -alot- of damage as well, and can be spammed very quickly. Smash can travel through walls to hit enemies, so make use of that to always remain in cover but hitting them hard and fast. The key to this build is
utilizing those small spaces to lay on as much damage as you can in the shortest amount of time, or as Kirrahe says “Hold. The. Line.” You can also throw in the heavy melee to cancel smash, but quite franklyyou wont even need to do that, smash will kill everything off so fast.
Dont forget, smash can affect targets at higher/lower levels as well, so you can use that to your advantage to hit enemies that are say, one floor above/below you. Ideally, you want one person to use this build, the rest can be whatever they wish to be to cover the other bigger area- multiple people using this in the same area will result in
blocking, and thus you’d either get each other killed, or waste time and energy otherwise. and as always, good communication is key.

This build can single-handedly take on 2-3 primes at a time and kill them fast, and can hold a choke point solo while your team-mates watch your back from the other entrance.

Here is a video of a gold pug run i did with this build for you to give you an idea what i mean.

N00b Rating: (scale 1-5, 1 is easy for everybody!) 3.5
This build isnt that hard to use, but initially it will take some getting used to. make sure you always know where your enemies are, and know how far your smash can reach out to (that way you can hit them through walls etc). Ensure you always have a way back out (aka, your team-mates are watching your back) and help them out if they get overwhelmed, but dont forget to cover your point as well.
