HORBA Amon

A build by user AncientRune that you can view the full details of here.

I have modified it to have more gun DPS just by my addition of the enhancement and chosen weapons, that way if you get tired of the infinite rockets (or, more likely, you mess up and have to wait for a recharge due to potato aim) you have enough firepower for backup.

Fairly straightforward, use rocket launcher, shoot badguys, profit. As long as you're landing shots you shouldn't have an ammo consumption issue.

I've noticed though that the shouldered rocket gives you a bit of a blind spot on the right side so keep an eye on your radar for enemies hiding in that spot.

Use your shield abilities for some cover to keep your amp shield up longer whenever you can.

The wombo combo does wombo combo things and rocks, especially with the cryo damage boosts built into this build.

Birt's Bees is a solid fallback for those annoying elemental eater enemies who ignore your cryo.

The other two weapons are, honestly, wholly replaceable. They're kinda fun though, give em a shot!

There's another good weapon to use in your backpack, better for bossing from what I've read.

I've adjusted the firmware so that each heavy will give you the appropriate firmware boosts when equipped.

Specializations are maxed, gear is god-rolled (or close to it) for this build, campaign complete. UVH 6 unlocked.

You'll need to convert the .yaml to a .sav

There's a tool on nexus for it that's popular or if you're lazy like me you can use the BL4 Save Editor that's available.
