My attempt at a vex reaper build.
So yes, this build obviously isn't made for UVHM 5 or 6. I still tried my best, and this is what I came up with. Bosses are still just haruspex and lucky reverburnation procs.
Mobbing is pretty decent, and the ordinite generators are honestly not that bad. I just wish gearbox would listen to us and give us actual meaningful buffs instead of uncalled for nerfs and 6% damage buffs. Mayhem scaling would be great, but at this point, I'm not expecting much.
For gear, I use an illusionist with 5/5 on ancient rites. A reverburnations class mod would probably be better, but I can't test that as I don't have one yet. Nade is between a slippy or crit knife, your choice. Shield is kinda whatever as well. I use a timekeeper's new shield for survivability. For raw damage, you can use a heavyweight. Enhancement doesn't matter so long as it has good firmware. The repkit I use is a pacemaker for more survivability. You need a mantra for damage, so long as it rolls good elements, it's fine. Mine doesn't have a ripper part, and it's still good.
Firmware is 2 action fist and 3 reel big fist. Last slot is up to you, but I use rubber band man. Skill craft is really good as well. If you go that route, use 2 action fist and 3 skill craft.
Specializations is groundbreaker, a honed mind, and your choice for the other 2.
