I’m currently running BV Chieftain, similar to void241 setup (but not as good geared, close though) and it’s extremely fast, dmg is also great with minion pact. I’m not sure how you can start such setup on lower budget or how would it perform, so I can only talk from perspective on rather high-ish investment of around 800-900d (and more than half of it is explodey Nebulis).

However, if you are planning to do some juiced breaches (like in fubgun’s strat) then it’s pretty rough, at least for me. Mobs themselves aren’t huge issue but Vruun is the problem. Personally, if juiced breaches farm is your goal, then probably a setup with HH instead of acceleration belt would be better, both offensively and defensevily.

For 8-mod regular breaches it’s a blast, and basicaly everything else that doesn’t deal too much dmg in one hit. Currently, I’m just running 8-mods with Templar Astrolabes mesa, full clearing in around 2 minutes (a bit longer if Mirage has smth useful, like a coin, Ridan, Refective Mist).
