I hate these levels more than anything in the game, and I have no way to effectively approach them with my arsenal right now.
The main problem is dealing with the mini-mobs. I've tried my main weapons, Glacius and Iron Slug on them, but they just don't cut it against any of the three types of monsters.
I've heard a few times that bombs are the best way to go in Compounds, so those are mostly what I'm looking at. The only 5* bomb I have is Dark Retribution, but that doesn't have the CC I'm looking for. Here's what I've been looking at:
Big Angry Bomb: Huge AoE, Stun, knockback. Works in any level regardless of status or enemy type. Hard to set up and use.
Irontech Destroyer: See above.
Shivermist or Voltaic Tempest: Good CC, but enemies can still get in the way if they aren't killed with an extra weapon. Useless in levels with the wrong status, but best to use against Scarabs.
Graviton Vortex: See above, minus status.
Dark Matter Bomb: Obviously know it's infamously bad, but has decent AoE, works in any Dust Bunny/Gel Drop level no matter what status. Useless for Scarabs.
Shocking Salt Bomb: See above, but doesn't work well in Shock levels.
Scarabs are the lowest priority to kill since I run into them the least. Dark Briar Barrage is a no-go because it's useless against Gel Drops, and seems like it would be too annoying to use against Dust Bunnies or Scarabs to be worthwhile. Electron Vortex is off the table since it takes so many PvP games to get.
Feel free to suggest anything I didn't think of.
Compounds are the worst for sure, but if there's one thing you need to make sure you have, it's charge time reduction, chaos set can make your life easier.
Jelly compounds: These ones for me are the easiest, I'd just get an acheron or obsidian edge and hang back and charge slice them as they come towards me, you might take a bit of damage as you're lunging forward with the charge, but it's negligible.
Beast Compounds: I'd just get a dark briar barrage and spam it to hell, kiting the dust bunnies as it chips away at their health.
Scarab Compounds: These are probably the most difficult to deal with, but there are a variety of ways to deal with em. You can shivermist them and pick them off one by one. You can also do something similar to the jelly method, where you just use a combuster or voltedge to charge slice em as theyre coming towards you. Glacius isn't preferable because it locks them in place, thus preventing them to ride the wave and take more damage. Ash of Agni can be pretty good here too, kiting them as the fire burns them away.
Methods that apply to all : You can get a nitronome ( the best normal bomb in my opinion ), and just spam it, it'll cause knockback, but that's what's good about it, it's a very defensive and versatile bomb (more so than big angry bomb, which has horrendous movement speed while charging and slower charge time ), ensuring that they'll stay away from you. However, this method might take a while to kill them all. You can also use ash of agni, but as it's elemental, it won't do well against beasts.
You can also get an electron vortex and sword away at the singularity with enemies inside, it's a more efficient, but could be riskier method, as grouping them together might be a challenge.
