Yes. Get an Inflammable or Alkaline prefix if possible, Alkaline is best as his first nova will always be corrosive unless you strip his shield before his first nova, the he will always pulse double novas. Still, one DoT is better than two, Grounded prefixes have no place against Pete unless it’s all you have.
Most videos you’ll see on YT show people hiding behind the scaffolding to avoid the novas, I doubt this was intentional and personally view it as an exploit (no offense Derch) so yes, unless I fail to strip his shield before the first nova as it’s a corrosive one which I’m immune to (at least the DoT, not the impact)
As many as he can dish out, though you typically want to put him down quickly, the novas aren’t the problem it’s the increasing levels of the adds. I run SS on my Maya, when I shed the DoT I PL a spiderant when Pete is nearby so he gets slagged by Ruin and to activate Wreck, CR clears the adds pretty quickly. I usually kill him in 2-3 novas, the choreographed one when his shield is down and one more after that, sometimes a spiderant hits and strips my shield so it may take one more nova, but with Ward it’s usually back up quickly and I can take him down in two novas even after a hit.
Try to avoid spawning the rats as they’ll shoot and disrupt your Bee, though the adds are low level for the first few spawns so a Quasar usually kills them all if you’re not running SS or if SS decides to hit Pete instead. You don’t even need a Chain Lightning or Grog Nozzle to kill him though it never hurts to have a safety net, just run a Grog if you need but keep a Quasar for CC and to kill adds. I fight Aria the exact same way I fight Pete, in fact I should credit Pete for lending me the simply strategy, just gradually walk backwards and fire away, when his flamethrowers get too close stop ADS so you can move away faster and strafe-jump away from his, um, globs? Whatever those land mine things are. It’s a pretty systematic fight, he does have a lot of health but shock wears down his shield quickly and his crit is hard to hit, plus his attacks aren’t really threatening so he goes down a lot easier than he probably should, keeping your Bee up isn’t hard once you learn to anticipate his predictable attacks and once you’ve done it a few times he’ll never give you trouble again.
