The last judge is great

So I'm at the end of act 1 and just started the last judge today. I gotta say I'm having a blast. Yeah I've been getting curb stomped, but this boss is badass. I hated savage beastfly, but this guy is great (for now). Anyway, I was using reapers crest but switched to wanderers crest because it's significantly faster. Only downside is that I don't have all the slots unlocked yet. Feel free to share any tips y'all have to make this fight easy. Yes, I have watched a bunch of vids on it and I do think I'll get it sooner rather than later.
