Spoilered for size, but.
I think my witch doctor just died. Pretty sure the witch doctor died. Doc totally died. In a fire. Dead as all hell.

So far as the lasers go, I
want to say you can go under or over them, if you have room to dash the same direction they're going and pull down/up as hard as possible, without needing to teleport. 'Bout the best I can offer for that one, though. I may be giving my solid try to dodging, generally, but I also said to hell with it a long ways back and set to freezing my HP. Mostly dealt with the lasers by ramming the lasers, heh.
... alternately, if you can kill it fast enough, either the lasers don't come or there's few enough you can tank what does if you can't dodge it. As harped on repeatedly, a white dwarf setup can do it. Probably best with an elemental disk for the first kill, but a molten whatsit (the providence drop) or shadow dagger can manage.
But yeah, dwarf set bonus + that disk and optionally (double) throwing book (probably the collection and the best single one) will basically straight up
delete the devourer. Iirc it can spike into six digit DPS for that fight and maintain 30k+ per second with ease. The friggin' thing only has at most a million HP per notable phase. Can potentially kill it so fast the invincibility that kicks in when the smaller worm comes in
doesn't have time to activate. It's faintly absurd. And beautiful.
And performance wrecking, ehehe.The combo's not as strong versus small(er, at least segment wise) enemies (mind you, it still wrecks several different kinds of face), but the dwarf set will just
demolish worm enemies, the bigger the better, and with it the elemental disk in particular is just a barrel full of chainsaw monkeys hopped up on PCP and trying to hump
every square inch of the boss. Just make sure it's the throwing version of the disk, heh.
E: Though now that I check, the second worm doesn't actually make the DoG invincible, just hides its health bar. Still, the dwarf/disk combo can kill it faster than the obfuscation goes active, so... yeah.
