I just beat Pyro Pete the Invincible for the first time.
It’s not as good as it sounds. It was my fifth try or so, and he got stuck on the ledge between the pillars. I sniped at him as best I could from the other side of the arena, between the bars of one of the metal structures on the floor. Somehow he hit me with novas four times anyway. I was using Maya, so it wasn’t too tough to clean up the rats that emerged when I washed the ow off. Anyway, it took me probably fifteen minutes to finally put an end to Pete, at which point he lootsploded all over the ledge. I couldn’t reach much of it.
I was able to reach 11 seraph crystals, which was nice. At that rate, though, it’ll take me nine more tries - over two hours - to buy a typical item from a seraph vendor (an Antagonist, say). Is killing Pete the easiest way to accumulate crystals, or am I missing another way?
