My goodness that was basically embarrassingly easy. The sad part was I perfectly foretold it.
Second boss was Bleaty and I just ended up face tanking him, because I had the HP and resists to do it (220hp after Chaos Avatar and I could have converted BURNDAYRAZ to go for 230 had it actually been necessary.) If I hadn't drank a mana potion at L3 for leverage, I could have gotten Feeling Parched too.
Quick side note/brag: As much as I defend JJ in general, you really have to take him as a Paladin to really understand why he can be worth the prep, even at the cost of an inventory slot; I ended that with 45 piety to spare and could have gotten a second mana boost. 36 for Petition, you can easily get at LEAST three health/mana boosts (so long as it's some combination of 2/1) usually by level five, and 64 piety Chaos Avatar leaves enough left over that you might have a decent Last Chance or getting the second health/mana boost you didn't earlier. I could have used potions against Bleaty instead of Chaos Avatar and still won. JJ is really awesome when he's not double-weakening you at L1.
