It was immensely fun

I love Chemists in all shapes and forms, and this one with JJ is one of the best. My approach was piety farming with the original Weytwut in mana form (base form bysseps spam would have been more efficient, but I didn't want to blow a potion in case JJ poisoned me - which would not have been such a big issue due to the extra potion shops, which I totally forgot

), picking up a bunch of health and mana boosts and slowing/moving around every monster in sight.
Once my stats were ridiculous enough I started murdering huge opponents with excessive Bysseps stacking and Cydstep + Weytwut abuse. To save blackspace I quaffed mana potions here and there. Helath wasn't an issue, I dinged on every kill. It's cool that the sub gave a pair of Elven Boots, it made killing the lvl9 warlock at lvl 4 possible.
If that wasn't enough I later found a B2P to combo with my towering health next to MA, so I could have made my character a crazy spellcaster too. I set out to farm piety with slaying mostly magical attack popcorns, and stopped doing it when I found the snake boss. My stats already allowed me to fireball it down with a single ding so stayed at JJ. To spice the run I did take a detour to Taurog and back, this way I could melee down the Iron Man in a similar fashion - with a single ding Warmonger style. Too bad he didn't have better stats, I missed the chance to use health form.
