Nearby JJ at the start was a relief (since I didn't prep it).
Used Alpheesik, Burndayraz and WeytWhut for the early higher kills. After snagging an Elven Boots and finding the shop with the Platemail, I decided to buy it early. The slow strike did mess with using of WeytWhut, but luckily the resists + DR from the boots and the platemail, together with finding Cydstepp made higher level kills possible.
Looking back, I think buying the Platemail fairly early was a good decision as it helped to save tiles and allowed for higher level kills (the boots was also pretty useful with the many magic enemies around).
Cut to the end - With fully explored map, converted to TT with 100 piety before starting on Evolvia. Wanted to leave CA for the end after 10, and TT was much more useful both for getting the level-ups and his potions. 4 compression scrolls meant a pretty solid inventory I had going into the fight. Downed Evolvia, mopped up until I hit 10 exactly, then convert to EM just for Plantation, then converted back to JJ after 2 shots of Clearance (needed that to declog). Whupaz and both bars unloaded, before desecrating EM and TT for CA. Fully refilled, finished Frank and the few mobs remaining.
[Edit: The Whupaz and Dodge/Reflex, used up mana bar, etc. happened straight after converting to EM. So the 2 shots of Clearance also gave me plenty of HP with Halpmeh to put in more damage on Frank]
