Well, not deliberately going for it but currently top for both XP and Piety,

Pretty certain Tinker can beat these scores with her hands tied behind her back,

As can be seen from attached results screen, there were many things I have done that were "not optimal" for maxing XP - taking Blood Curse at level 2, feeding lots of health potions to Dracul to grab his boons early (and because there were too many undead around) where the potions could have been used for more XP with Alchemist Pact, starting to use Imawal quite late, and lastly for converting back to Dracul in the end (cost me some XP with several Health potions that I had no more piety left for the Alchemist Pact bonus. Dracul dislikes health potions and each potion takes back 9 piety rather than the normal 4 just from the Pact).
