(add more information about the dungeon layout and enemies)
You worship Taurog.
The boss in this challenge is Scalespit, a dragon with 97 attack, 412hp, magical attack, mana burn and 75% magic resist.
The alchemist and blacksmith.
Prep a Compression Seal. Explore a bit to find some glyphs to convert, get Skullpicker. Use that to win the earlygame forever. Accrue Taurog's gear. Try to use HALPMEH when you've just gotten another piece of Taurog's gear so as to maximize your piety gain and leverage your Holy Work class feature. Don't be afraid to use mana potions to spike high level fights, you're not going to be needing them for the boss. Good items to pick up are Platemail, Elven Boots, and Soul Orb. Platemail allows you to start attacking the boss at level six, and Elven Boots allows you to throw two BURNDAYRAZ even with Taurog's gear. With a midfight levelup, health potions, and Taurog's death protections, you should easily be able to take down the boss.
