Witch hut: nothing special
Grabbed god of war early and started beating on higher level magic users, grabbed the gold gloves early on and converted them when I needed room. Also bought a vampiric blade, and converted that when I needed space. Started beating down the boss at level 7. Finished at level 8. Grabbed every piece of god of war's equipment except breast plate. Switched to tiki around that point (this wasn't really needed, all I did get a potion of dodge out of it). HIt level 10 at the same time I got to the real boss, ended up burning a lot of potions with those last 2 poison physical dragons. Still had a good number of unrevealed tiles at the end, and I probably could have squeezed one 1 final health potion.
Over all not too terribly hard with a berserker due to the amount of magic damage going out (and both level 10 bosses are magic users). I am curious if you can skip those lesser dragons by using sight + teleport glyph.
