The Evil Zombie
Witch and Bazaar.
There are no Mana Boosters or Potions in this dungeon. There are three extra Attack boosters and three extra Healing Potions instead.
Golem: Magic Resist 50%
Zombie: Bloodless, Undead
The boss is Mister Evil ( Zombie icon, Attack 105, Health 2220, Undead, Bloodless).
The recommended race is the Halfling. Mister Evil has a lot of health, and does enough damage to prevent most characters from surviving two hits. Playing as a Halfling Priest allows for 6+ extra Health Potions, which should be just enough to defeat the boss as of level 8 or so. The challenge could also be possible with a Dwarf, however this character needs to build up at least 211 Health (or sport physical resistance) to survive two hits from the boss, to compensate for the lower amount of Health Potions available. Since - barring a lucky store selection - this requires Level 9 or 10, while the Halfling can win at Level 8 or 9, this makes the Dwarf play riskier.
