That was waaaaaaaaaay to close for my comfort today. Wish I'd have taken the Health Pendant; couldn't soak up a hit of the last boss in the end, and I was out of blackspace so I couldn't level any further. Also had to use a reflex potion to get rid of Herp/Derp?/magic immune guy via first strike.
When I was left with the boss, I used bloodpools to refill my health, and then used a shop for overheal. Blast with a fireball, rinse and repeat. The last hit was dealt via bloodswell, and I had thankfully one popcorn left to get rid of the curse... but man, that was close. Lot of mismanagement going on, my rats gotten rusty.
Honestly, I kinda wish we'd get a thief run soon.
