I did, but at 4 levels above the recommended, with full gear, and I used about 6-7 potions, and cured myself about 2-4 times per fight.

This isn't rocket science, people! I do appreciate the challenge, but what if I was level 10, had no potions, and/or wasn't fully equipped? Either the quest should be rebalanced to accommodate for the recommended level, or the recommended level should be fixed to show the actual amount of challenge.
