I never did the older Halloween quests. Today I tried the one from Conarch Village. I got all the way to Kill the spirt beast and failed. After 30 minutes I ran out of pots and he was at 100%. I tried avoiding the light circles. Standing in the light circles. Fighting in the "shade". Fighting in the moonlight. In all cases, he regenerates heath faster than I can dish it out. What is the trick?
Thanks
