I am in Act 1 and killed the skeleton mages before you get to the three laughing skeletons hanging on the wooden poles. I found that at this point my endurance slowly went away and I was walking very, very slowly. I went down and even did the samuel's chamber part where you get the first battlefield key and touch the six statues to move onto the next area.
I went to the battlefield and slept. I took potions,etc, etc. I am walking painfully slow and cant seem to get back to my normal walking speed.
Anyone else encounter this???
