Hello there. I will get to the point. Today I went to the Dunar Temple first on normal difficulty where I got no problems. After I completed the first run I went on middle difficulty and well things didnt go well. I am able to damage the first dungeon boss without any problems but whenever his health gets under certain percentage (by my guess 20% or 10%) his health fully restores. I tried to re enter the area but he kept restoring his health every time I brought it low. I have tried to keep the boss in the water pool area and the health was still restored regardless. So I would appreciate any advice or help.
