How do you kill a healer. I just whack away and he keeps healing himself. I took 2 try's at him, both lasting about 10 minutes, to no avail. What's the trick?
When he starts to heal you will see red lines around him you will want to use interrupt then heavy attack to knock him to the ground. This is pretty much the same for any casted ability from an NPC. You can do this by holding down block and pressing the left mouse button.
