In the description, Hand of Nostrum at Level 3 is supposed to add 3 Healing Beams. So the Witch Doctor is supposed to be casting 4 Beams. (At Level 2, it adds 2 Healing Beams, and the Witch Doctor is casting 3 Healing Beams on heal.)
But in game, I am only seeing 3 Healing Beams at Skill Level 3. Has there been any changes to the how this skill works?
