Well, I found that the undeads (level 69-70) in the dead scar (in the new island "Isle of Quel'Danas") do extremely low damage (about 2-3) and have normal hp.
You can find them at the start of the Dead Scar around 52.86
The point is, you can increase your weapon skills on these mobs or use this to test things which need low damage on you and etc![]()
here is an image
I hope it helps
