What you were expecting to happen, and what actually happened?
Wight lifestealing doesn’t work, he does the damage but wight isn’t recieve the life stolen. What are the steps to make it happen again?
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
Pre-patch there was also an issue where he would gain the full amount if life-stealing from a barriered enemy (rather than 0, as no damage was actually dealt). Not sure if this was intentional or not. Obviously this is not currently testable, but may be another consequence of how his spell works.
