Some examples of how to stun wraiths/deal with it if they don't stun immediately. 1st vid is some backups and 2nd vid has some examples of what you're ideally aiming to do. Don't try and do 2 at once unless you have specific setups for it. Their attack arc is a little delayed so you can manip it very easily. You want them to be above/below you.
The first part of the first clip is extremely important to know. You can simply react to if they didn't get stunned, jump over the attack, and insta needolin again. It will basically always work if you are quick with the needolin.
