Hello there,
I was on the PTR and i discovered a nice new bug with the Priest spell Levitate.
If you get stuck on a wall (even an invisible one), so that you can autowalk without moving, then you can use Levitate and you will climb that wall simply by running forward.
Also if you are against a wall, you can Levitate and run forward+strafe, that will allow you to strafe the wall and to stay at the sem altitude, even if there is nothing to hold you
Edited, sorry for the rep beg, that smiley has driven me into mistake
