I was testing out the MF ult stacking bug and I saw that the damage indicator was for magic dmg not physical dmg when ult was used on top of e. It can be just a visual issue, i cant confirm if the ult has been converted to magic damage. Also, by cancelling MF's ult repeatedly by moving right after casting ult, it will fire multiple ults in all directions.
