You're mistaken. Multi-hit refers to an attack which deals damage in an area multiple times, like Nasus E or Rumble Q.

DoT refers to abilities which apply a debuff to the enemy which damages them periodically, like swain E or malz E.

The primary difference is you can move out of a multi-hit spell, while a DoT spell is garenteed to deal its maximum damage.

Either way, I know for a fact Vladimir's E slows for 40%, which you can test.
