Mindslayers can also reach negative movespeed. They do this by wearing two chronomancer staves, nimble armor, and invigorating boots of speed. They then activate 5/5 quick as thought, which (at least) doubles that 60% movement reduction from kit, getting a net 120% reduction, dropping them to -.2 MS.
Bits and pieces of that kit can be swapped around to hit "merely" 0 MS, and a higher % boost from QaT (This was tested with a base 60 will debug character.) loosens up requirements and further reduces movement speed.
Please don't knock QaT for this. It doesn't deserve it
