Immobilize

Immobilize prevents a unit from moving and from casting certain abilities that move the unit, although by itself it does not prevent attacking or using non-movement abilities and items. Some sources of Immobilize also prevent turning as well.

Immobilize will also prevent units from being targeted by a Tablet of Command or  Rally's Compel as well.
