Immobilize (status)

Don't Move, also known as Immobilize or Bound, is a recurring status effect. This status prevents the affected character from moving, meaning they can be easily targeted by enemies. They can still perfom actions though.

Final Fantasy XI
Bound is a status effect that prohibits movement. There are any number of abilities that could result in a player or creature becoming bound, but the most direct manner of getting caught would be the black magic spell bind or a ranger's ability shadowbind. Generally speaking, bind does not prohibit movement for very long, and while the creature cannot move, he can be moved by various effects with knock-back. Even being moved in this manner does not break the status effect though.
