[[Jailer]] is a [[Boss Modifier]] in Diablo III. [[Boss]]es and [[Champion]]s (and [[Elite]]s) who possess this ability can "jail" characters and their pets for a short period of time. While jailed an orange circle of light appears around the target, and they are held in that location until the jail dissipates.

Jailed targets can still fight, hit enemies, cast spells, drink potions, etc. They just cannot move, though some skills will allow an escape from the jail. This boss property is also possessed by a good number of [[Elite]]s, most notably (and appropriately) by [[The Warden]].
