Remains in play. Target a friendly or enemy unit within 24", even if engaged in combat. The unit is Unbreakable for as long as the spell is in effect. This replaces the Instability rules for Daemons. The spell remains in play until the caster decides to end it (which he can do at any time), it is dispelled, the Sorcerer attempts to cast another spell or the caster is killed. If a unit that is fleeing, it automatically and immediately rallies.
