Djinn-skein

Archmagos Draykavac increases the Ballistic Skill of any unit he joins by +1. In addition, while Archmagos Draykavac is present on the battlefield and not Embarked in a Building or on a unit with the Transport Unit Sub-type and not locked in combat, the controlling player may re-roll any Scatter rolls made (whether as part of a weapon attack or the deployment of a model or unit), as long as Archmagos Draykavac has line of sight to the unit targeted by the attack or the point chosen as the target of the deployment.
