If rendered unconscious during a fight, either by loss of HP or a sleep spell, Ireena can project her astral form from her body, to continue the fight. Her body is left behind in a state of suspended animation; it has the Unconscious condition, doesn’t need food or air, and doesn’t age.
this spell is specific to Ireena Indirovich, or any other Vistani that share her bloodline
Ireena's astral form resembles its body in almost every way, replicating its game statistics and possessions. The principal difference is the addition of a silvery cord that trails from between the shoulder blades of the astral form. The cord fades from view after 1 foot. If the cord is cut—which happens only when an effect states that it does so—the target’s body and astral form both die.
Any damage or other effects that apply to an astral form have no effect on the Ireena's body and vice versa. If her body or astral form drops to 0 Hit Points, the spell ends for that target. The spell ends for all the targets if you take a Magic action to dismiss it.
Ireena's astral form can travel through the Astral Plane. The moment her astral form leaves that plane, Ireena's body and possessions travel along the silver cord, causing Ireena to re-enter her body on the new plane.
In her Astral form, Ireena has the same conditions and abilities as a Ghost. However, she can only possess inanimate objects. If she is possessing a weapon that is being held by someone, she can increase or decrease their hit rolls, or add a necrotic effect.
