La Luz del Juicio hace 6 puntos de daño a la criatura objetivo. Destruye hasta un Equipo anexado a esa criatura.
You don't choose the Equipment to destroy until Light of Judgment is resolving.
Light of Judgment can target a creature that has no Equipment attached to it.
If the target creature is an illegal target when Light of Judgment tries to resolve, it won't resolve and none of its effects will happen. You won't destroy any Equipment.
