@mpetruzz Does a caster have to have LOS to their Spiritual Weapon for it to attack? If not, what if he can’t see target? The spell doesn't require you to see its target. It follows the normal rules for attacking a target you can't see. @mikemearls

@mpetruzz caster could leave the room and leave a spiritual weapon floating in the doorway for a minute w/ disadv to hit? Yes, assuming there's actually something there to hit. The weapon could be swinging at the air. @mikemearls
