This spell can only be cast on weapons. The caster must hold the weapon for the duration of the ritual, speaking in a whisper to the weapon. Usually this whisper is a description of its owner or of a specific personality trait that a prospective owner must have to claim the weapon. Once enchanted, the weapon must be attuned to its owner before the enchantment will take effect for that person. Before attunement, the caster must choose wisely where he places the weapon, because it will be immovable until its proper owner claims it. Attunement takes 1 Action, and can be done from afar if the caster was specific enough in their description of the intended owner.

If it is not already, the weapon becomes a magic weapon. If the weapon doesn't already have the thrown property, It gains the thrown property as part of this spell with a normal range of 180 feet and a long range of 360 feet, and gains a +2 bonus to attack rolls. After a ranged attack is made with the weapon it immediately returns to the wielder’s hand, whether the attack hit or missed; if the owner is teleported or moves while the weapon is being thrown, the weapon will change course and seek the owner's hand until it is found. If the weapon is put down by its owner, it is immovable by anyone else and remains in place (much like immovable rod) until called (as a bonus action) by its owner. Once called, the weapon will fly as directly as possible to the hand of its owner no matter where the owner is, even smashing through objects in its path.
