Wondrous Item

Rare Requires Attunement

Description

This whistle has been cast out of aquastone in an adamantine mold. What is most unnerving about this whistle is the bead set inside it; it's made of the tooth of a truly terrifying creature of the great depths, carved and sanded down to the size of a marble. When blown, the whistler can attempt to enslave a mind to their will for a short time.

When you blow this whistle you may choose one target (beast or humanoid) within 30 feet of you that can also hear you, whose CR is no more than one quarter of your character's level (rounded down). The target must succeed on a DC 14 Wisdom saving throw or be magically charmed by you for up to 1 hour or until it is on a different plane of existence than you. The charmed target is under your control and can't take reactions.

Whenever the charmed target takes damage, the target can repeat the saving throw but does so with disadvantage. It may attempt to do so once (without disadvantage) when it is at least 1 mile away from you. On a success, the enslavement ends.

Once this property is used, it can't be used again until the next dawn.
