The Dark One's Tattoo

Produced by a special needle, this magic tattoo symbolizes darkness and corruption.
As an action, you can speak the tattoo’s command word, hexing yourself. While hexed in this way, you take 1d6 necrotic damage whenever you hit a creature with an attack for the next minute. The target of your attack takes necrotic damage equal to three times the necrotic damage your received from this hex. Once used, this tattoo can’t be used again until you finish a short or long rest.
Each time this tattoo’s effect is activated, it grows in size.
