Coin toss

You take a gold coin and strike it with your weapon, sending it hurtling toward a foe. The coin is consumed and destroyed as part of the attack. On a hit, the target takes 1d10 piercing damage. The spell’s power is doubled if ranged damage is applied to the coin as a reaction by another party member.

You can use coins created by the spell Taboo: More Than One Kind as material components.

Cantrip Upgrade. The damage increases by 1d10 when you reach levels 4 (2d10), 10 (3d10), and 17 (4d10).
