1st-level Spell: Seeking Projectile

Aspetheurgy (Transmutation)

You touch a piece of ammunition or a weapon with the thrown property and imbue it with a seeking spell. The next time the item is used for a ranged attack, the attacker can add your spellcasting modifier to the d20 result. If that makes the value on the die a 20 or higher, the attack scores a critical hit. The spell ends after one attack.
