Seeking Projectile

A spell by KibblesTasty 1st-level transmutation (Artificer)

Casting Time: 1 action

Range: Touch

Components: V, S

Duration: Concentration, up to 10 minutes

You touch a piece of ammunition or weapon with the thrown property imbuing it with the property of seeking its target. When an ranged attack roll is made with that weapon, the attack roll can add your spell casting modifier to the value on the dice. If that makes the value on the die a 20 or more, the attack is a critical hit as if a 20 was rolled. After making the attack roll, the spell ends.
