Arcane Bullet [AoD]

You produce a gleaming crystal of arcane energy in your hand, which then hurtles toward a target within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 force damage, and you gain a +1 bonus to spell attack rolls made against the target. This bonus stacks up to a maximum of +3, and disappears when you end your turn without casting this cantrip.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
