Aetheric Sentry

You conjure an aetheric sentry that deals 2d8 damage to all targets within 30 feet of you. Only one sentry may exist at a time.

Delayed Cast: By using a spell slot to imbue a spell into a bullet, you can use the sentry to fire the spell, dealing both the spell's damage and the sentries damage.

Higher level: Each 3rd level higher than base provides an extra base 1d8 damage. At 7th level, it gains flat +5 damage. At 9th level, it gains 2d8.
