Baneful Spirit

You call forth a nature spirit to inspire a feeling of doom in your enemies. The intangible spirit appears in a space that is a 5-foot cube you can see within range. The spirit looks like a transparent beast or fey (your choice).

Until the spell ends, whenever the spirit's space overlaps with the space of another creature, you can force the creature to make a CHA saving throw. On a failed save, the creature suffers as if affected by the "Bane" spell (-1d4 to attack rolls and -1d4 to all saving throws) for a single turn. A creature can not suffer this effect multiple times at the same time.

As a bonus action on your turn, you can move the spirit up to 30 feet to a space you can see.
