Ether Bees

 You summon a swarm of ethereal, ghost-like bees.

The bees swarm a target of your choosing, dealing 1d6 piercing damage at the start of the target's turn.

The target can make a Dexterity saving throw at the beginning of their turn, taking half damage from the bees on a success.

If the target takes damage from the bees for the full spell duration, the target is poisoned and speed is decreased by 5ft. The bees will follow a target wherever they go for the duration of the spell. They will not follow a target into another plane, beyond 1,000 feet, or into water deep enough to submerge the target.
