Busy Bee

You summon a spirit that animates the bee carving for the duration, which attaches to your clothing, sits on your equipment, or otherwise remains within 1 foot of you. If the bee is ever more than 1 foot away from you, the spell ends.

When you lose concentration on a spell of 3rd level or lower, the spirit animating the bee takes over and maintains concentration on that spell until that spell ends or this spell ends, whichever has a shorter duration. While the spirit is maintaining concentration on a spell, you can't cast a spell that requires concentration.

The spirit can't be attacked or destroyed, and its concentration can't be interrupted. You can dismiss this spell at any time (no action required), and a dispel magic spell cast on the bee, if successful, ends this spell as well. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the spirit can concentrate on spells with a spell level up to the spell slot you used, and the duration increases by 1 hour for each slot level above 3rd.
