Carlyle's Surge Crown

When you cast this spell, you create a band of illuminated metal around your head, resembling a finely wrought circlet crown. While you are concentrating on the spell, this circlet cannot be removed by any means. 

While wearing the crown, you gain +1 to your Constitution saving throws. Additionally, your wild magic becomes easier to control; Whenever you roll on the wild magic table, you may roll a second d100 and use whichever result you choose.

At higher levels: When you cast this spell at a level higher than 5th level, you may extend the duration by 1 hour per spell level used above 5th level.
