Band of Focus

This ring grants the wearer the ability to split their concentration. While wearing this ring once per long rest you can have two concentration spells up at the same time. While this effect is active you have Disadvantage on CON Saving Throws to maintain concentration on both spells. When you take damage roll a d6 with odd and even denoting which of the two spells is at risk of failing.
