Focus Circlet
While wearing this silver circlet, you gain a bonus to Constitution saving throws that you make to maintain your concentration on a spell you cast equal to the spell's level, up to a maximum of +3.
"Still the chaos in your mind. Focus! While your flesh may be under assault, only you have control of your racing thoughts. Tame them! Harness and steer your concentration toward your goals. Do not be trifled with the aches and bruises of your body, for they are secondary to what lies inside you."
