Thickheaded

Prerequisite: Intelligence and Wisdom ability scores of 12 or lower

You've taken more than a few hits to the head. You struggle to understand some things, but you manage to turn this to your advantage. You gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• If you are required to make a Wisdom or Intelligence saving throw, you may use your reaction to automatically succeed on the saving throw. You must decide to use this ability before making the saving throw. Once you use this ability, you can't do so again until you finish a long rest.
