Built Like an Ox

You beat obstacles with your muscles and when those fail you, you beat them by running through them.  Sometimes…. it’s a bit of both.  Gain the following benefits:

• Constitution saving throws can be made using your Strength modifier, and Strength saving throws can be made using your Constitution modifier.
• If you add your proficiency bonus to both Constitution and Strength saving throws, add 1 and 1/2 (rounded down) your proficiency bonus instead.
