Thick Skin

You have been through hardship that would fell a lesser being. This hardship allows you to partially shield yourself from damage. When you take this feat:

• Increase your Constitution score by 1, to a maximum of 20.
• When you take damage, you can use a reaction to roll and use your Hit Dice. Add your Constitution modifier to the number rolled and reduce the damage by that total. The amount of Hit Dice you can roll during your reaction is equal to your proficiency bonus.
