Thick Rind

The shell that nurtured you as a young sprout has grown tough and unyielding. It resembles hardened wood or polished stone, offering natural protection against blows and buffeting forces.  You gain the following benefits:

• Increase your Constitution score by 2, to a maximum of 20.
• Your skin hardens. While you aren’t wearing armor, you can calculate your AC as 14 + your proficiency bonus. You can use a shield and still gain this benefit.
