Flesh of Dust and Stone (DEX)

Source: Complete Waifu Handbook

Prerequisite: Sala'dhin
Your flesh has become even more rough, coarse, and resilient.
You gain the following benefits:

• Increase your Constitution score by 1, up to a maximum of 20.
• You have resistance to fire damage.
• Your scales harden. While you aren’t wearing armor, you can calculate your AC as 13 + your Dexterity or Constitution modifier (your choice). You can use a shield and still gain this benefit.
