Is this homebrew racial feat, Stonehide, balanced?
This feat uses the Dragonborn racial feat Dragonhide and the UA Stone Sorcerer Stone's Durability feature as a basis.
Prerequisite: Dwarf or Gnome
The mystical link between your soul and the magic of elemental earth grants you extraordinary resilience. You gain the following benefits:
- Increase your Strength, Constitution, or Wisdom score by 1, to a maximum of 20.
- As an action, you can gain a base AC of 13 + your Constitution modifier if you aren't wearing armor, and your skin assumes a stony appearance. This effect lasts until you end it as a bonus action, you are incapacitated, or you don armor other than a shield.
- Your unarmed strike uses a d4 for damage as long as your Stonehide is active.
