Additionally, small floating gemstones matching your gemstone infusion to explode out of your skin as a reaction to being attacked. When you aren’t wearing armor, your AC equals 15 + your Dexterity modifier.

Bejewelled Affirmation

Starting at 6th level, when you cast a spell that deals damage of the type associated with your gemstone infusion, you can add your Charisma modifier to one damage roll of that spell. At the same time, you can spend 1 sorcery point to gain resistance to that damage type for 1 hour.

Crystalline Wings

At 14th level, you gain the ability to sprout a pair of crystal wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.

You can’t manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.

Ornamental Aura

Beginning at 18th level, you can channel the innate beauty of your gemstone infusion- your skin briefly changing to said gemstone in an eruption of crystals - causing those around you to become awestruck. As an action, you can spend 5 sorcery points to draw on this power and exude an aura of awe to a distance of 80 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each creature that starts its turn in this aura must succeed on a Wisdom saving throw or be charmed  until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
