Epic Boon: Primordial Crystal Deva

You have been infused with the heart and essence of primordial flames and jagged crystals. Your skin is now powerful stone and crystal, while your blood flows with primordial fire. You now gain the following benefits:

• You are immune to fire damage.
• You have an Unarmored Armor Class of 12 + your Dexterity modifier + your Constitution modifier. You lose this benefit if you are wearing any armor, though you can still use a shield and gain this benefit.
• Any fire damage you deal from any source ignores fire resistance and treats fire immunity as if it were fire resistance. 

You also gain certain spellcasting capabilities from your ascendant primordial form. You gain the following spells that use your Wisdom modifier as your spellcasting modifier. All spells are cast at their lowest level and spell slots cannot be used to cast them.

• Fire Bolt (at will)
• Scorching Ray (3/long rest)
• Fireball (2/long rest)
• Fire Storm (1/long rest)
