Gift of The Firebrand (Tier One)

Passive: You become permanently fireproof against small and/or weak fires like candles, bonfires, fireplaces, and stoves (this includes your clothes and items), all non-magical fire damage you take is reduced by half, and you have advantage on saving throws against magical fire.

Active: When you are reduced to 0 hit points but not killed outright, all creatures within a 5 ft radius sphere centered on you must make a DC 10 + double your proficiency bonus DEX save. On a failure, creatures in this area take a number of d8 equal to your proficiency bonus of fire damage and half as much on a success.
