Court the Flame

You court the power of a nearby fire to shield you against attacks and spells. Choose one torch-sized or larger fire within 5 feet of you when you cast this spell. For the duration of the spell, whenever you end your turn within 5 feet of that fire, you receive a +1d4 bonus to your AC and resistance to fire damage until the end of your next turn.

While this spell is active, if you would take a single instance of fire damage from an effect or ability, you can expend your reaction to reduce that damage to zero. If you do so, the spell ends.
