Primal Flame

You can use your bonus action to wreathe yourself in the power of the Elemental Plane of Fire. Your transformation lasts for 1 minute, until you end it as a bonus action, or when you fall unconscious. During it, you gain the following benefits:

• You gain resistance to fire damage. If you have resistance from another feature, you gain immunity to fire damage instead.
• Weapon attacks deal fire damage equal to your proficiency bonus.
• When you cast a spell that deals fire damage, you may roll an additional damage die to the damage roll.
