Thin and wispy flames wreathe your body for the Duration, shedding bright light in a 10-foot radius and dim light for an additional 10 feet. You can end the spell early by using an Action to dismiss it.

The flames provide you with a warm Shield or a chill Shield, as you choose. The warm Shield grants you Resistance to cold damage, and the chill Shield grants you Resistance to fire damage.

In addition, whenever a creature within 5 feet of you hits you with a melee Attack, the Shield erupts with flame. The attacker takes 2d8 fire damage from a warm Shield, or 2d8 cold damage from a cold Shield.
