Fire Shield

From Player's Handbook, page 242.

Description
4th-level evocation


 * Casting Time: 1 action
 * Range: Self
 * Components: V, S, M (a bit of phosphorus or a firefly)
 * Duration: 10 minutes

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.
