Fizban's Platinum Shield active

You create a field of silvery light that surrounds you. This field sheds dim light out to 5 feet. While surrounded by the field, you gain the following benefits:

Cover. You have half cover

Damage Resistance. You have resistance to acid, cold, fire, lightning, and poison damage.

Evasion. If you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead takes no damage if you succeed on the saving throw, and only half damage if it fails.
