Divine Fury

You call upon the divines to imbue you with holy rage. Until the spell ends, you can't cast spells or concentrate upon spells, you gain +1 to your AC, and your weapon attacks deal an additional 1d8 radiant damage. After the spell ends, you must succeed a DC 13 Constitution saving throw or suffer 1 level of exhaustion.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you gain an additional +1 to your AC and the damage increases by 1d8 for every two slot levels above 2nd.
