From D&D Wiki
|Self (10-foot radius)
|Concentration, up to 1 minute
- You conjure a dome of light that surrounds you in a protective radiant barrier.
You summon an orb of light that expands to a 10-foot radius around you and remains for the duration. You and each creature you choose gains a +2 bonus to AC against spell attacks and to saving throws against spells while inside the dome. Each creature you choose that enters or starts their turn in the dome must make a Constitution saving throw equal to the casters spell DC. The creatures take 4d8 radiant damage on a failed save and half that on a successful one.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radiant damage increases by 1d8 for every spell slot above 3rd.
