A divine guardian appears for the duration in an unoccupied space of your choice that you can see within range. The guardian is Large, and occupies its space. You can choose the appearance of the guardian.

Any enemy that moves to a space within 10 feet of the guardian for the first time on a turn or starts its turn there makes a Dexterity saving throw. The creature takes 20 radiant or necrotic damage on a failed save (your choice), or half as much damage on a successful one. The guardian vanishes when it has dealt a total of 60 damage.
