3rd Level Divine Evocation (named)
Casting Time: 1 action
Range: 12 sqr. (18m)
Components: V, S, M (a shard of celestial crystal)
Duration: 1 hour, concentration
You summon a radiant pillar of divine light at a point within range. The pillar reveals fiends within 12 sqr. (18m), even through walls and magical darkness. Fiends in the area also lose invisibility and cannot benefit from concealment.
While the pillar persists, any creature in the radius has advantage on attack rolls against fiends. Fiends that start their turn in the area take 2d6 radiant damage.
