Gates of Heaven

8th-level conjuration

Casting Time:1 action

Range:90 feet

Components:V, S

Duration:Concentration, up to 1 minute

Choose a point within range. A 20-foot-high and 20-foot-wide marble arch appears, centered on it. The arch is a one-way gate from heaven and sheds bright light in a 90-foot cone emerging from the designated point. The aberrations, fiends, and the undead within the light must make a Wisdom saving throw. On a failed save, a creature takes 6d8 radiant damage and is frightened for 1 minute. On a successful save, the damage is halved and the creature is not frightened. Also, a celestial of your choice of challenge rating 2 or lower comes forth through the gate. The celestial disappears when it drops to 0 hit points or when the spell ends. The celestial is friendly to you and your companions for the duration. Roll initiative for the celestial, which has its own turns. It obeys no verbal commands you issue to it, but acts in the way that is most beneficial to you. The GM has the celestial’s statistics.

On each of your turns until the spell ends, you can use your action to make the gate shed bright light, dealing the radiant damage again, and summoning another celestial of challenge rating 2 or lower.
