Celestial Spirit

Ethereal Sight. The Celestial Spirit can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.

Incorporeal Movement. The Celestial Spirit can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Innate Spellcasting. The Celestial Spirit's spell casting ability is Wisdom (spell save DC 13). The Celestial Spirit can innately cast the following spells, requiring no material components:

At will: Guidance, Thaumaturgy, Detect Evil and Good

1/day: Spiritual Weapon, Dispel Evil and Good

Radiant Touch. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 17 (4d6 + 3) radiant damage.

Etherealness. The Celestial Spirit enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can't affect or be affected by anything on the other plane.

Radiant Visage. Each undead or evil aligned creature within 60 feet of the Celestial Spirit that can see it must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the frightened condition on itself on a success. If a target's saving throw is successful or the effect ends for it, the target is immune to this Celestial Spirit's Horrifying Visage for the next 24 hours.

Possession (Recharge 6). One humanoid that the Celestial Spirit can see within 5 feet of it must give permission to be possessed by the Celestial Spirit (the Celestial Spirit can roll an persuation or intimidation check against the creatures insight roll); the Celestial Spirit then disappears, and the target is incapacitated and loses control of its body. The Celestial Spirit now controls the body but doesn't deprive the target of awareness. The Celestial Spirit can't be targeted by any attack, spell, or other effect, and it retains its alignment, Intelligence, Wisdom, Charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target's statistics, but doesn't gain access to the target's knowledge, class features, or proficiencies.

The possession lasts until the body drops to 0 hit points, the Celestial Spirit ends it as a bonus action, the possesed creature removes permission or the Celestial Spirit is turned or forced out by an effect like the dispel evil and good spell. When the possession ends, the Celestial Spirit reappears in an unoccupied space within 5 feet of the body.

The Radiant Spirit can cast Spiritual Weapon, the weapon takes the form of a floating cross glowing white.
