Components: SM (A golden cross for an angel and a bloodstone for a demon)
Duration: Concentration, up to 1 minute
By gathering threads of shadow material from the Shadowfell, you create an illusory mimic or an angel or demon in an unoccupied space that you can see within range. The illusion lasts for the spell’s duration and occupies its space as if it were a creature. When you create the illusion you determine the type of angel or demon and its weapons and armor.
Angel. When the illusion appears, any of your enemies that can see it must succeed on a Wisdom saving throw or become Blinded by it for 1 minute. If a charmed creature ends its turn in a location where it doesn’t have line of sight to the illusion, it can repeat the saving throw, ending the effect on itself on a success. As a bonus action on your turn, you can move the illusion up to 60 feet. At any point during its movement, you can cause it to exude an aura of light in a 30-foot radius sphere originating from its space. Each creature in the sphere must make an Intelligence saving throw a creature takes 6d8 radiant damage on a failed save, or half as much damage on a successful one.
Demon. When the illusion appears, any of your enemies that can see it must succeed on a Wisdom saving throw or becomes stunned by it for 1 minute. If a charmed creature ends its turn in a location where it doesn’t have line of sight to the illusion, it can repeat the saving throw, ending the effect on itself on a success. As a bonus action on your turn, you can move the illusion up to 60 feet. At any point during its movement, you can cause it to exude an aura of death in a 30-foot radius sphere originating from its space. Each creature in the sphere must make an Intelligence saving throw a creature takes 6d8 necrotic damage on a failed save, or half as much damage on a successful one.
The illusion is tangible due to the shadow strands used to create it, but attacks miss it automatically. it succeeds on all saving throws, and it is immune to all damage and conditions. A creature that uses an action to examine the creature can determine that it is an illusion by succeeding on an Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the creature can see through it and has advantage on saving throws against its aura. Once a creature succeeds the saving throw of this spell, they automatically save each other saving throw caused by the spell for the duration.
