By gathering threads of shadow material from the Void, you create a Huge shadowy dragon 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 the illusion appears, any of your enemies that it can see must succeed on a Wisdom saving throw or become

Frightened
of it for 1 minute. If a Frightened creature ends its turn in a location where it doesn't have line of sight of 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 20m. At any point during its movement, you can cause it to exhale a blast of energy in a 20m cone originating from its space. When you create the dragon, choose a damage type: ACID, DARK, FIRE, HOLY, ICE, LIGHTNING, POISON, WATER, or WIND. Each creature in the cone must make a

Basic
Intelligence saving throw, taking 7d6 damage of the chosen damage type.

The illusion is tangible because of the shadow material 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 dragon 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 breath.
