Hydaelyn

By gathering threads of shadow material from the Shadowfell, 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, enemies that can see it must succeed on a Wisdom saving throw or become frightened of it for 1 minute. 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 exhale a blast of energy in a 60-foot cone originating from its space. When you create the dragon, choose a damage type: acid, cold, fire, lightning, necrotic, or poison. Each creature in the cone must make an Intelligence saving throw, taking 7d6 damage of the chosen damage type on a failed save, or half as much on a successful save.
