Hypnotic Pattern

Actions

Hypnotic Pattern (1/day). The adult green dragon magically creates the effect of the Hypnotic Pattern spell, using a DC of 12.


Mirror Image

Bonus Actions

Mirror Images (1/day). The adult green dragon magically creates three illusory duplicates of itself as in the Mirror Image spell. The duplicates have AC 11.


Projection

Reactions

Projection (1/day). When the adult green dragon is the sole target of an attack or spell, the adult green dragon may use their reaction to turn invisible and teleport up to 30 ft to an unoccupied location they can see. The invisibility lasts for up to 1 minute or until the adult green dragon makes an attack or casts a spell. Simultaneously, an illusionary version of the adult green dragon appears in the previous location and appears to be subjected to the attack or spell. The illusion ends when the invisibility ends and also fails to stand up to physical interaction. A character may also use an action to perform a DC 14 Investigation check to identify the illusion.


Phantom Mirage

Reactions

Phantom Mirage (1/day). When the adult green dragon becomes Bloodied, it creates 4 illusory duplicates of itself in unoccupied spaces within 30 feet. The duplicates vanish at the end of the adult green dragon's next turn or when struck by an attack. When a creature makes an attack against the adult green dragon that creature must roll a d6 for each duplicate. On a roll of 1, the attack hits a duplicate instead.


Reverse Fortune

Reactions

Reverse Fortune (Recharge 4-6). When the adult green dragon is hit by an attack, the adult green dragon magically reverses the fortune of the attack and forces it to miss. Until the end of its next turn, the adult green dragon gains advantage on the next attack it makes against the attacker.


Spectral Duplicate

Bonus Actions

Spectral Duplicate (1/day). The adult green dragon creates a spectral duplicate of itself in an unoccupied space it can see within 60 feet. While the duplicate exists, the adult green dragon is Invisible and Unconscious. The duplicate has the same statistics and knowledge as the adult green dragon and acts immediately in initiative after the adult green dragon. The duplicate disappears when the adult green dragon drops to 0 hp.
