Master of Illusions

Your knowledge of illusory spells, as well as the Astral Plane and it’s many unique oddities, has allowed you to access extraordinary powers of illusion. You gain the following benefits:

• You know that an illusion or illusory effect is indeed an illusion or illusory effect if it is within 60 feet of you. In other words, you cannot be fooled by any illusion or illusory effect that is within 60 feet of you.
• You have the special ability to damage other creatures with a mist that appears to be an illusion, seemingly trapping creatures in another plane of existence. As an action, purple mist extends outward from you and covers the ground in a 30 foot radius around you. The mist remains existent for up to 3 rounds of combat or until you make it disappear using a bonus action, and creatures that end their turn within the mist (excluding yourself) must make a Wisdom saving throw (DC equals 10 plus your level, maximum of 20) to avoid taking psychic damage equal to your level plus your choice of either your Intelligence, Wisdom, or Charisma ability modifier. After you use this ability, you cannot do so again until a week has passed.
• Immediately after you use the ability above, and if there are creatures other than yourself within the radius of the mist when you use the ability, you can use a bonus action to shape the mist into terrifying, illusive images, forcing creatures within the mist to make a Wisdom saving throw to avoid being frightened by you for the next 3 rounds of combat. Creatures with the blinded condition are immune to this effect. You can use this ability only immediately after you use the mist ability above, assuming you can use a bonus action on that turn, and you can’t use it again in any other way until the next time you use the mist ability.
