Cosmic Transendance

The white of your eyes becomes permanently black and you gain the ability to perceive Eldritch beings.

As a bonus action you can transform into a Form of Madness once per long rest for up to 1 minute.
Your glimpses into the eldritch plane beyond have not gone unnoticed and your body takes on aspect of these ineffable forms.

• You gain temporary hit points equal to 1d10 + wisdom modifier
• Once during each of your turns, when you hit a creature with an attack, you can force it to make a Wisdom saving throw, (if you do not have a spellcasting modifier you use your charisma modifier) and if the saving throw fails, the target is frightened of you until the end of your next turn, if the creature fails the saving throw by more than 10 they gain a Short-Term Madness effect as described in the DMG p. 259.
• You are immune to the frightened condition and the effects of Madness.
• You gain Immutable Form, you are immune to any spell or effect that would alter your form.
