Hideous Appearance

Your appearance has grotesquely transformed. You may be a hulking mass of flesh, adorned with countless eyes, or a bone-and-tusk-covered natural weapon. Regardless of your true form, you’re horrific to behold. You can suspend this form and manifest the appearance of the humanoid you once were, but this is taxing and requires concentration. This form is not
permanent, and moments of stress are likely to reveal your true nature. Your true form is revealed in the following situations:
• Concentrating on a spell.
• Gaining the unconscious condition.
• Entering hallowed ground.
• Choosing to reveal yourself.
In events of extreme emotional or physical stress, a GM may call for a Constitution saving throw with a DC of their choosing to see if you maintain your humanoid form. Non-evil creatures that witness your true form become instantly hostile to you, unless the GM decides otherwise.
