Gibbering (recharge 5-6). As an action, you can awaken the mouths in your body until the start of your next turn, causing them to murmur and chatter. This cacophonous gibbering overcomes the senses of any creature that hears it within 20 feet of you. Creatures within range must succeed on a Wisdom saving throw, the DC for this saving throw equals 8 + your Constitution modifier + twice your proficiency bonus. On a failure, the creature can't take reactions until the start of its next turn and rolls a d8 to determine what it does on its turn. On a 1 - 4, the creature does nothing. On a 5 - 6, the creature takes no action or bonis action and uses all its movement to run as far as it can in a randomly ditermined direction. On a 7 - 8, the creature makes a melee attack against a randomly ditermined creature within its reach or does nothing if it can't make such an attack.

Mouther's Nature. You are a carnivore and require the same amount of food a normal Medium-sized creature needs each day. While this food sates you for the day it simply isn't enough, as the hunger from your abberative origins demands more. If you do not sate this hunger using your Devour trait you must make a Intelligence saving throw at the beginning of your next long rest to maintain your form and calm the mouths throughout your body that demand to be fed. On a failed save, you indiscriminately attack or hunt for the nearest living creature and upon their death Devour them. The DC for this saving throw is 10 and increases by 2 for long rest you do not sate it. This hunger can only be sated by consuming a living creature. While sated you don't need to eat or drink as a normal Medium-sized creature would each day. You can go a number of days equal to 1 + your Constitution modifier without sating this hunger.

Devour. As an action, you can consume an incapacitated creature within 5 feet of you, sating your hunger. You can only safely devour creatures that are or smaller in this way. Medium sized creatures sate you for 10 days, Small sized creatures for 5 days and Tiny sized creatures sate you for a day. You gain no benefit from devouring constructs. If you devour a Large-sized creature, you have overeaten, causing your physical form to visibly melt, your body and maws becoming lethargic and sluggish. During this time, your walking speed becomes 10 feet and you are affected by the poisoned condition until you have digested your meal. Digesting this meal takes 24 hours to do so and satisfies you for a month. You cannot eat a creature that has a size of Huge or larger without breaking it into smaller parts. Alternatively, when you reduce a living creature within 5 feet of you to 0 hit points, you can, as a reaction, devour them completely gaining temporary hit points equal to your level + your Constitution modifier. While this provides you with a wealth of nourishment instantly, it causes your hunger to return faster by only sating you for half as a long, rounded down. You regain use of this trait once you complete a long rest. After eating a creature their memories will be consumed. Any consumed creature's consciousness will be fully intact and but will be completely unable to do anything. The consumed creature cannot be resurrected as their brain is still kept alive.

Languages. You speak, read, write and understand Common and Undercommon. While you are capable of speech and writing you don't do so with the accuracy of most other humanoids, you sometimes use words incorrectly or write nonsense.
