Chaos Horror

Gibbering. The Chaos Horror's many forming mouths babble and scream incoherently when it sees any creature and isn't incapacitated. Each creature that starts its turn within 20 feet of the Chaos Horror, and can hear the gibbering, must succeed on a DC 10 Wisdom saving throw. On a failure, the creature is horrified deeply. Each round this saving throw must made by creatures that can hear the Chaos Horror, on a failure all the creatures attacks and ability saves are at disadvantage until the beginning of the next round. 

Multiattack. The Chaos Horror makes three bite attacks to anyone or up to three creatures within 10', as if a pseudo pod attack. 

Bite. Melee Weapon Attack: +2 to hit, reach 10 ft., one creature. Hit: 7 (2d6) piercing damage. If the target is Medium or smaller, it must succeed on a DC 10 Strength saving throw or be knocked prone. If the targeted creature is reduced to zero hit points by this damage, the Chaos Horror will begin to eat that creature and thus lose that one pseudo pod to attack others. Each round the unconscious creature rolls Death Saves at disadvantage. 

Eyes of Horror (3 times a day). The Chaos Horror forms many eyes, just as it does mouths. Each round, the Chaos Horror may have an eye fix onto one random creature. If that creature fails a Wisdom saving throw of DC10, that creature will flee in complete horror. This is only broken if the creature makes a saving throw in subsequent rounds or within three rounds.
