Avatar of Fear

Avatar. If the avatar is subjected to an effect that would cause it to be frightened, it redirects it at the creature causing it, requiring them to make the saving throw against it, and making that creature frightened of the avatar for the duration. 

Eat Their Fear. If the avatar attacks a frightened creature, it regains hit points for half of the damage it deals. 

Unorthodox Attacks. The avatar uses its strangely shaped limbs to twist and swing from odd angles. This gives it a natural +1 to its attacks (included in the attack).

Aggressive Jumper. The avatar can jump up to 100 ft. towards a creature that is hostile to it, but only if that creature is not facing directly at it. Unless the avatar chooses otherwise, this movement is entirely silent. 

Multiattack. The avatar makes two attacks, one with its bite and one with its scythe. It can also use Siphon Fear if it is available. It can also use Distorted Mimicry as a bonus action. 

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (1d10 + 4) piercing damage and the target must make a DC 12 Wisdom Save or it is frightened for one minute. 

Scythe. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 10 (2d6 + 4) slashing damage and 3 (1d6) psychic damage. 

Siphon Fear (Recharge 5-6). The avatar mentally drains the life of those terrified of it. Any creature within 60 ft. of the avatar that is frightened by it must make a DC 12 Wisdom save, taking 12 (3d8) psychic damage on a failure, or half as much on a success. The avatar then regains hit points equal to the full amount of damage dealt. 

Distorted Mimicry. The avatar repeats the last few words or sentences of a prior victim, or unleashed a scream in a much more warped manner of a victim. One creature that can hear the avatar of its choice must make a DC 12 Charisma save or it has disadvantage on its next attack roll, saving throw, or ability check while it is still within 1 mile of the avatar.
