Weeping Angel

False Appearance. The weeping angel is indistinguishable from a stone statue. 

Quantum Locked. The weeping angels would "become" unmovable statues as soon as any sentient life-form looked upon them, only to be freed to their true form when that individual looked away. 

Don't Blink. On the start of each turn every creature attempting to focus its sight on the weeping angel must make a CON save (DC 13 initially) to avoid blinking. This increases by 1 every turn and resets once the creature has failed.

Pack Tactics. The Angel has advantage on attack rolls against a creature if at least one of its allies is within 5 feet of the creature and the ally isn't incapacitated.

Language. The Weeping Angels did not naturally possess intelligible voices although they could produce screeches as a form of laughter, and the infant weeping angels could produce childlike giggles. 

Communication. The weeping angels also possesses the ability to communicate with each other over long distances, even when frozen.

Corpse Speak. The weeping angel can steal the voice of a dead person, It will also get the memories of the person.

Multiattack. The Weeping Angel makes two attacks.

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit:  (2d6 + 3) piercing damage. 

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., 1 target. Hit:  (2d8 + 4) piercing damage.

Snuff Light. Can remove any light source (up to 3 per bonus action). 

Touch. (Activated when in contact with another non-weeping angel creature) The target must succeed on a Charisma saving throw (DC 15) or else be immediately thrown in a pocket dimension populated only by the creatures the weeping angel has consumed. The target suffers no damage, conditions, or other effects from this attack, but may be rather confused. At the start of the captured creature's turn, the creature can try to make the Charisma saving throw again as an action to free itself, at a success the creature returns to its position the moment the weeping angel touched it, at a fail the creature remains in the pocket dimension. 

The weeping angel can take a legendary action, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The weeping angel can take up to 3 legendary actions per round.

Each time a character suffers an aging touch they also gain a level of exhaustion. Years Aged=Y=X*Species Average Death Age, X=Damage Dealt By Aging Touch/Maximum Hit Points.
