Weeping Angel

Blink. At the start of the it's turn, the angel can force each creature that can see it to make a DC 13 Wisdom saving throw. On a failed save, a creature must blink or avert its eyes. If it does so, the creature can’t see the angel until the end of the angel's turn.

False Appearance. While the angel remains motionless, it is indistinguishable from an inanimate statue.

Immutable Form. The angel is immune to any spell or effect that would alter its form.

Quantum Lock. The angel is paralyzed while another creature can see it. While the angel is paralyzed in this manner, it gains resistance to all damage.

Multiattack. The angel makes two attacks with its claws.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage. Instead of dealing damage, the angel can grapple the target (escape DC 12).

Banishing Touch (Recharges 6). The angel touches a creature within 5 feet of it that is grappled, incapacitated, or restrained. If the creature is not an aberration, it must make a DC 13 Charisma saving throw. On a failed save, the creature is magically banished to a random location on its home plane in the distant past. Until the creature dies, the angel must concentrate on this effect (as if it were concentrating on a spell). It can only concentrate on one target at a time. If the angel loses its concentration before the target dies, the creature reappears in the space it left or in the nearest unoccupied space if that space is occupied, and gains the benefits of a long rest. Otherwise, the creature doesn’t return.
   At the end of each of the angel's turns, the banished creature ages 7 (1d6 + 4) years, and the angel regains hit points equal to that amount.
