Chiroptera

Standing Leap. The chiroptera's long jump is up to 30 feet and its high jump is up to 15 feet, with or without a running start. It takes no falling damage after making a high jump of 15 feet or less.

Sunlight Sensitivity. While in sunlight, the chiroptera has disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight.

Claw. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (2d8+7) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the chiroptera can't claw another target.

Bite. Melee Weapon Attack: +10 to hit, reach 5 ft.,one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained. Hit: 14 (2d6 + 7) piercing damage plus 10 (3d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the chiroptera regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. 

Deadly Leap. If the chiroptera jumps at least 15 feet as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC 16 Strength or Dexterity saving throw (target's choice) or be knocked prone and take 14 (2d6 + 7) bludgeoning damage plus 14 (2d6 + 7) slashing damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the chiroptera's space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in the chiroptera's space.

Fire Breath (Recharge 5–6). The chiroptera exhales fire in a 15-foot cone. Each creature in that area must make a DC 16 Dexterity saving throw, taking 45 (13d6) fire damage on a failed save, or half as much damage on a successful one.
