Vamipre Bridesmaid

Undead Fortitude: If damage reduces the bridesmaid to 0 hit points, it must make a DC5+damage Constitution saving throw, unless the damage is radiant or from a critical hit.  On a success, the bridesmaid drops to 1 hit point instead.

Sunlight Sensitivity: While in sunlight, the bridesmaid has disadvantage on attack rolls, as well as Wisdom checks that rely on sight.

The bridesmaid makes two attacks: one with its claws and one with its bite.

Claws: Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 3) slashing damage.

Bite: Melee Weapon Attack: +5 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the bridesmaid, incapacitated, or restrained. Hit: 6 (1d4 + 3) piercing damage plus 7 (2d6) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and the bridesmaid 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.

Retaliation: When a creature within 5 feet of the bridesmaid hits it with a melee attack, the bridesmaid can make a melee attack with its claws against that creature.
