Unholy Resistance: This vampyre is resistant to all damage not dealt by a silvered weapon or by a spell not cast through a silvered spellcasting focus.

Ambush Predator: The vampyre can take 1 minute to conceal itself within the swamp. If it does so, it can take a 10 on the d20 roll for its stealth check, even if it rolls lower than this.

Sunlight Vulnerability: If in direct sunlight, the vampyre takes 10 radiant damage at the start of its turn and has disadvantage on ability checks and attacks.

Multiattack. The vampire makes three attacks, only one of which can be a bite attack.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 8 (2d4 + 3) slashing damage. Instead of dealing damage, the vampire can grapple the target (escape DC 13).

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained. Hit: 6 (1d6 + 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 vampire 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.
