Blood Wolf

Frightful Gaze. A creature of the bloodwolf's choice that is within 120 feet of the bloodwolf and aware of it must succeed on a DC 19 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the bloodwolf's Frightful Gaze for the next 24 hours.

Keen Hearing and Smell. The bloodwolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Regeneration. The bloodwolf regains 20 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight or running water. If the bloodwolf takes radiant damage or damage from holy water, this trait doesn't function at the start of the bloodwolf's next turn.

Spider Climb. The bloodwolf can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Multiattack. The bloodwolf makes two attacks, only one of which can be a bite attack.

Vampiric Bite(2/Day). Melee Weapon Attack: +15 to hit, reach 5 ft., A creature that is grappled by the bloodwolf, incapacitated, or restrained. Hit: 19 (2d10 + 8) piercing damage plus 9 (2d8) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the bloodwolf 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.
