Bianca the White Wolf

Shapechanger. Bianca can use her action to polymorph into a wolf-humanoid hybrid or into a wolf, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

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

Multiattack. (Humanoid or Hybrid Form Only). Bianca makes three attacks: one with its bite and two with its claws (hybrid form).

Bite (Wolf or Hybrid Form Only). Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 32 (6d8 + 5) piercing damage. If the target is a humanoid, it must succeed on a DC 14 Constitution saving throw or be cursed with werewolf lycanthropy.

Claws. (Hybrid Form Only). Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 15 (4d4 + 5) slashing damage.

While charmed by Bianca, a target is incapacitated. If the charmed target is more than 5 feet away from Bianca, the target must move on its turn towards her by taking the most direct route, trying to get within 5 feet. It doesn't avoid opportunity attacks, but before moving into damaging terrain, such as lava or a pit, and whenever it takes damage from a source other than Bianca, the target can make a DC 20 Wisdom saving throw. A charmed target can at the end of each of its turns can make a DC 20 Wisdom saving throw. If the saving throw is successful, the effect ends on it.
