Shapechanger. Zendrik can use its 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. Zendrik has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Legendary Resistance (2/Day). When the Zendrik fails a saving throw, he can choose to succeed instead.

Monk Training. Zendrik retained some of his monk abilities even after his change. He has 12 ki points available and regains them at dusk. He can use ki points when he hits with a melee weapon attack to inflict one of the following additional effects:

• Aggrevated Push (Costs 1 Ki point). The target creature must succeed on a DC 16 Strength saving throw or be pushed 15 feet away from Zendrik.
• Gutting Strike (Costs 1 Ki point). The target creature must succeed on a DC 16 Constitution saving throw or begin to bleed furiously. A bleeding creature takes 3 (1d6) necrotic damage at the start of its turns until it or another creature within 5 feet of them makes a successful DC 12 Wisdom (Medicine) check to stop the bleeding. Any magical healing instantly stops the bleeding.
• Disorientating Strike (Costs 1 Ki point). The target creature must succeed on a DC 16 Dexterity saving throw or fall prone. While prone in this way the creature is unable to take reactions.

Regeneration. Zendrik regains 10 hit points at the start of each of its turns. If the Zendrik takes damage from a silver weapon, this trait doesn't function at the start of the Zendrik's next turn. Zendrik dies only if it starts its turn with 0 hit points and doesn't regenerate.

Multiattack. Zendrik makes two attacks: two with his Spear (humanoid form) or one with its Bite and one with its Claws (dire wolf or hybrid form).

Bite (Dire Wolf or Hybrid Form Only). Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) piercing damage plus 10 (3d6) necrotic damage. If the target is a Humanoid, it must succeed on a DC 14 Constitution saving throw or be cursed with lycanthropy.

Claws (Dire Wolf or Hybrid Form Only). Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Spear (Humanoid Form Only). Melee or Ranged Weapon Attack: +11 to hit, reach 5 ft. or range 20/60ft, one target. Hit: 13 (2d6 + 6) piercing damage, or 15 (2d8 + 6) piercing damage if used with two hands.

Call the Mists (Costs 6 Ki Points; Recharges on a Short or Long Rest). Zendrik calls the Mists of Barovia to aid him in his hunt, which causes mist to gather around him in a 300-foot radius for 10 minutes. The mist is considered heavily obscured for creatures other than Zendrik and his wolves. The use of a spell like gust of wind or wind wall disperses this fog for 1 minute.

Mist Form (Costs 2 Ki Points). When Zendrik is hit with an attack, he can use his reaction to disperse his form into mist for a brief moment. He gains resistance to the damage dealt for that attack only.

Zendrik can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. Zendrik regains spent legendary actions at the start of its turn.

Strike. Zendrik makes one Claws attack (dire wolf or hybrid form only) or one Spear attack (humanoid form only).

Form Mistborn Wolf (Costs 2 Actions and 2 Ki points). Zendrik channels his ki into forming the mist around him into a Mistborn Wolf. The wolf takes their turn immediately and is destroyed when it or Zendrik is reduced to 0 hit points

Bite (Costs 3 Actions). Zendrik changes into hybrid or dire wolf form and then makes one Bite attack.
