Deathwolf

If the deathwolf fails a saving throw, it can choose to succeed instead.

When the deathwolf falls, it descends at a rate of 60 feet per round and takes no falling damage.

The deathwolf makes one Bite attack and two Claw attacks. It can replace one of these attacks with Phantom Deathwolf if available.

Melee Weapon Attack +10 to hit, reach 5 ft., one target. 14 (2d8 + 5) Piercing damage plus 9 (2d8) Necrotic damage. The target must succeed on a DC 16 Wisdom saving throw or have disadvantage on saving throws against the Frightened condition. This curse lasts until removed by the Remove Curse spell or other magic.

Melee Weapon Attack +10 to hit, reach 5 ft., one target. 12 (2d6 + 5) Slashing damage plus 4 (1d8) Necrotic damage.

The deathwolf creates a terrifying phantom of itself in the mind of a creature the deathwolf can see within 60 feet of itself. The target must succeed on a DC 17 Intelligence saving throw or have the Frightened condition for 1 minute.
While the target is Frightened, the phantom deals 21 (6d6) Psychic damage to the target at the start of each of the target's turns. A Frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

When a creature within 5 feet of the deathwolf makes an attack roll against it, the deathwolf forces the creature to succeed on a DC 17 Wisdom saving throw or have disadvantage on that roll. After the attack hits or misses, the deathwolf makes one Claw attack against the creature.

Immediately after taking damage, the deathwolf teleports up to 30 feet to an unoccupied space it can see that is in dim light or darkness.
