Keen Scent. Yeshir have advantage on Wisdom (Perception) and (Survival) tests based on scent.

Fear Aura. When they first hear or see a yeshir, halflings must make a DC 11 Wisdom saving throw or become frightened. Halflings do not gain advantage on this saving throw. If the target passes, they are immune to the fear aura effect for 1 hour.

Pack Tactics. The yeshir has advantage on an attack roll against a creature if at least one of the yeshir’s allies is within 5 feet of the creature and the ally isn't incapacitated.

Multiattack. A Mazchedeen makes two attacks: one with its bite and one with its claws.

ACTIONS

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: (1d6+2) piercing damage and the target must make a DC 12 Constitution saving throw, taking 2d6 poison damage and becoming poisoned on a failed save, or half damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way. Halflings are vulnerable to yeshir venom and make the saving throw to resist at disadvantage. Stout halflings make the saving throw without advantage and take regular damage on a failed save or half damage on a successful save.

Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: (1d4+2) slashing damage.

Challenge CR 4 (1,100 XP)

Incorporeal Movement. The dreamstealer can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Unnatural Aura. Wild and undomesticated animals can sense the unnatural presence of a dreamstealer at a distance of 30 feet and become frightened.

ACTIONS

Wisdom Drain. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: (3d8+4) necrotic damage. The target must succeed on a DC 16 Wisdom saving throw or its Wisdom score is reduced by 1d6 and it becomes confused (per the spell) until the end of its next turn. The dreamstealer heals 5 points of damage (10 on a critical) whenever it drains Wisdom, gaining any excess as temporary hit points.  

A confused creature can't take reactions and rolls a d10 to determine what it does during that turn. On a 1 to 4, the creature does nothing. On a 5 or 6, the creature takes no action but uses all its movement to move in a random direction. On a 7 or 8, the creature makes one melee attack against a random creature, or it does nothing if no creature is within reach. On a 9-10 the creature can act and move normally.

The Wisdom reduction lasts until the target finishes a long rest. As long as this reduction remains, the creature suffers from terrible nightmares when they sleep and must make a DC 16 Constitution saving throw or gain 1 level of exhaustion.

If the target’s Wisdom is reduced to 0 it is rendered insane. An insane creature can't take actions, can't understand what other creatures say, can't read, and speaks only in gibberish. Only a greater restoration spell can remove insanity and restore the character’s Wisdom restored to its starting value.

Wail of Doom (recharge 6). As an action, a dreamstealer can emit a bloodcurdling wail. All living creatures within a 100 foot radius that can hear the wail must make a DC 16 Wisdom saving throw or suffer 5d4 points of psychic damage and become frightened of the dreamstealer. A frightened creature can repeat the saving throw at the end of their next turn to shake off the frightened effect.
