Soul Monger

The soul monger has advantage on saving throws against being Charmed, and magic can't put it to sleep.

The soul monger has advantage on saving throws against spells and other magical effects.

When the soul monger reduces a creature to 0 hit points, the soul monger can gain temporary hit points equal to half the creature's hit point maximum. While the soul monger has temporary hit points from this ability, it has advantage on attack rolls.

Any beast or humanoid, other than a shadar-kai, that starts its turn within 5 feet of the soul monger has its speed reduced by 20 feet until the start of that creature's next turn.

The soul monger makes two phantasmal dagger attacks.

Melee Weapon Attack +7 to hit, reach 5 ft., one target. 13 (4d4 + 3) Piercing damage plus 19 (3d12) Necrotic damage, and the target has disadvantage on saving throws until the start of the soul monger's next turn.
