Actions

Multiattack. The Lost makes two arm spike attacks.

Arm Spike. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:14 (2d10 + 3) piercing damage.

Embrace. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:25 (4d10 + 3) piercing damage, and the target is grappled (escape DC 14) if it is a Medium or smaller creature. Until the grapple ends, the target is frightened, and it takes 27 (6d8) psychic damage at the end of each of its turns. The Lost can embrace only one creature at a time.

Reactions

Tightening Embrace. If the Lost takes damage while it has a creature grappled, that creature takes 18 (4d8) psychic damage.

Lore

The Shadowfell's pervasive melancholy sometimes gives rise to strange incarnations of the plane's bleak nature. The sorrowsworn embody the forms of suffering that are inherent to the shadowy landscape, and they visit horror on those who stumble into their midst.
