: Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) bludgeoning damage, and the darkmantle attaches to the target. If the target is Medium or smaller and the darkmantle has advantage on the Attack

and unable to breathe while the darkmantle is attached in this way.
While attached to the target, the darkmantle can Attack
no other creature except the target but has advantage on its Attack
rolls. The darkmantle's speed also becomes 0, it can't benefit from any bonus to its speed, and it moves with the target.
A creature can detach the darkmantle by making a successful DC 13 Strength
check as an Action

: A 15-foot radius of magical Darkness
extends out from the darkmantle, moves with it, and spreads around corners. The Darkness
lasts as long as the darkmantle maintains Concentration
, up to 10 minutes (as if concentrating on a spell). Darkvision
can't penetrate this Darkness
, and no natural light can illuminate it. If any of the Darkness
overlaps with an area of light created by a spell of 2nd Level
or lower, the spell creating the light is dispelled.
