Actions

Multiattack. The death kiss makes three tentacle attacks. Up to three of these attacks can be replaced by Blood Drain, one replacement per tentacle grappling a creature   Tentacle. Melee Weapon Attack: +8 to hit, reach 20 ft., one target. Hit: 14 (3d6 + 4) 3d6+4 piercing damage, and the target is grappled (escape DC 14) if it is a Huge or smaller creature. Until this grapple ends, the target is restrained, and the death kiss can't use the same tentacle on another target. The death kiss has ten tentacles.   Blood Drain. One creature grappled by a tentacle of the death kiss must make a DC 16 Constitution saving throw. On a failed save, the target takes 22 (4d10) 4d10 lightning damage, and the death kiss regains half as many hit points.
