Vampiric Cloud

Antimagic Susceptibility. The vampiric cloud is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the vampiric cloud must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute.

Fog. The area within 20 feet of the vampiric cloud is heavily obscured.

Liquid Form. The vampiric cloud can enter an enemy’s space and stop there. It can also  move through a space as narrow as 1 inch wide without squeezing.

Living Spell. At the start of each of the vampiric cloud's turns, any creature in its space is targeted by the following spells if the vampiric cloud isn’t incapacitated (save DC 14, +6 to hit with spell attacks): cloudkill and vampiric touch.

Slam. Melee Spell Attack: +6 to hit, reach 5 ft., one creature. Hit: 7 (2d6) necrotic damage and 9 (2d8) poison damage, and the vampiric cloud regains hit points equal to half the amount of necrotic damage dealt.

Engulf. The vampiric cloud moves up to its speed. While doing so, it can enter Large or smaller creatures' spaces. Whenever the vampiric cloud enters a creature's space, the creature must make a DC 14 Dexterity saving throw.

On a successful save, the creature can choose to be pushed 5 feet back or to the side of the vampiric cloud. A creature that chooses not to be pushed suffers the consequences of a failed saving throw.

On a failed save, the vampiric cloud enters the creature's space, and the creature is engulfed. The engulfed creature can't breathe and is restrained. When the vampiric cloud moves, the engulfed creature moves with it.

An engulfed creature can try to escape by taking an action to make a DC 14 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the vampiric cloud.
