Smoke Construct (5e Creature)
From D&D Wiki
Medium elemental, unaligned
Damage Resistances lightning, thunder; bludgeoning, piercing, and slashing from nonmagical attacks
Air Form. The construct can enter a hostile creature's space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.
Bound. The smoke construct is magically bound to a large bowl, which it was made in. As long as the construct and its bowl are on the same plane of existence, the bowl's owner can telepathically call the construct to travel to it, and the construct knows the distance and direction to the bowl. If the construct is within 60 feet of the bowl's owner, half of any damage the owner takes (rounded up) is transferred to the construct.
Sneak Attack (1/Turn). The construct deals an extra 14 (4d6) damage when it hits a target with a slam attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the construct that isn't incapacitated and the construct doesn't have disadvantage on the attack roll.
Multiattack. The construct makes two slam attacks.
Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage.
Armor Removal (Recharge 4-6). The construct makes a slam attack. On a hit, the target must succeed on a DC 15 Dexterity saving throw or the construct pushes a piece of armor off the target, causing it to fall straight to the ground.
Smoke constructs are the result of magical experimentation. Summoners began to notice that traces of air and fire elementals can be combined, though never naturally. The best method of construction was to simply combine the necessary ingredients in a large bowl. This bowl is then used as a phylactery. Should it be destroyed, the construct fades and dies immediately.
