Smoke Form. The elemental can enter a hostile creature’s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.

ACTIONS                                  
Multiattack. The belker makes two claw attacks.

Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target.
Hit: 14 (2d8 + 5) bludgeoning damage.

Smoke Claws (Recharge 4-6). Each breathing creature in the elemental’s space must make a DC 15 Constitution saving throw or inhale part of the creature. Smoke inside the victim solidifies into a claw and attacks the target from within. On a failure, a target takes 17 (4d8 + 2) piercing damage. On a success the creature spends the turn coughing and choking. A successful save ends the secondary effect.
