Blightwind (Grim Hollow)

Blight. Any creature that touches the blightwind or hit it with a melee attack while within 5 feet of it must succeed on a DC 13 Constitution saving throw or become poisoned until the end of that creature's next turn.

Mist Form. The blightwind can enter a hostile creature's space, subjecting that creature to Blight, and stop there. A creature can also enter the blightwind's space. The blightwind can move through a space air can move through without squeezing. 

Multiattack. The blightwind makes two wind whip attacks. 

Wind Whip. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 14 (2d8+5) slashing damage, 4 (1d8) necrotic damage, and Blight.

Blight Vortex (Recharge 5-6). each creature within 20 feet of the blightwind must succeed on a DC 16 Strength saving throw or be pulled 20 feet straight toward the blightwind. If a creature would enter another creature's space, both creatures instead take 3 (1d6) bludgeoning damage and fall prone, for each 5 ft. moved before colliding. Creatures pulled into the blightwind's space take 142d8+5 necrotic damage and are subjected to Blight. A creature that fails the saving throw against Blight is blinded while poisoned due to that exposure to the trait.
