Dirt Mournling

When the mournling dies, the sadness they contain is released into the world. Each creature within 30 feet of the mournling who can hear them must make a DC 19 Wisdom saving throw, taking 22 (4d10) psychic damage on a failed save, or half as much damage on a successful one.

The mournling is immune to any power, spell, or effect that would alter their form.

When the mournling leaves a space, the ground in that space becomes difficult terrain for their enemies for 10 minutes.

The mournling makes three attacks using Slam, Mudslide, or both, and they can use Dust Storm, if available.

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 28 (4d10 + 6) bludgeoning damage, and the target is grappled (escape DC 20). While grappled in this way, the target is restrained.

Ranged Weapon Attack: +12 to hit, range 30/60 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage. If the target is a Huge or smaller creature, the target and each Huge or smaller creature of the mournling's choice within 5 feet of the target are pulled up to 30 feet toward the mournling.

The mournling hurls dirt, gravel, and sand. Each creature within 60 feet of them must succeed on a DC 19 Constitution saving throw or be blinded for 1 minute (save ends at end of turn).

The mournling teleports to an unoccupied space they can see within 30 feet of them.

When the mournling is hit by a melee weapon attack, they capture the weapon that struck them in quickhardening mud, disarming the attacker. A creature who can reach the weapon can use an action or bonus action to make a DC 19 Strength (Athletics) check, freeing the weapon on a success. The mournling can't use this reaction on attacks made with natural weapons.
