Crystalk (5e Creature)
From D&D Wiki
Medium plant, lawful neutral
Skills Nature +3
Onion Blood. A creature that moves within 5 feet of the crystalk or hits it with a melee attack while within 10 feet of it must successfully make a DC 12 Constitution saving throw or become blinded until the start of its next turn.
Spider Climb. The crystalk can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Vegetal Regrowth. The crystalk regains 1 hit point per minute if it has at least 1 hit point. Attacks which deal 5 or more slashing damage cut a chunk with 1 hit point off the crystalk; if given time to regain all its hit points, this chunk becomes a copy of the original crystalk.
Multiattack. The crystalk uses its Bloody Tears and its Scream.
Bloody Tears. The crystalk forcibly ejects blood from its eye. Each creature within 5 feet of a point the crystalk chooses that is within 20 feet of it makes a DC 12 Constitution saving throw, taking 3 (1d6) poison damage and becoming stunned until the start of its next turn on a failed save, or blinded until the start of its next turn on a successful one. Creatures which have resistance or immunity to poison damage have advantage on this save.
Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) bludgeoning damage.
Spending most of its life buried almost entirely in soil, a crystalk's luminous antennae attract night-flying insects within reach of its parasol-like ears, capable of absorbing nutrients through their adhesive outer surfaces. Only under the glow of the full moon does the monster rise to supplement this meager diet, following the breath of sleeping creatures and gingerly worming its slick, rubbery limbs into available orifices to feed on mucus and digestive contents. If discovered during feeding or otherwise threatened, the crystalk unleashes an ear-splitting screech and oozes or forcefully sprays its own sticky, black blood from around its ocular disk. Even at a distance, the acrid stench of the inky substance severely agitates the eyes, nostrils and similarly sensitive membranes of other creatures, and close contact is debilitatingly painful. As its attacker doubles over in agony or flees, the crystalk makes a nonchalant and leisurely escape.
