Flysore (5e Creature)
From D&D Wiki
Tiny plant, neutral
Stench. Any creature that starts its turn within 15 feet of the flysore or moves there for the first time on its turn must succeed on a DC 14 Constitution saving throw or be poisoned until the start of its next turn; if an undead or carrion-eating creature fails this save, it is charmed instead. On a successful saving throw, the creature is immune to the flysore's stench until the end of its next turn.
Swarm Hands. The flysore can use its flies as appendages, and has a reach of 30 feet.
Multiattack. The flysore makes two fly swat attacks.
Fly Swat. Melee Weapon Attack: +6 to hit, reach 30 ft., one target. Hit: 14 (4d6) piercing damage, and the target must succeed on a DC 11 Dexterity save or become blinded and start suffocating until the end of its next turn.
Initially growing as a coconut-sized cyst in the flesh of a host organism, the flysore eventually sloughs off, rolls for some distance and finally bursts open into its "blooming" stage. Comprised of more dead, decaying tissues than living cells, its pus-filled head becomes a nesting site for carrion flies integrated so deeply into its consciousness that they effectively function as compound pseudopoda. Even stationary, a flysore's swarms can reach far across a battlefield, and the monsters make excellent guard beasts; some demons use many flysore together as part of a "moat" around their fortresses.
