Festerumpt (5e Creature)
Festerupt[edit]
Small monstrosity, unaligned Armor Class 15 (natural armor)
Senses passive Perception 13
Pus Spines. A creature that touches the festerupt or hits it with a melee attack while within 5 feet of it has to avoid being impaled and infected; it must succeed on a DC 13 Dexterity saving throw or begin developing a cyst. At the start of each of its turns and whenever it takes damage, a creature with a cyst must succeed on a DC 12 Constitution saving throw or become incapacitated with pain until the start of its next turn; if the save fails by 5 or more, the target is stunned instead. Each additional cyst increases the DC of this saving throw by +2. ACTIONSSlam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) bludgeoning damage. Festeruption. The festerupt explodes its shell into a barrage of spines and pus. Each creature within 40 feet must make a DC 13 Dexterity saving throw, taking 18 (4d8) poison damage plus 18 (4d8) piercing damage and being knocked prone on a failed save, or half as much damage and not being knocked prone on a success. The festerupt lands prone in a space within 20 feet ; it loses its shell, receiving a -3 AC penalty and losing its Pus Spines feature until it grows a new shell in 6 (1d4 + 4) months.

The festerupt is closely related to the pestulump and the scabberant, but much more mobile, more compact and encased in a tougher, spherical shell formed from countless layers of hardened blisters and scar tissue. Its many sharp, movable spines are actually dense formations of hair, sheathed in delicate blister sacs that slide along each shaft to drench the wicked spear with infectious pus. Organisms "stung" by a festerupt are invaded immediately by its symbiotic microorganisms, which feed, multiply and die rapidly enough to develop a large, painful abscess within minutes. The agonizing cyst not only burdens the host with a sensitive new weak point, but continues to grow and concentrate volatile microbial toxins until the slightest injury triggers an explosion violent enough to sometimes kill the host outright. It isn't uncommon for a festerupt to sting a larger monster several times as it sleeps and tail it for as long as necessary, waiting for the cysts to burst and provide it with a fresh carcass to scavenge. |
