Tyrannabyss Species in Alcirya | World Anvil

Tyrannabyss

The tyrannabyss inhabits coastal waters - especially reefs and rocky shoals - where it prowls the sea floor in search of prey. It can swim rapidly for short distances by undulations of its body. Its circular mouth is lined with rasping teeth. If its prey is hit by both clawed tentacles (d4 hp damage each), it is drawn up against this orifice for an automatic d6 hp damage per round of contact. This mouth can rasp through armor at a rate equal in rounds to the difference between the AC and 10. For example, chain mail (AC 5) requires 5 rounds before actual damage to the victim results, while plate mail (AC 3) requires 7 rounds. If the victim breaks away before it takes any personal injury, damage to the armor still takes place.

Below the mouth of the tyrannabyss is its primary hunting weapon, an elongating tube that can fire a barbed sting to a range of 10'. Its sting paralyzes (save negates) its prey and the tube is retracted to draw its victim within range of its tentacles. If the saving throw is made, victims with a strength of 15 or better can resist the pulling tube, but take 1 hp damage per round due to the lacerations from the barbed sting. The sting can only he used once; then, 3 rounds are required for it to be rearmed.

The tyrannabyss is covered with a thick coat of mucous which allows it to withstand prolonged periods out of water, if it can stay damp. The tyrannabyss has been reported to attach itself to the bottom of boats with its numerous suckers and prey upon the crew above. Its soft back is AC 8, while its under, side, tentacles, eyestalks, and sting are AC 6. Blunt weapons do only half damage, while edged weapons and fire do full damage. If injured but not slain, the tyrannabyss can regenerate 1 hp per turn in seawater. It has the ability to assume the coloration of its surroundings and its boneless body can squeeze through openings considerably smaller than its body size. It cannot squeeze under doors or through small cracks. If a man can crawl through an opening, so can a tyrannabyss.
