The umibozu\xe2\x80\x99s spellcasting ability is  Charisma  (spell save DC 21). It can innately cast the following spells, requiring no material components:\n'b'\n'b'\n'b'  3/day :  antilife shell ,  control water  \n'b'  1/day each :  control weather ,  storm of vengeance  \n'b'\n'b'  Untraceable . The umibozu is immune to all spells and effects made to learn its location or gain information about it. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The umibozu makes two slam attacks. \n'b'  Slam .  Melee Weapon Attack : +10 to hit, 20 ft. reach, one target.  Hit : 59 (10d10 + 4) bludgeoning damage. \n'b'  Dooming Gaze . The umibozu can gaze at one creature within 120 feet and attempt to overwhelm its mind with fear. That creature must succeed a DC 19  Wisdom  saving throw or be  paralyzed . A  paralyzed  creature can attempt another saving throw at the end of each of its turns to end this effect. Once a creature that was  paralyzed  breaks free from that condition, they must attempt another DC 19  Wisdom  saving throw or become  frightened  of the umibozu. A frightened creature can attempt another saving throw at the end of each of its turns to end this effect. A creature that is immune to the frightened condition is immune to both effects of this ability. \n'b'  Draining Strike (3/Day) .  Melee Weapon Attack : +10 to hit, 20 ft. reach, one target.  Hit : 117 (18d12) necrotic damage plus the target must succeed a DC 19  Constitution  saving throw or gain 1 negative level. \n'b'  Elusive (1/Day) . The umibozu has long been the stuff of maritime legends, but despite countless attempts to hunt them, they are rarely encountered unless they wish it. While in water, the umibozu can move up to 400 feet in a single movement without leaving any trace of its passing (while under the effects of a  pass without trace  spell). The umibozu gains advantage to its  Dexterity  ( Stealth ) ability checks while making this movement. \n'b'\n'b' ABOUT \n'b' Umibozus are formed from the combined despair and horror of death at sea, such as when a ship sinks and its entire crew drowns. No single restless soul empowers a umibozu-it combines the anger and doom of all who die in such close proximity. Reawakened as mammoth ship-wreckers, these angry spirits have no memory of their past lives and seek to inflict the doom they suffered on others who ply the seas. \n'b' Their hatred does not make them mindless, however, and more than one lucky crew member has talked her entire ship\xe2\x80\x99s way out of total annihilation. Umibozus have an unusual respect for those with wit and guile and sometimes consider sparing those they deem worthy of their esteem. Those who try to defend themselves with brawn and weapons, however, receive no mercy from the enormous monsters. \n'b'  Nothing but Death . A umibozu\xe2\x80\x99s body is black and leathery like that of a squid when seen up close, but an ever-present mist clings to it even in the water, causing it to appear at first glance to be made out of the black waters of the ocean itself, or a bank of shadow and fog rising up from the waves. The entire creature is featureless and smooth, making its empty visage and its two gleaming pinpricks of light for eyes all the more horrifying.'
