Each time the elemental takes cold damage, its speed is reduced by 10 feet until the end of its next turn. \n'b'  Destroyed by Water . If the blood elemental becomes entirely submerged in water, it dissipates and dies instantly. \n'b'  Liquid Form . The elemental can enter a hostile creature\xe2\x80\x99s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing. \n'b'\n'b' Actions \n'b'\n'b'  Multiattack . The elemental makes two slam attacks. \n'b'  Slam .  Melee Weapon Attack : +6 to hit, reach 5 ft., one target.  Hit : 12 (2d8 + 3) bludgeoning damage. \n'b'  Blood Drain (Recharge 4-6) . Each creature in the elemental\xe2\x80\x99s space must make a DC 15  Constitution  saving throw. On a failure, a creature takes 10 (3d6) necrotic damage and, if it is Large or smaller, it is  grappled  (escape DC 13). A  grappled  creature is  restrained  and unable to breathe. If the saving throw is successful, the creature is pushed out of the elemental\xe2\x80\x99s space. The elemental can grapple one Large creature or up to two Medium or smaller creatures at one time. At the start of the elemental\xe2\x80\x99s turn, each target  grappled  by it takes 10 (3d6) necrotic damage. A creature within 5 feet of the elemental can use its action to make a DC 15  Strength  check, freeing a  grappled  creature on a success. When Blood Drain deals 30 or more necrotic damage, the elemental grows in size as though affected by an  enlarge/reduce  spell. This increase in size lasts until the blood elemental finishes a  long rest . \n'b'\n'b' About \n'b' A swirling, bubbling, ambulatory glob of blood the size of a hogshead cask lurches forward. Native to a lake of churning blood on an abyssal plane, blood elementals aren\xe2\x80\x99t typical elementals. \n'b' Blood mages seem able to retain tiny blood elementals as familiars or guardians of some kind, though the exact nature of their bond is a mystery they guard jealously. Many small sects of blood cultists seem to learn the secret, leading some savants to believe that this knowledge is freely shared by priests of Marena and similar dark gods. \n'b'  Drawn to Life . A blood elemental is drawn to movement and absorbs whatever living creatures it finds, increasing its size and power in the process. Though feeding is not necessary to sustain themselves, blood elementals, over time, will shrink unless they consume living creatures. However, their need for prey is relatively slight-once a week to maintain their size. \n'b'  Blood Summoning . Offerings of blood and blood magic spells draw blood elementals from their planar homes, with the proper ritual. They also sometimes follow in the wake of certain demons and devils, devouring entire bodies in a matter of hours. \n'b' When a blood elemental feeds, it first removes all liquids, then liquefies and consumes the remaining flesh, and finally sucks out the marrow, leaving behind only dry, reddish bones. \n'b'  Elemental Nature . The blood elemental doesn\xe2\x80\x99t require air, food, drink, or sleep.'
