b'Rot Grub Swarm \n'b'\n'b'  Huge   swarm  of Tiny beasts,  unaligned  \n'b'  Armor Class  9  Hit Points  94 (9d12 + 36)  Speed  20 ft., climb 20 ft.\n'b' STATS STR: 8 (-1) DEX:  15 (+2)  CON:  18 (+4)  INT:  1 (-5)  WIS:  4 (-3)  CHA:  1 (-5)  \n'b'\n'b'\n'b'\n'b'\n'b'\n'b'     Damage Resistances  necrotic, piercing, slashing  Condition Immunities   charmed ,  frightened ,  grappled ,  paralyzed ,  petrified ,  prone ,  restrained , stunned  Senses   blindsight  30 ft., passive  Perception  7  Languages  \xe2\x80\x93  Challenge  5 (1,800 XP) \n'b' Special Traits \n'b'   Spider Climb . The rot grub swarm can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check. \n'b'  Swarm . The swarm can occupy another creature\xe2\x80\x99s space. The swarm can move through any opening wide enough for a Tiny maggot. The swarm cannot regain  hit points  or have  temporary hit points . \n'b'  Actions \n'b'   Bites .  Melee Weapon Attack : +5 to hit, reach 0 ft., one creature in the swarm\xe2\x80\x99s space.  Hit : The target becomes infested by 1d6+2 rot grubs. At the beginning of the infested creature\xe2\x80\x99s turn, it takes 1d6 piercing damage per rot grub infesting it. Application of fire to the wound before the end of the target\xe2\x80\x99s next turn does 1 fire damage and kills those rot grubs. After this, however, the rot grubs have burrowed too deep into the flesh to be affected in this manner. If a creature infested by rot grubs ends its turns at  0 hit points , it dies as the grubs reach its heart and kill it.  Lesser restoration  or other effects that cure disease kill all rot grubs infesting the creature. \n'b'  Engulf . The swarm engulfs a Medium or smaller creature. The engulfed target is considered  grappled  by the swarm (escape DC 10) and becomes  blinded ,  restrained , and unable to breathe. It must succeed on a DC 15  Constitution  saving throw at the start of each of the swarm\xe2\x80\x99s turns or take 13 (2d10 + 2) piercing damage and be infested by 1d6+2 rot grubs (see the bites  attack , above). If the swarm moves, the engulfed target moves with it. The swarm can have up to two creatures engulfed at one time. \n'b'  This wriggling\xc2\xa0mass of horror has been\xc2\xa0devouring the bones of\xc2\xa0the dead to be found in\xc2\xa0this chamber but sensing\xc2\xa0the arrival of fresh prey the\xc2\xa0entire nauseating mass of white worms wriggles forth from the\xc2\xa0puddle to attack.'
