Challenge  11 (7,200 XP) \n'b' Special Traits \n'b'   Devil\xe2\x80\x99s Sight . Magical  darkness  does not impair the koralk\xe2\x80\x99s darkvision. \n'b'  Magic Resistance . The koralk has advantage on saving throws against spells and other magical effects. \n'b'  Steadfast : The koralk cannot be  frightened  while it can see an allied creature within 30 feet of it. \n'b'  Actions \n'b'   Multiattack . The koralk can make three stinger attacks and two scythe limb attacks. It can also make a bite  attack  if it has a target  grappled . \n'b'  Scythe Limb .  Melee Weapon Attack : +7 to hit, reach 10 ft., one target.  Hit : 16 (2d12 + 3) slashing damage, OR a Medium-sized or smaller target can be  grappled  by the koralk\xe2\x80\x99s smaller, vestigial arms instead (no damage, escape DC 13). \n'b'  Bite .  Melee Weapon Attack : +7to hit, reach 5 ft., one  grappled  target.  Hit : 19 (3d10 + 3) piercing damage. \n'b'  Stinger .  Melee Weapon Attack : +7 to hit, reach 5 ft., one target.  Hit : 12 (2d8 + 3) piercing damage and the target must make a successful DC 15  Constitution  saving throw or become  poisoned . While  poisoned  this way, the target takes 10 (3d6) poison damage at the start of each of its turns, from liquefaction of its innards. A successful save renders the target immune to the koralk\xe2\x80\x99s poison for 24 hours. If a creature dies while  poisoned  by a koralk, its body bursts open, spewing vile liquid and a newly-formed lemure devil. The lemure is under the command of any higher-order devil nearby. The poison can be neutralized by  lesser restoration ,  protection from poison , or comparable magic. If the lemure is killed, the original creature can be restored to life by  resurrection  or comparable magic. \n'b'  About \n'b' Koralk resemble enormous scorpions, but with scythe-like forelimbs and triple tails dripping poison, their diabolical origins are obvious. \n'b' About \n'b'  Shaped by Arbeyach . These fiendish scorpions sprang from the dark imagination of an arch-devil, who twisted them into being from the tormented forms of lemures and demoted devils. The Lord of the Swarm shaped the koralk to not only be annihilators in battle, but also to gather souls from the fallen, bypassing the typical methods of collecting souls and speeding up the influx to feed his war machine. \n'b'  Transforming Poison . Poison from any one of the koralk\xe2\x80\x99s three stingers liquefies the target\xe2\x80\x99s insides in an agonizing transformation. The stung creature swells as its organs, muscle, and skeleton rapidly break down and reform. When the skin casing pops, it releases a spray of gelatinous goo and reveals the form of a lemure, the lowest form of devil. The new lemure is subject to the will of more powerful devils, and its fate from that moment on is the same as any lemure\xe2\x80\x99s. Eventually it will be remolded into a higher form of devil and become another warrior in service to the arch-devils and Arbeyach. Astoundingly, the koralk\xe2\x80\x99s poison can even work this transformation on demons, converting them to the lowest form of devil. \n'b'  Infernal Mounts . A koralk is large and strong enough for Medium-size devils to ride as a mount. They don\xe2\x80\x99t like being used this way, but being devils, they do what they\xe2\x80\x99re told by their betters or suffer the consequences. Arbeyach commands an especially large specimen of koralk, called the Grand Annihilator by his devilish troops. The Prince of Swarms has been seen riding it into battle.'
