The reef  drake  deals double damage to objects and structures. \n'b'  Tunneler . The  drake  can burrow through coral and solid rock at half its burrowing speed and leaves a 10-foot-diameter tunnel in its wake. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The  drake  makes one Bite  attack  and two Slam attacks. \n'b'  Bite .  Melee Weapon Attack : +11 to hit, reach 15 ft., one target.  Hit : 26 (3d12 + 7) slashing damage. \n'b'  Slam .  Melee Weapon Attack : +11 to hit, reach 5 ft., one target.  Hit : 17 (3d6 + 7) bludgeoning damage. \n'b'  Concussive Snap (Recharge 5\xe2\x80\x936) . The reef  drake  snaps its jaws, emitting concussive force in a 90-foot cone. Each creature in that area must make a DC 15  Constitution  saving throw. On a failure, a creature takes 35 (10d6) thunder damage, is pushed up to 15 feet away from the  drake , and stops holding its breath, if was doing so. On a success, a creature takes half as much damage, isn\xe2\x80\x99t pushed, and doesn\xe2\x80\x99t lose its held breath. Constructs and objects and structures have disadvantage on the saving throw. \n'b'\n'b' BONUS ACTIONS \n'b'\n'b'  Reef Stealth . If the reef  drake  is within 10 feet of a coral reef, it can take the  Hide  action. \n'b'  Siege Follow-Through . If a reef  drake  destroys an object or structure, it can make a bite  attack  against a creature it can see within 5 feet of that object or structure. \n'b'\n'b' ABOUT \n'b' An enormous, scaled wyrm bursts from the reef in a flurry of bubbles and jagged rock. Its snout sports an enormous pair of scissor-like mandibles. \n'b' Reef drakes live in coral reefs and submerged cave systems. \n'b' Long centuries under the sea have seen their forms flatten and their limbs shrivel, leaving a  drake  that resembles a centipede more than its terrestrial kin. This odd shape is uniquely suited to the  drake\xe2\x80\x99s  preferred terrain, allowing it to carve out and  hide  in narrow tunnels and choose its prey unseen. \n'b'  Amiable and Ravenous . Reef drakes are, like many of their terrestrial cousins, intelligent creatures fully capable of conversing with others. Often, they will hold long conversations in Draconic with aquatic humanoids, coming off as jovial, amiable, and casual right up until the moment they bite their conversational partner in half. While pleasant creatures to talk to, reef drakes are far more interested in sating their hunger or testing their might than they are even the most pleasant conversation, and they socialize only briefly\xe2\x80\x94even with other reef drakes\xe2\x80\x94preferring their solitude and ambush-tunnels. \n'b'  Jaws of Death . Reef drakes are ambush predators. They memorize shipping lanes and the migration patterns of large fish, nestle into a hiding spot along those routes, and wait for days, weeks, or even months. They strike when they spot their quarry, devouring their prey or shattering ship keels to get at the prey inside. When confronted with a quarry that fights back, a reef  drake  drags the fight into a coral reef, where it can  hide  among the rocks and ambush its foes again and again. On rare occasions, a reef  drake  takes great personal offense at a port in its territory or a ship that has escaped its attacks and attacks a settlement. The  drake\xe2\x80\x99s  concussive snap can collapse buildings and  shatter  ships in dock, but these chaotic attacks can be dangerous for the  drake . While in a settlement, the  drake  has no places to  hide  and may find it difficult to retreat.'
