The dragon can breathe air and water. \n'b'  Innate Spellcasting . The dragon\xe2\x80\x99s spell casting ability is  Intelligence  (spell save DC 20). It can innately cast the following spells, requiring no material components:\n'b'\n'b'\n'b'  At will :  control water ,  detect magic ,  mage hand ,  prestidigitation  \n'b'  3/day each :  color spray ,  invisibility , obscuring mist \n'b'  1/day each :  control weather ,  sleet storm ,  teleport  \n'b'\n'b'  Legendary Resistance  (3/Day). If the dragon fails a saving throw, it can choose to succeed instead. \n'b'  Siege Monster . The dragon deals double damage to objects and structures. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws. \n'b'  Bite .  Melee Weapon Attack : +10 to hit, 15 ft. reach, one target.  Hit : 32 (4d10 + 10) piercing damage plus 9 (2d8) acid damage. \n'b'  Claw .  Melee Weapon Attack : +10 to hit, 15 ft. reach, one target.  Hit : 13 (1d6 + 10) slashing damage. \n'b'  Tail .  Melee Weapon Attack : +10 to hit, 15 ft. reach, one target.  Hit : 13 (1d6 + 10) bludgeoning damage. \n'b'  Acid Breath (Recharge 5-6) . The dragon exhales acid in a 90?foot line that is 10 feet wide. Each creature in that line must make a DC 19  Dexterity  saving throw, taking 52 (15d6) acid damage on a failed save, or half as much damage on a successful one. \n'b'  Frightful Presence . Each creature of the dragon\xe2\x80\x99s choice that is within 120 feet of the dragon and aware of it must succeed on a DC 19  Wisdom  saving throw or become  frightened  for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature\xe2\x80\x99s saving throw is successful or the effect ends for it, the creature is immune to the dragon\xe2\x80\x99s Frightful Presence for the next 24 hours. \n'b'  Touch of the Sea (3/day) . The dragon touches an adjacent creature. That creature gains a swim speed of 30 feet for 8 hours. This does not give the creature the ability to breathe underwater. \n'b'\n'b' LEGENDARY ACTIONS \n'b' The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature\xe2\x80\x99s turn. The dragon regains spent legendary actions at the start of its turn. \n'b'\n'b'  Detect . The dragon makes a  Wisdom  ( Perception ) check. \n'b'  Tail Attack . The dragon makes a tail  attack . \n'b'  Wing Attack . The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 19  Dexterity  saving throw or take 13 (2d6 + 10) bludgeoning damage and be forced  prone . The dragon can then fly up to half its flying speed. \n'b'\n'b' ABOUT \n'b' Although not inherently evil, brine dragons have little patience for kindness and philanthropy. As they age, they grow more and more opinionated and obsessed with power-by adult age, a brine dragon counts itself a failure if it doesn\xe2\x80\x99t rule over a collection of \xe2\x80\x9clesser beings\xe2\x80\x9d such as humans, merfolk, locathah, or even sahuagin. Their blue-green neck frills sweep back from their heads, leading to a body of dark, shiny scales and fin-like crests. Brine dragons prefer salt water but can venture into fresh water and onto land in desperation when prey is scarce.'
