SPECIAL TRAITS

• Hold Breath. The caoranach can hold its breath for up to 1 hour.
• Keen Senses. The caoranach has advantage on Wisdom (Perception) checks that rely on hearing or smell.
• Innate Spellcasting. The caoranach s innate spellcasting ability is Wisdom (spell save DC 16). The dragon can innately cast the following spells, requiring no material components:
  • 1/Day each: control water, control weather
• Invisible in Water. The caoranach is invisible while fully immersed in water.

ACTIONS

• Multiattack. The caoranach makes two attacks: one with its Bite and one with its Tail Slap.
• Bite. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 41 (6d10 + 8) piercing damage and the target is swallowed if it is a Huge or smaller creature. The swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the caoranach, and it takes 27 (5d10) acid damage at the start of each of the caoranach’s turns. The caoranach can have only one creature swallowed at a time. If the caoranach takes 40 damage or more on a single turn from a creature inside it, the caoranach must succeed on a DC 19 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the caoranach. If the caoranach dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 20 feet of movement, exiting prone.
• Tail Slap. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 26 (4d8 + 8) bludgeoning damage. If the target is a creature, it must succeed on a DC 23 Strength saving throw or be knocked prone. Breath Weapons (Recharge 5 6). The dragon uses one of the following breath weapons.
• Fire Breath. The dragon exhales fire in a 90-foot cone. Each creature in that area must make a DC 19 Dexterity saving throw, taking 71 (13d10) fire damage on a failed save, or half as much damage on a successful one.
• Poison Breath. 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 63 (14d8) acid damage on a failed save, or half as much damage on a successful one.

LEGENDARY ACTIONS

The caoranach can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. The caoranach regains spent legendary actions at the start of its turn.

• Tail. The caoranach makes one Tail attack.
• Bite (Costs 2 Actions). The caoranach makes one Bite attack.
• Despairing Light (Costs 3 Actions). The caoranach s mouth glows. Each creature within 60 feet of the caoranach that can see the light must make a DC 16 Wisdom saving throw or become overcome with despair manifesting as unshakable dread. Until the despair ends, the creature has disadvantage on all saving throws and gains the following flaw: “I’m convinced that I’m going to die.” The creature can attempt to end its despair each time it finishes a long rest, doing so with a successful DC 16 Wisdom saving throw. A calm emotions spell also ends the despair, as does any spell or other magical effect that removes a curse.
