Adult Brown Dragon

If a young brown dragon is able to eat its weight in food each day for 2,000 days, it will grow to become an adult brown dragon. At this point the dragon’s appetite has reached legendary levels, and there are few creatures it has not tasted. Its culinary expertise is exceptional, and the dragon is able to divine a tremendous amount of information just by tasting something once. Its obsession with a certain type of food has narrowed to be even more specific. A brand of liquor, certain breed of animal, or specific subrace of humanoid are typically within the range of specificity appropriate for this obsession. While its hunger is no less great, the dragon has learned to live with the discomfort, preferring a quality meal over mindless consumption. An adult brown dragon delights in sharing knowledge of food and drink with others, a disturbing experience to many who would never dream of eating half the things a brown dragon would.

TRAITS

Hyper Metabolism. When the dragon digests a fleshand- blood creature of Small size or larger, it regains 28 (8d6) hit points. A dead creature or a creature at 0 hit points that is swallowed by the dragon is immediately digested.
Juggernaut. If the dragon would be moved from its space, it may take a reaction to prevent that movement. Legendary Resistance (3/Day). When the dragon fails a saving throw, it can choose to succeed instead.


ACTIONS

Multiattack. The dragon makes three attacks: one with its Bite or Munch, and two with its Claw. The dragon may replace one of these attacks with its Challenging Roar.
Bite. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 40 (5d12 + 8) piercing damage. If the target is a creature, it is grappled and restrained (escape DC 22).
Challenging Roar. The dragon roars a mighty challenge to its enemies. Each creature within 120 feet that can hear the roar must succeed on a DC 23 Wisdom saving throw or be compelled to meet the dragon’s challenge for 1 minute. A creature so challenged cannot willingly move away from the dragon and cannot affect creatures other than the dragon with its spells, attacks, or abilities. A creature may repeat its saving throw at the end of each of its turns, ending the effect on a success. A creature immune to the charmed condition is immune to this effect.
Claw. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 24 (3d10 + 8) slashing damage.
Flensing Breath (Recharge 5–6). The dragon exhales a blast of air and sand that tears flesh from bone in a 40-foot line that is 5 feet wide. Each creature in that line must attempt a DC 23 Constitution saving throw or take 72 (16d8) slashing damage, or half as much on a success. A creature that fails the saving throw by 5 or more has its hit point maximum reduced by an equivalent amount. This effect lasts until it takes a short or long rest or receives magical healing from a spell of 6th level or higher.

Munch. Melee Weapon Attack: +15 to hit, reach 5 ft., one Large or smaller creature grappled by the dragon. Hit: The creature is swallowed by the dragon. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the dragon, and it takes 21 (6d6) acid damage and 21 (6d6) bludgeoning damage at the start of each of the dragon’s turns. A creature with 0 hit points that takes this damage is digested. If the dragon takes 30 damage or more on a single turn from a creature inside it, the dragon must succeed on a DC 22 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 dragon. If the dragon dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.
