Adult Kendermore Brass Dragon

Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.

Aura of Inspiration. Friendly creatures within 30 feet of the dragon gain a 1d4 bonus on attack rolls and saving throws while the dragon is conscious.

Burning Aura. A creature that starts its turn within 10 ft. of the dragon takes 3 (1d6) fire damage.

Multiattack. The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 22 (4d6 + 8) piercing damage + 1 fire damage.

Claw. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 19 (2d10 + 8) slashing damage.

Tail. Melee Weapon Attack: +13 to hit, reach 20 ft., one target. Hit: 21 (2d12 + 8) bludgeoning damage.

Frightful Presence. Each creature of the dragon's 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's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.

This Reminds Me… The dragon begins telling a story that lasts until the end of its next turn. While the dragon is telling a story, it cannot use its breath weapons, and a creature that can hear the dragon and attempts to target the dragon with an attack or harmful spell must first make a DC 17 Wisdom saving throw. On a failed save, the creature must choose a new target or lose the attack or spell.

The dragon can continue the story as a bonus action on each of its turns, extending the duration until the end of its following turn.

Breath Weapons (Recharge 5–6). The dragon uses one of the following breath weapons.

Fire Breath. The dragon exhales fire in an 65-foot line that is 10 feet wide. Each creature in that line must make a DC 21 Dexterity saving throw, taking 73 (21d6) fire damage on a failed save, or half as much damage on a successful one.

Sleep Breath. The dragon exhales sleep gas in a 65-foot cone. Each creature in that area must succeed on a DC 20 Constitution saving throw or fall unconscious for 10 minutes. This effect ends for a creature if the creature takes damage or someone uses an action to wake it.

Change Shape. The dragon magically polymorphs into a humanoid or beast that has a challenge rating no higher than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the dragon's choice).

In a new form, the dragon retains its alignment, hit points, Hit Dice, ability to speak, proficiencies, Legendary Resistance, lair actions, and Intelligence, Wisdom, and Charisma scores, as well as this action. Its statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.

Innate Spellcasting. The dragon's spellcasting ability is Charisma (spell save DC 17, +10 to hit with spell attacks). The dragon can innately cast the following spells, requiring only verbal components:

At Will: friends, message, see invisibility, create or destroy water, speak with animals

2/day each: magic mouth, sending, charm monster, detect thoughts, wall of sand

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's turn. The dragon regains spent legendary actions at the start of its turn.

Detect. The dragon makes a Wisdom (Perception) check.

Tail Attack. The dragon makes a tail attack.

Calm The Unruly. The dragon shoots a wilting glare at one creature within 30 ft, ending one condition affecting it. The condition can be Charmed, Frightened, Hasted, Polymorphed, or Raging.

Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 21 Dexterity saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
