Prehensile Tail. If the dragon succeeds on a tail attack, it may force the target to make a DC 16 Strength saving throw or be grappled.

Camouflage (3/Short Rest). The dragon changes the color of its scales to match its surrounding environment for 1d10 rounds. While camouflaged, the dragon has advantage on all Dexterity (Stealth) checks, and creatures attacking the dragon have disadvantage on attack rolls. If the dragon takes damage or is exposed to Hideous Zippleback gas, it must make a concentration check or lose the effect.

Hypnosis (1/Long Rest). The dragon picks one target, and the dragon's pupils dilate into slits and swirl. If the creature is not blind, it must make a DC 19 Wisdom saving throw. On a failed save, the creature comes completely under the influence of the dragon until the effect is dispelled, and the dragon may implant suggestions in their mind that they then carry out when the spell ends (anything short of suicide). The target gets a saving throw every time the dragon implants a suggestion, and any one successful save breaks the dragon's influence.

Bite. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 2d6 + 6 piercing damage plus 1d8 acid damage.

Tail. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 2d8 + 6 bludgeoning damage.

Acid Breath (8/Short Rest). The dragon exhales acid in a 60-­foot line that is 5 feet wide. Each creature in that line must make a DC 19 Dexterity saving throw, taking 9d8 acid damage on a failed save, or half as much damage on a successful one.

Fire Breath (3/Short Rest). The dragon exhales fire in a 60-foot cone. Each creature in that area must make a DC 17 Dexterity saving throw, taking 6d6 fire damage on a failed save, or half as much on a successful one.
