Adult Green Dragon 2014
CR 15 dragon
Huge dragon, chaotic evil
The dragon can breathe air and water.
After the green dragon exhales its Poison Breath, wisps of poisonous gas laced with the alchemical taint that permeates the dragon's body linger around it. While the dragon's Poison Breath is unavailable, each creature that starts its turn within 20 feet of the dragon must succeed on a DC 18 WIS save or be terrified, as the gas causes the creature to experience frightful hallucinations. A terrified creature is frightened, and its speed is reduced to 0.
If the dragon fails a save, it can choose to succeed instead.
Actions
The dragon roars at up to two creatures of its choice within 120 feet of it. Each target must succeed on a DC 16 CHA save or be vulnerable to poison damage until the end of its next turn. A target resistant to poison damage isn't resistant to it for the duration. A target immune to poison damage is still immune to it, even if the target fails the save.
The dragon uses its Frightful Presence. It then makes one Bite attack and two Claw attacks.
The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 19 DEX save or take 13 (2d6+6) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed without provoking opportunity attacks.
Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 17 (2d10+6) piercing damage plus 7 (2d6) poison damage.
Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6+6) slashing damage.
Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 15 (2d8+6) bludgeoning damage.
Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 16 WIS save or be frightened for 1 minute. A creature can repeat the save at the end of each of its turns, ending the effect on itself on a success. If a creature's save is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
The dragon exhales poisonous gas in a 60-foot cone. Each creature in that area must make a DC 18 CON save, taking 56 (16d6) poison damage on a failed save, or half as much damage on a successful one.
