Amphibious. The dragon can breathe air and water.

Woodland Stalker. When in a forested area, the dragon has advantage on Stealth checks.


Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 13 (2d10 + 2) piercing damage.

Poison Breath (Recharge 5–6). The dragon exhales poisonous gas in a 15-foot cone. Each creature in that area makes a DC 11 Constitution saving throw , taking 14 (4d6) poison damage on a failed save or half damage on a success. 


While individual dragons have their own personalities and tactics, most rely heavily on their breath weapons. They use them whenever they can, preferably from maximum distance and while flying above their enemies. 

When fighting in the open, dragons often circle above their enemies as they wait for their breath weapons to recharge. They only close to melee if their enemies deal significant damage with ranged attacks, or if they can savage an enemy cut off from its allies. Once bloodied , dragons become more aggressive, attacking with bite and claws when their breath weapons aren’t available.

If a dragon is protecting its lair, it utilizes lair features, traps, allies, and architecture such as escape tunnels to keep up a hit-and-run fight, reappearing only when it has a fully-recharged breath weapon. If the dragon is forced into melee combat, it uses its bite and claws against a single foe. If it has legendary actions like Roar and Wing Attack, it uses them to disperse its other enemies.

If reduced to less than one-fourth its hit points while fighting in the open, a dragon flies away. However, it fights to the death to defend its lair, unless it can regain the upper hand through tricks or bargains.

Green Dragon Lair Features

The save DC for the following effects is 13 + the dragon’s proficiency bonus. Choose or roll one or more of the following lair features:

1 Lingering toxic fumes suffocate intruders. A bloodied creature in the lair makes a Constitution saving throw at the start of each of its turns. On a failure, it has disadvantage on attack rolls until the start of its next turn. On a success, it is immune to this effect for 24 hours.

2 Bloated corpses litter the lair. If a creature disturbs or enters the space of one of these corpses, the corpse erupts with poisonous gas. Creatures within 10 feet of the body make a Constitution saving throw , taking 13 (4d6) poison damage on a failure.

3 Pools of poison are scattered throughout the lair. If the dragon is within 10 feet of a pool, it can use a legendary action to drink from it, at which point it can immediately roll to recharge its breath weapon. It can’t do so again until the end of its next turn.

4 The dragon can use Spit Poison on the ceiling of its lair. When it does, the poison reacts with minerals in the rock and creates a green gas that fills a 40-foot-radius cylinder. The area is heavily obscured to creatures other than the dragon. The gas lasts for 1 minute or until dispersed by a strong wind.

Legends and Lore

With a History or Nature check, characters can learn the following:

DC 10 Green dragons breathe poison gas.

DC 15 Most green dragons are cunning liars that can charm you with their gaze and their deceptive words.

DC 20 Many green dragons have networks of spies and are secret political players.


Green dragons enjoy a reputation as cunning schemers who relish twisting the minds of their prey. Green dragons rarely attack without warning: they enjoy combat more when it’s preceded by the frisson of deceit and fear.

Beguiling Words. Conversing with a green dragon is a mistake. Many find the dragon’s words, an artful mixt of lies and half-truths, nearly irresistible. A creature charmed by a green dragon may reveal closely-held secrets and betray friendships. If a creature appears useful, the dragon will let it go, but the creature’s behavior may be influenced by the dragon’s subtle prompts long after its escape.

Prisoners and Minions. Most green dragons collect interesting prisoners: minstrels to soothe it, nobles to charm and subvert, and knights and warriors to torment with terror and lies. A green dragon values its stable of prisoners almost as much as its actual treasure hoard. 

Only slightly less precious than its prisoners are the dragon’s many minions: the kobolds and other monsters that guard its lair, the forest creatures that report to it, and the agents throughout the world that are bound to it by charms, bribes, or threats.

Playing Politics. Unlike most chromatic dragons, green dragons are intensely interested in humanoid politics. Many a mysterious assassination was funded with wealth from a green dragon’s hoard. Green dragons sometimes even orchestrate conflicts between two rival factions, favoring the side that it believes to be the most venal and destructive.

Enemies of Civilization. A green dragon finds cruel amusement in its schemes, but in the long term its meddling has a more sinister purpose: by sowing discord among the humanoids that rule more settled lands, the dragon weakens those who might stand against a draconic conqueror.
