Green Dragon Wyrmling

Combat

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.
