Green Dragons

That something so massive as a dragon
might hide is a terror of its own, an
unmasking of the utter worthlessness of humanoid senses before the cruelty and cunning of ages. The creeping suspicion, however, that this malign intelligence might well have guided you to its forest of choked screams for reasons of its own, that any of your dearest allies might long ago have been planted in your life
to bring this fate upon you... this is another
kind of fear altogether, and one your
typical would-be dragonslayer is
altogether unprepared for.

Green Dragon Lore

Arcana DC 15: Green dragons,
though physically imposing in
their own right, tend not to rely as
heavily upon their breath weapon as most
other dragons in combat, perhaps due to the
wide array of defenses, both magical and
natural, against poison available to their enemies, or
perhaps out of reluctance to damage the forest homes
they spend centuries cultivating. Instead, greens rely
on stealth and subterfuge where possible,
using their innate magics to enhance their natural
camouflage and set toxins worming into the wounds of their enemies.
History DC 15: Green dragons often make their lairs near thin spots where the feywild draws near to the Prime Material, both for the variety of bizarre and hostile plants which can only be found in such places, and for the opportunity to torment any unwitting fey that stumble into their realm without bearing proper tribute.
Nature DC 10: When the anger of a green dragon is roused, they can breathe forth a terrible miasma that reacts with the water in skin, eyes, and lungs, transforming it to stinging acid. In addition to this noxious breath, however, a slower and more insidious poison leaches invisibly from their skin, and their fangs drip venom that can eat away at a creature's ability to resist such poisons.
Nature DC 20: The most intensely protective parents of any chromatic species, green dragons have even been known to sacrifice themselves to spare their offspring, and maintain cautiously friendly ties with their children for centuries after leaving the nest.

Green Dragon Hoards

Green dragons treat their entire hoard as a single unified art object, one in which the arrangement tells a vast story of the dragon's cunning, beauty, and might; landscape paintings showing the numinous brutality of unspoiled nature, bas reliefs ripped from unpeopled castles, and skins torn from defeated rivals serve as backdrops for the rare plant varietals, tended by the captive artists, artisans, and scholars that green dragons favor as servants.

Green Dragon Spellcasting

A green dragon spellcaster cumulatively gains access to the following innate spells as it ages, and can spend two of its legendary actions, if available, to cast one of them:

Green Dragon Lairs

Green dragons lair in densely forested areas, particularly those in temperate or tropical climates, and often near thin spots or passageways to the Feywild. Younger ones will often dig their burrows into the hollows of ancient trees or the earth beneath their roots, while the largest of green dragons will sculpt their lairs out of a dense, living matrix of trees, vines, and other foliage.

Green dragons inevitably take control, directly or indirectly, of any humanoid settlements near their lairs, and will often use their residents as envoys or agents to communicate with outsiders, waiting invisibly in the surrounding forest to take their measure before revealing themselves directly.

Design Note: Heroes' Feast. The spell Heroes' Feast warps every high level dragon encounter around itself, but this is especially true for green dragons, who have nearly their whole mechanical package negated by it.

Green dragons know this, however; they fully expect any intelligent creature that intends to kill them to come prepared with it, and have a healthy understanding of their own weaknesses in that respect. Play them as cagey and ruthless as you can manage in that situation, and have them flee the second the players gain the upper hand.

Green Dragon Tactics

In forests, green dragons use their Slithering Shadow, Forestborn, and Adapt Camouflage to keep hidden at a distance from their enemies, using their Silent Snatch to ambush those that come close, fighting for a turn or two, then using their Rampant Growth to cover their retreat as they move back into hiding. They continue this until reduced below half hit points (or a quarter hit points if fighting in their lair), then flee and hide, resting and returning to attack once more for as long as their enemies remain in their forest. If defending their young, however, green dragons invariably fight to the death.

If their enemies attempt to track them, green dragons will set false trails to lure them into other hazards, traps, or otherwise weak tactical positions.

They typically use their breath weapon only when defending their lair, or when assaulting a settlement outside their home forest, positioning themselves to make use of their Vindictive Snap if any affected creatures seem to resist their breath's damage.

Green Dragon Social Encounters

  • An ancient and powerful green dragon is slowly dying of her wounds after defeating a famed dragonslayer, and six of her offspring have flown in from across the continent, each of them promising a king's ransom to any who can save her, and to poison the land and waters of the kingdom for a thousand generations if none step forward to do so. The knowledge of how she was wounded and how she might be saved, however, seems to have died with the slain dragonslayer, and thus far none have been successful.
  • A green dragon arrives at the celebration of a prince's birth and gifts the baby a circlet of incredible magical power, which seems now firmly affixed to his head and can't be removed by any ordinary means. The prince's adult siblings have all taken this as an implicit threat and have sequestered themselves, each fearing both what this might mean for them and how their siblings might attempt to use the event to their own advantage.
  • A team of dungeon-delvers have discovered an archaic text that purports to be a recipe for a Draught of Strength Eternal. Unfortunately, it requires the nectar of a plant which takes near a thousand years to mature, and which elven horticulturists assert hasn't been seen since the time of the Fourth Crown War, near twelve thousand years ago. A secretive clan of green dragon is said to have maintained a vast arboretum of such ancient plants since the Dawn Ages, though only those with truly exotic plants to trade in have ever managed to successfully contact them, and if any have seen their lair, none have spoken of it.

Blood to Vitriol

6th-level transmutation

  • Casting Time: 1 action
  • Range: 60 ft.
  • Components: V, S, M (flesh scarred by acid)
  • Duration: 1 minute, concentration

You attempt to turn a creature's blood to acid. One creature you can see within 60 ft. must succeed on a Constitution saving throw or be Stunned for 1 minute.

  • Casting Time: 1 action
  • Range: 60 ft.
  • Components: V, S
  • Duration: 10 minutes

You weave a magical snare, sculpted to disrupt a specific spell. Choose a spell in secret. When a creature within 60 feet of you casts that spell, you can reveal your choice to end this spell and to gain control of the triggering spell, selecting new targets for it.

Taste The Air

3rd-level divination

  • Casting Time: 1 bonus action
  • Range: Self (60 ft. radius)

Until the end of your next turn, each affected creature cannot be Hidden from you, and you ignore the effects of Invisibility on that creature.
