Overview of D&D Dragons

First thing's first... a quick overview of Wizards of the Coast's dragon species. After all, you would think that a game called "Dungeons and DRAGONS" would have a LOT of stuff on Dragons... right?

Yep. You are VERY right.

The 5e Monster Manualdevotes a whopping 34 pages just to dragons. They are divided into twogroups, each group has 5 types (2 x 5 = ten dragon variants). Each type of dragon has 4 variants based on their age—wyrmlings as the youngest, then young, then adult, and then ancient dragons—witheach ageexhibiting varying statistics and abilities.

Speaking of which... 5e dragons are categorized into chromatic and metallic dragons, each with distinct traits and alignments. Chromatic dragons like red, green, black, blue, and white are infamous for their malevolence and greed. On the other hand, metallic dragons such as gold, silver, bronze, copper, and brass are associated with nobility and virtue.

But that's not all! The namesake monsters get an entire BOOK all to themselves: Fizban's Treasury of Dragons. That bestiary not only adds more lore to chromatic and metallic dragons, but introduces a whole new family of dragons... the GEM dragons, as well as tons ofvariants, like sea serpents and elder brain dragons!

The Dragon Species in Dungeons and Dragons

Anyways... where was I? Oh yes... summarizing shared qualities of D&D dragons!

Dragons are the most iconic and (some of) the most powerful creatures infifth edition. They are terrifying, gargantuan monsters thatlaugh at divine smites right before they crush player characters with their paw... or blow you away with a dragon breath... or pick you up and fly way up high before dropping you.

You getthe idea, but here is the sparknotes summary of the similaritiesamong all D&D 5e dragons.

• Size: Baby dragons are medium size, ancient ones are gargantuan. Like, earth-shaking when they walk and blowing you off your feet when they do a jet-fighter-style flyover.
• Age: They can live to be over 1,200 years old, outlasting multiple civilizations around them.
• Ability Scores: Dragons are hella competent. Even the weak wyrmlings have a + to every ability. The older they get, the better they get.
• Saving Throws: Regardless of age, they are proficient in Dexterity, Constitution, Wisdom, and Charisma saving throws (I wasn't kidding when I said these monsters are competent).
• Legendary Saves/Attacks: If the high statsweren't enough, adult and ancientdragons have 3 Legendary Resistances... which means they can just choose to save if they roll bad. That's on top of their 3 Legendary ActionsEVERY ROUND.
• Hit Points: They have a lot. Even if you do damage, it's gonna take a while.
• Flying Speed: They are fasterin the air than on the ground. And most of your party can't fly. If they do not have a reason to land, then they won't/shouldn't.
• Elemental Creatures: They are a blend of a physical creature, magic, and elemental forces. Hence, each has an elemental breath weapon, warps terrainwith their mere presence, and leaves a permanent, magical mark on thelocation of their death.
• Lair and Hoards: Speaking of which... just like dragons in classic fantasy, D&D dragons always make a lair and fiiiiiiill that sucker with a hoard. That hoard can be anything from art to antiques to gold bars... but it is always precious and valuable, most of all to the dragon!

Long story short: dragons are huge, intimidating, terrifying monsters... and they know it. They are not just the embodiment of power, but are also highly intelligent, capable of plotting for centuries and outwitting nations. Hence, their signature trait is PRIDE: all dragons consider themselves the apex race and pity everyone else for not being a dragon.

Fizban's Treasury of Dragons does an excellent job expanding on all the qualities a dragon can have, even adding random encounter tables for personality, hoard, and lair quirks. Thisgives DMs more structured options for customization, for creating truly UNIQUE dragons for their campaigns.

However...

The distinctiveness of these dragons comes at a cost: the more "custom made" a dragon is, the more it is going to deviate from the classic lore. It will stray further and farther from the archetype ofboth its species and, to a greater extent, its type. For example: after all that customization, players might experience the DM's black dragon as something that is more similar to a blue dragon.

And there is nothing wrong with that; I once had acampaign with a metallic and chromatic dragoncouple! But this post is focusing onthe stereotype of a DnD green dragon... how to play and role-play an archetypal Dndgreen dragon.

DnD Green Dragons' Appearance and Stat Block

Now that we have covered the species, let's dive into DnD green dragons in particular!

First thing's first: their physicalappearance, which is distinct. They have longer legs anda longer neck thanothers of their kind. They famously have a crest that spans from their head, along their back, all the wayto the tip of their tail. As they age, green dragon scales go from almost black to bright and vibrant green.

Take a look at the stat block and you'll notice a few things that stand out as unique to DnD green dragons.

There are three things on there that distinguish the DnD green dragon from all other dragons:

• Amphibious: Green dragons are similar to black dragons: they are both land-based and water-based monsters. That is why they have an additional swim speed and can breathe the water in lakes, rivers, and swamps.

• Poisonous Gas Breath: This is the green dragon breath attack. Statistically, poison damage is one of the weaker damagetypes inthe game, but it is surprising that it does not also cause the Poisoned condition, which provides disadvantage on all attacks and saving throws(hint, hint, ruthless dungeon masters...)
• Physical Attacks: The green dragon gets physical attacks like bite, claw, and tail. Additionally, its wing attack, costing 2 legendary actions, adds to its formidable arsenal.

Anancient green dragon is like a nice car that comes with all the bells and whistles. But the younger a dragon is, the less powerful they are. The most notable difference between the old and young is their ability scores and saving throws. Consider STR, which scales down from as high as +8 (!!!) to as low as +2. But along the way, they lose other abilities.Their breath weapon also loses range, and all their attacks do less damage. Young and Wyrmling greendragons have none of the Legendary saves/actions ortheWing Attack ability of their adult and ancient counterparts.

The Poison-Filled Maze of a Green Dragon's Lair

The home of a Dnd green dragon is the place where they can blend in best: forests. Sometimes they are in the cold, evergreen pines of the north... other times they are in the damp jungles of the south. Regardless, where there are lots of trees in Faerun,there are green dragons.

However, they do not just reside there; theyCHANGE the area they dwell in. Green dragons are elemental creatures and the elements are impacted by their presence: the air becomes thicker and smells slightly of chlorine...

• The light, a little darker...
• An emerald fog hangs over the trees...
• The trees shift, forming what feels like a maze...
• The vegetation is thicker,impeding movement...

And the closer you get to the lair, the thicker it all becomes.Within a mile of its lair, these plants becomeso thick that they form walls that block line of sight and require a Dex save to pass through. Birds and rodents increase in number, serving aslittle, living security cameras (and speaker systems) forthe green dragon, and that's on top of the handful of zombiesthe green dragon can manifest!

And strangest for adventurers, once they areless than a mile away from their lair, a green dragon can remove all physical evidence of its passage. And given thatthe lair entrance is often hidden behind a waterfall or barricaded by athick grove of trees or just UNDER WATER... this can make tracking down a green dragon difficult even for a ranger.

But it is within the lair that the elements are not only changed, but actively SERVE the green dragon. They become like the dragon, capable of both natural and physical means, and get lair actions. The fog becomes a gas that will charm PCs if they fail a save. Vines spring forth and graspat player characters' limbs, creating difficult terrain and easy targets for poison gas breath. And if the enemies are too numerous, a hedge of thorny brushappears, creating a wall 60ft long that does damage ifcharacters even attempt to pass through it.

Translation: the closer you get, and especially within a mile of the dragon's lair, the more the environment becomes an ally ofthe green dragon. Soif you can, fight it as far away from the lair as possible!

How to Role-Play a Green Dragon

The 5eMonster Manualdescribes green dragons as highly intelligent, lawful evil monsters that are masters of deception and illusion. They use kindness to disguise their cunning before betraying their prey.

That said...

While that personality singles out DnDgreen dragons from others of their kind... it does NOT single them out from allthe otherDungeons and Dragons monsters:

• They aren't as good at LOOPHOLES as devils.
• They aren't as good at TRICKING as fey.
• They aren't as good at CORRUPTING as hags.

Truth be told... this part is the whole reason I wrote everything else in this blog post. I did some research and hard thinkin' to create a more unique type of enemy for my campaigns. What follows are the distinctive features which I believe will differentiate DnD green dragons from everyother monster in the game, providing a unique TTRPG experience for you and your players.

Sinister Diplomacy

IMO, this is the most important takeaway for having a unique DnD green dragon BBEG. They are masters of aspecific type ofdeception... one that relies on false promises, hiding their own intentions, gathering knowledge and secrets, and pretending to be friends until they are no longer useful. What kind of person is that?

A wicked diplomat.

Green dragons are evil creatures that are masters of diplomacy. Their deception is STRATEGIC, fitting into larger political goals that put them on top. Butthey also have a high emotional intelligence, able to read and charm others into alliances, even if it's against that individual's own values or interests.

Why else do you think they are the only evil dragon that iscapable of living on borders withother groups? It's because they are able to twist words and craft favorable narratives that pit their enemies against one another. They will double cross an ally yet manage to win them back with a calculated explanation.

You are a diplomat... not an outright liar.

So when role-playing a green dragon, you should be constantly deceiving... BUT NOT OUTRIGHT LYING. Do everything to deceive without lying. Use alternative facts, leave information out, appeal to their emotions, redirect their attention from anything that would reveal too much about the green dragon.

So read up on Otto von Bismark and Talleyrand, for THIS is how a DnD green dragon stalks its prey. They hunt humanoids in conversation as much as they do in the forest. But the whole time they are friendly, charismatic, and downright likable!

Illusions and Manipulations

One reason the "diplomat" identity fits so well is because most adventurers would know that a DnD green dragon is bad... yet somehow they are still successful in winning people over. But false diplomacy alone isn't enough to be truly evil. They aren't just winsome... they are MANIPULATIVE.

The definition of manipulation is "harmful influence over someone," and that is exactly what a DnD green dragon does. They are some of the mostclever of dragons, beingmasters of critical thinking as well as displaying great emotional intelligence. So after they earn someone's trust, they will disguise poisonous ideas as curious questions.

Poison their hearts and minds with half truths.

So when role-playing a 5e green dragon, get them to trust you and thenundermine their perception of the world. Be like Palpatine turning Anakin; use questions and innocent statements to tap into their desires and manipulate their emotions. Convince them "I am one of you" and that their former family and allies are the REAL enemies.

And whencaught red-handed, they will gaslight, denying any malice and even play the victim. Their ability to spin long, captivating tales can compel even the most wary travelers to lower their guard.

Ultimately, whatthey are doing is creating an illusory reality, one where they are in control and their victim ispowerless to resist. This is also why I suggest you give your DnD green dragon BBEG a plethora of illusory and enchantment spells to choose from.

Hoard = FakeSophistication?

The hoard of a DnDgreen dragon reveals their kindhearted performance to be a charade. There, players will find all sorts of art, carvings, and rare plants... but most of those will be in a neglected pile.Collecting fine arts becomes a tool of self-deception, allowing them to perpetuate the illusion of refinement. The aesthetic pursuits of green dragons serve as a way to distance themselves fromtheir cruder tendencies, illustrating their complex and multifaceted nature.

Their REALtreasure are those they have so successfully deluded that they are, for all intents and purposes, slaves. Any wizard, scholar, bard, paladin that has been burned by the green dragon and still sees them as a friend is a crown jewel... especially if they choose to remain in the lair!

Asinine Intimidation

Now... if aaaaaall these role-playing attempts have failed, and the players STILL do not trustthe green dragon... then immediately becometheir true nature: rude, immature, crass, spiteful.

The eyes of a red dragon are filled with fury; the DnD green dragon's eyes are filled with DISGUST. Shift from the eloquent, charming diplomat to a thug who is a regular at the strip club. Become loud, obnoxious, and maketerrifying, outrageous threats.

Or... if that's too much energy, forget role-playing and go into combat. Just get them in a closed space and then destroy them with your poison breath!

DnD Green Dragon FAQ

How Do I Use a DnD Green Dragon inCombat Encounters?

Create scenarios where the dragon deploys its followers to construct a labyrinth of poison, obstructing adventurers,outmaneuvering and manipulating unsuspecting adventurers, and gain anadvantageous position. Utilizethickets, vines, and rodents as obstacles, hindering movement within the dragon's lair.

How DoYou FIGHT a Green Dragon?

This is goodadvice for pretty much all dragons: 1) keep it on the ground, 2) bait it into wasting its breath attack, 3) use save-or-suck spells, 4) cast saving throw spells and force it to use its legendary resistances. Also, the vast majority of dragons only have a +1 to Dex... so use spells that require Dex saving throws!

What Changes Would You Make to the DnD Green Dragon?

I would completely take away the bad temper. Red dragons already do it, and it doesn't match the rest of the 5e green dragon personality. I would also lean into the diplomacy by makingthem EAGER to cooperate, knowing that the more complex it is, the higher the likelihood they will be able to pull the strings and come out on top. Also... give them Polymorph likethesilver dragons!

What AreCommon 5e Green Dragon Minions?

All dragons like to have kobolds, orcs, and drakes around, butthe green dragon can go a step further: any smart, talented creature they have corrupted (wizard, paladin, bard) would linger in their lair. They can even get a nearby black dragon to serve them!

WhoAre the Green Dragon's Enemies?

Wood elves.Green dragons freaking HATE them... almost as much as the drow. They also despite hill giants, other rival dragons (likely red, black, white, gold, and copper), and are wary of local green hags. They are also a bit afraid of dwarves, who are resistant to their poisonous cloud.

What Are Some 5e Green Dragon Spells?

I would give the DnD green dragon monster several uses of Major Image, Dominate Person, Detect Thoughts, and Mass Suggestion (see those 5e spells here). This would be homebrew, but it is notable that the Green Abishai... which is a draconic devil that serves Tiamat... is a master of illusory magic.Given the green dragon's emphasis on deception, this makes perfect sense.

Who Are Some Famous DnD Green Dragons?

Claugiyliamatar was famous for living in a city... and tricking House Brokengulf out of its fortune. Aglaraerose ate a wizard and absorbed their magical abilities. And Cyan Bloodbane manipulated much stronger dragons to his advantage.

What is a DnD 5e Dragon's Weakness?

RAW, the green dragon has ZERO weaknesses. However, it would make sense that anyone with high insight (see through the charade) and true sight (see through illusions) would pose a particular threat to them. And in combat, any location with high winds would make it A) hard to fly and B) reduce the effectiveness of their poison breath.

Conclusion: Green Dragon 5e

DnD Green Dragons arepowerful like all dragons. What sets them apart is their deceptive diplomacy, which allows them to manipulate others. They hide their crass and selfish, evil ways with a performance of good nature.

Use this guide to upgrade the green dragon in your games, whether that be a homebrewed world or the dreaded, TPK-threatening Venomfang from the beginner's module "Lost Mines of Phandelver"!
