Ah – Green! The color of plants and She-Hulk, Spring and infections. Also the color of nasty reptilian beasts who belch chlorine gas. Enjoy some variations on the green dragon …

Moss Dragon: The moss dragon is a small green dragon with a serious inferiority complex. A bully, it lurks near rivers and streams, its grey scales mottled with green looking like a moss-covered boulder, and then jumps out at travelers demanding their lunch money. They dwell in burrows dug into river banks. The entrance to the burrow is always submerged, while the main dwelling cave is above the water table (well, most of the time). Moss dragons breath a pale green vapor that condenses on the skin (or armor) as green slime. The cloud is 30-ft in diameter. All within must pass a saving throw or be struck by a green slime (with all the fun that entails). Moss dragons only have a 25% chance of speaking, but the normal chance of magic-user if they do speak.

MOSS DRAGON: HD 7 (28 hp); AC 2 [17]; Atk 2 claws (1d6), 1 bite (2d10); Move 9 (Fly 24); Save 9; CL/XP 10/1400; Special: Camouflage (surprise on 3 in 6), slime breath.

Chartreuse Dragon: Chartreuse dragons are large brutes, with a tortoise-shaped body (no shell) and a wicked sense of humor. Chartreuse dragons enjoy luxury and decadence – the heady scent of exotic perfumes, rare delicacies, soft silk cushions, etc. Their eyes, large and golden, can hypnotize and command humanoids (save at -2 vs. charm monster), and people enslaved are used to construct wooden palaces in hard-to-find places. A chartreuse dragon has an 85% chance of speech, but only a 5% chance for magic-use, as their lazy minds are rarely up to the mental contortions and acrobatics needed to bend reality. Their breath is an acidic fog that covers a 60-ft diameter area and deals 1d6 points of damage per round to everyone and everything in the vicinity. Assume that armor can suffer 2 points of damage per armor bonus before it is useless, and weapons damage equal to their own maximum damage output. Magical items are unaffected by this acid. A chartreuse dragon’s acid breath has reduced more than a few adventurers to Frazetta-esque nudity!

CHARTREUSE DRAGON: HD 9 (36 hp); AC 2 [17]; Atk 2 claws (1d6), 1 bite (2d10); Move 9 (Fly 24); Save 6; CL/XP 11/1700; Special: Breathes poison gas.

Celadon Dragon: These medium-sized beasts dwell in the tree tops. They have sinuous bodies, like constrictors, with stubby legs that are tipped with long claws for climbing trees. They have two rows of spines on their backs that are connected with a thin membrane. When held close to their bodies, they nearly disappear, but when unfurled they look like sails, and allow the beast to glide and fly. Celadon dragons are ill-tempered brutes that kill as much for the fun of it as for practical reasons. Celadon dragons always speak, but they never cast spells. Their poisonous cloud breath (50-ft diameter) causes half normal breath damage and robs people of 1d4+1 points of strength, dexterity and constitution as it sears their lungs. While the hit point damage from a celadon dragon’s breath cannot be reduced with a saving throw, the ability score damage can be so negated. Lost ability score points are regained at the rate of 1 point per night of complete rest. Points not regained after one week are lost permanently.

CELADON DRAGON: HD 8 (32 hp); AC 2 [17]; Atk 2 claws (1d8), 1 bite (2d10); Move 9 (Fly 18); Save 8; CL/XP 10/1400; Special: Poison gas.

Beryl Dragon: Beryl dragons are large, overbearing know-it-alls. More neutral than chaotic, they are always capable of speech, though rarely capable of interesting speech. Beryl dragons are sages (per the rules for sages) with a pedantic, superior attitude. They stock their lairs with scrolls and books and sometimes resort to chaining humanoid sages to the walls as a sort of living reference source. Beryl dragons are severely near-sighted, making escaping their attention at long distance somewhat easy. They are always magic-users, with the normal complement of green dragon spells plus the following: Detect magic (at will), ESP (at will), legend lore (1/day) and sleep (1/day). They can communicate telepathically up to a range of 100 feet. The gas exhaled by a beryl dragon is a vivid green and covers a diameter of 30 feet. Creatures within the gas must pass a saving throw or lose their memories for 24 hours. During this time, their effective class level and hit points are reduced to one half (i.e. they retain some of their skill, but not all of it).

BERYL DRAGON: HD 9 (36 hp); AC 2 [17]; Atk 2 claws (1d6), 1 bite (2d10); Move 9 (Fly 24); Save 6; CL/XP 12/2000; Special: Forgetting gas, spells.

Viridian Dragon: These medium-sized green dragons live among rocky places in small caves, curing their snake-like bodies into a coil. They are extremely greedy and paranoid, though not entirely evil – some even become boon companions of similarly greedy people provided the dragon always gets the first choice and largest share of discovered treasure. Viridian dragons bury their treasure in multiple locations around their lair and cannot be forced to divulge its location by anything less than a wish (and a saving throw applies here to force the truth out of them). A viridian dragon’s breath is like a powerful drug. It makes people who fail a saving throw immune to fear and besets them with powerful, frightening hallucinations (per the nightmare spell, only while awake). These effects last for 2d6 hours and are then followed by withdrawal symptoms for 1d6 days minus a victim’s constitution bonus. Withdrawals include chills, nausea and an aching neck and shoulders. Viridian dragons have the normal green dragon chance for speaking and magic-use.

VIRIDIAN DRAGON: HD 8 (32 hp); AC 2 [17]; Atk 2 claws (1d6), 1 bite (2d8); Move 9 (Fly 18); Save 8; CL/XP 10/1400; Special: Hallucinogenic gas.

Harlequin Dragon: Harlequin dragons are small, feral looking beasts that dwell in mountain caves overlooking tracts of woodland. Harlequin dragons always look like their grinning, but this is just a trick of their anatomy, for they are morose and moody things that despise life. Harlequin dragons have the normal chance to speak for green dragons, but no chance to cast spells in the normal sense. All harlequin dragons, however, are capable of summoning the local wildlife (say, 1d3+3 wolves or 1d3 brown bears) once per day and they can command and speak with plants. Their poisonous breath covers the same diameter as a green dragon’s (50 feet) but causes uncontrollable laughter (as the spell) rather than damage.

HARLEQUIN DRAGON: HD 7 (28 hp); AC 2 [17]; Atk 2 claws (1d6), 1 bite (2d8); Move 12 (Fly 24); Save 9; CL/XP 10/1400; Special: Command plants and animals, laughing gas breath.

Here are six cousins to the venerable blue dragon.

Azure Dragon: An azure dragon’s sense of self-worth is as majestic as the color of its scales. Azure dragons are mesa dwellers – haughty and self-satisfied. They control the weather over their domains, alternately keeping it dry as dust to discourage large interlopers from approaching and then, when fools dare tread on their domain, causing downpours that turn into flash floods. Azure dragons are medium-sized for blue dragons, with lofty, white horns that curl and nearly meet above its head. Azure dragons are always capable of speech (usually a throaty, superior baritone) and magic. They can always use the following spells: Control weather (at will), call lightning (at will) and lightning bolt (3/day).

| Azure Dragon: HD 9; AC 2 [17]; Atk 2 claws (1d6), 1 bite (3d8); Move 9 (F24); Save 6; CL/XP 11/1700; Special: Spells, control weather, call lightning and lightning bolt.

Cerulean Dragon: Cerulean dragons are small for blue dragons, with tiny scales and over-sized wings. They are gregarious and vivacious, and the least wicked of the blue dragons, though they are as self-centered as any other wyrm, and prefer to be the center of attention. Electricity runs up and down their scales (touching them inflicts 1d4 points of damage) and their bodies give off an electric hum. They are capable of controlling electro-magnetic forces around their body (treat as double-strength telekinesis that only works on iron-based objects). Most cerulean dragons keep dozens of steel blades around their lairs, whipping them into a blade barrier when intruders approach. The blade barrier has a radius of 20 feet and inflicts 8d6 points of damage to anyone who passes through the barrier. They have the normal chances for speech and magic use.

| Cerulean Dragon: HD 8; AC 2 [17]; Atk 2 claws (1d6), 1 bite (3d6); Move 9 (F24); Save 7; CL/XP 11/1700; Special: Magnetism, blade barrier.

Glaucus Dragon: Small, wiry and suspicious, the glaucus dragon likes to toy with its prey. It always acts as though it is incapable of speech and magic use, and always pretends to be sleeping when first encountered. The beast breathes a heady, thick gas – as thick as pea soup – that forces those who breathe it in to pass a saving throw or be struck by the slow spell and age 1d10 years per round. The cloud covers an area measuring 20-feet in radius. This aging can be reversed with a potion consisting of the offending dragon’s blood mixed with blueberries and stirred with electrified copper. They have the normal chance for a blue dragon to speak and use magic.

| Glaucus Dragon: HD 8; AC 1 [18]; Atk 2 claws (1d6), 1 bite (3d6); Move 12 (F27); Save 8; CL/XP 11/1700; Special: Breath weapon (aging).

Indigo Dragon: Indigo dragons are large and lazy – almost floppy if that’s possible for a dragon. They have small, useless wings on their shoulders and terrific maws filled with sharp teeth and two elephantine tusks that jut out of their mouths. Indigo dragon are gluttonous and boorish. They have only a 45% chance to speak, and when they can speak they rarely have anything interesting to say. Indigo dragons radiate an aura of static electricity down the spines on their back. This electricity arcs to any creature within 10 feet, inflicting 2d6 damage per round on characters without metal armor and an additional 1d6 damage for characters in metal armor and/or wielding a metal weapon (i.e. 4d6 total for a character in metal armor wielding a metal weapon. Indigo dragons are encountered in their lairs 80% of the time and are asleep about 70% of the time.

| Indigo Dragon: HD 10; AC 2 [17]; Atk 2 claws (1d6), 1 bite (4d6); Move 6; Save 5; CL/XP 12/2000; Special: Electric aura.

Sapphire Dragon: Sapphire Dragons have brilliant, polished scales that look like little teardrop shaped sapphires. They live deep underground and are notoriously fastidious and picky about their surroundings. All sapphire dragons can assume human shape as they wish, usually taking the form of tall, stately men or women with blue-black hair and sapphire blue eyes. They enjoy attention and worship, and often cultivate little cults of beautiful men and women. Sapphire dragons can always communicate telepathically and cast spells, though they sometimes are incapable of physical speech.

A sapphire dragon with spell-casting ability always has the following spells: First Level – Sleep; Second – Level: ESP; Third Level: Suggestion; Fourth Level – Confusion; Fifth Level: Feeblemind. Their breath is a sapphire ray that can be directed at a single victim. The ray causes all of the victim’s synapses to fire, stunning them for one round and leaving them with a pounding headache for the next 24 hours. While suffering from the headache, spellcasters have a 5% chance of their spells failing to materialize.

| Sapphire Dragon: HD 9; AC 2 [17]; Atk 2 claws (1d6), 1 bite (3d8); Move 9 (F18); Save 7; CL/XP 13/2300; Special: Breath weapon (stun), spells, telepathy 100 feet.

Ultramarine Dragon: Ultramarine dragons are large, powerful specimens of dragonhood, with deep blue scales that gleam in the light and absolutely blaze in the moonlight. They have large, knowing eyes and long, overlapping fangs. Ultramarine dragons are imperious and overbearing, and are especially vulnerable to flattery. They are also uncommonly fond of intoxicating beverages, and have been known to keep especially skilled bartenders in their lairs mixing wondrous concoctions.

An ultramarine dragon spits chain lightning. Chain lightning strikes one target initially, then arcs to up to ten other targets who cannot be more than 10 feet apart from one another. Damage is normal on the first target and half normal on all others. Saving throws to halve damage are permitted. If multiple targets fail this saving throw, their minds are switched by the mystic lightning.

| Ultramarine Dragon: HD 10; AC 2[17]; Atk 2 claws (1d6), 1 bite (3d8); Move 9 (Fly 24); Save 5; CL/XP 13/2300; Special: Chain lightning (damage and mind-switching).
