Arboreal dragons are feylike creatures fiercely devoted freedom and goodness for all. They hold in the highest regard and often undertake missions to aid noble heroes struggling in evil lands. These honorable dragons are frequently found enjoying wine and song in the company of elves, fey, and other nature-friendly creatures.

Among the true dragons of the multiverse, arboreal dragons possess the least draconic appearance. They have no horns, no spikes and no back ridges. Tremendous gossamer wings that sway in the wind extend from their backs. Their streamlined bodies are covered in a patchwork of scintillating scales that slowly change in color and hue, They have elf-like eyes of the deepest black. Whether flying or walking, arboreal dragons leave a trail of sparkling mist in their wake. Despite their fragile appearances, though, arboreal dragons are powerful defenders of peace and beauty and are not to be trifled with.

Arboreal dragons speak Celestial, Draconic, Elven, and Sylvan.

Combat

Arboreal dragons are unpredictable opponents, switching randomly between spell-like abilities, breath attacks, and their natural weapons. They often use tactics to scatter opponents and prevent them from coordinating attacks. Arboreal dragons retreat when drastically out-numbered or hard pressed, using baleful polymorph on foes to cover their escape.

Breath Weapon (Su): An arboreal dragon has one breath weapon, a cone of razor-sharp thorns that deal piercing damage. A creature within the cone may make a Reflex save to take half damage.

Alternate Form (Su): A young or older arboreal dragon can assume any animal, fey, or humanoid form of Medium size or smaller as a standard action three times per day. This ability functions as a polymorph spell cast on it by a 10th-level caster, except that the dragon does not regain hit points for changing form and can only assume the form of an animal, fey, or humanoid. The dragon can remain in its animal, fey, or humanoid form until it chooses to assume a new one or its natural form.

Spell-like Abilities: 3/day - telekinesis (young adult or older); baleful polymorph (mature adult or older); 1/day - Otto's irresistible dance (very old or older), polymorph any object (wyrm or older).

Skills: Climb, Spellcraft, and Survival are considered class skills for arboreal dragons.
