Bralani Eladrin

(From Planescape Monstrous Compendium Appendix II - 1995):

The snowy, sandy wastes of Pelion are home to the bralani eladrins. They’re the wildest and most feral of their kind, existing from heartbeat to heartbeat in a glorious, never-ending passion. No eladrin can match the fury of an angry bralani, or the keening depths of her grief or sorrow, or the blissful heights of her joy. Bralani are tied to the plains of Pelion, but may occasionally be found dancing in the desert winds or arctic wastes of other realms, exulting in their freedom and the beauty of the open land.

Bralani in their natural form resemble short, stocky elves, broad in the shoulders but graceful nonetheless. Their hair is usually a bright silvery-white, and their eyes are an everchanging rainbow of hues that flicker and shift with the vagaries of the bralani’s mood. Bralani can also take the shape of a whirlwind of dust, sand, or snow, racing across their beloved plains like living zephyrs. 

Bralani are the most distant and fey of the eladrins, dangerous to approach and fickle in temperament. Strangers might be greeted with wild celebration or attacked in a towering rage. Although the bralani’s purpose seems to be to dance and race about in the wastes, they’ll drop their endless dance in a moment if they come across evil in their domain. A few rare and unusual bralani sojourning in other worlds ally themselves with the local forces of good, siding with a tribe of noble desert savages or aiding a group of northern herdsmen.

In their native layer of Pelion, the Bralani travel in loose bands in an unending dance of wind and sand. Each day the band travels hundreds of miles, stopping only to play pranks on travelers or deal with any unwanted intruders they find. The bralani don’t acknowledge any one individual as leader. The entire band acts merely on spontaneous impulses, which can make these eladrins very hard to deal with. 

When the bralani leave Pelion, they travel in smal groups of only 1 to 3 individuals. In the rare instances where the bralani have mobilized for war, they act as scouts and skirmishers, harrying the enemy's flanks and rear. 

Combat: In humanoid form, bralani are surprisingly strong: they've got an 18/76 Strength with the resulting bonuses. Bralani prefer the spear, the bow, and the scimitar - weapons of the desert nomads they most closely resemble. Bralani weapons're often enchanted. These folk are superb archers, and gain a +4 bonus to bow attacks due to their great Dexterity and instinctive mastery of the wind. 

However, a bralani's just as likely to abandon his weapons and attack as a living whirlwind. In this form, he's AC -2 and can attack with two scourging sand- or snow-blasts for 1d10 points of damage each. The blasts have a 20-foot range and affect a cone 5' in diameter. Any creature within 20 feet of the bralani in whirlwind form must successfully save versus paralyzation or suffer a -2 to attacks due to stining sand in his eyes. Any man-size or smaller creature that approaches within 5 feet of the bralani in its whirlwind must successfully save versus paralyzation again or be swept off its feet by the raging winds and thrown 10 to 30 feet. Bralani love to careen through an enemy's flanks, knocking their foes left and right as they dance right past them.

In addition to the powers all eladrins possess, bralani can use the following abilities once per round: blur, charm person, control weather, cure disease, gust of wind, mirror image, and wind wall. Twice per day they can cast a lightning bolt (8d8 points of damage), and cure serious wounds or neutralize poison. 

Bralani can be hit only by +1 or better weaponsm or weapons forged of cold-wrought iron. A bralani can gate 1d4 other bralani eladrins to his location with a 40% chance of success.

(From 3.5e Monster Manual I - 2003):

The being before you resembles a short, stocky elf, broad in the shoulders but quick and nimble. Its hair is a bright silver-white, and its eyes are an ever-changing rainbow of hues.

The bralanis are the wildest and most feral of their kind, existing from heartbeat to heartbeat in a glorious, never-ending passion. In addition to their natural form, bralanis can assume the shape of a whirlwind or zephyr of dust, snow, or sand. Bralanis speak Celestial, Infernal, and Draconic, but can communicate with almost any creature, thanks to their tongues ability.

Combat: Bralanis prefer the scimitar and bow, the weapons of the desert nomads they most closely resemble. A bralani’s natural weapons, as well as any weapons it wields, are treated as chaotic-aligned and good-aligned for the purpose of overcoming damage reduction. Spell-Like Abilities: At will— blur, charm person (DC 13), gust of wind (DC 14), mirror image, wind wall; 2/day—lightning bolt (DC 15), cure serious wounds (DC 15). Caster level 6th. The save DCs are Charisma-based. 

Whirlwind Blast (Su): When in whirlwind form, a bralani can attack with a scouring blast of wind, dealing 3d6 points of damage in a 20-foot line (Reflex DC 16 half ). The save DC is Constitution-based. 

Alternate Form (Su): A bralani can shift between its humanoid and whirlwind forms as a standard action. In humanoid form, it cannot fly or use its whirlwind blast, but it can use its spell-like abilities and its weapons. In whirlwind form, it can fly, make slam attacks and whirlwind blast attacks, and use spell-like abilities. A bralani remains in one form until it chooses to assume a new one. A change in form cannot be dispelled, nor does the bralani revert to any particular form when killed. A true seeing spell, however, reveals both forms simultaneously.

• At will: alter self, blur, charm person, comprehend languages, cure wounds, detect evil, gust of wind, mirror image, phantasmal force, wind wall

ACTIONS

Multiattack. In its true form, the bralani makes two scimitar or longbow attacks. In whirlwind form, the bralani uses its Scourging Blast ability twice.

• Scimitar. Melee Weapon Attack: +8 to hit, 5 ft. reach, 1 target. Hit: 11 (2d6 + 4) slashing damage.

• Longbow. Ranged Weapon Attack: +8 to hit, range 150/600, 1 target. Hit: 13 (2d8 + 4) piercing damage.

• Scourging Blast (Whirlwind Form only). A blast of wind and debris forming a line 20 feet long and 5 feet wide shoots from the edge of the whirlwind in a direction the bralani chooses. Each creature in the line must make a DC 13 Strength saving throw, taking 8 (2d6) bludgeoning damage on a failed save, or half as much damage on a successful one.

Summon Eladrin (1/Day). The eladrin chooses what to summon and attempts a magical summoning. A bralani eladrin has a 30 percent chance of summoning one bralani eladrin. A summoned eladrin appears in an unoccupied space within 60 feet of its summoner, acts as an ally of its summoner, and can’t summon other eladrin. It remains for 1 minute, until it or its summoner dies, or until its summoner dismisses it as an action.

Whirlwind Form. The bralani transforms into a large whirlwind of dust, snow, or sand, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed into the new form.

In its whirlwind form, the bralani has an Armor Class of 20, a fly speed of 90 feet, and resistance to bludgeoning, piercing, and slashing attacks from nonmagical weapons. Being incorporeal, the whirlwind cannot wear clothes or equipment, wield any weapons, or cast spells listed in its innate spellcasting.

The whirlwind can enter a hostile creature’s space and stay there, and can move through a space as narrow as 1 inch wide without squeezing. The area within 20 feet of the whirlwind is heavily obscured to all creatures except the bralani.

On the bralani’s turn, it can force up to 3 medium-sized or smaller creatures within 5 feet of the whirlwind to make a DC 13 strength saving throw. On a failure, the creature is flung up to 20 feet away from the whirlwind in a direction of the bralani’s choice and knocked prone. If a thrown creature strikes an object, such as a wall or floor, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was thrown. If thrown at another creature, that creature must succeed on a DC 13 Dexterity saving throw or take the same damage and be knocked prone.
