Nycaloth

Nycaloths, also known as nycadaemons, nycademons, and sky demons,  were the elite air cavalry in yugoloth armies, swooping down onto enemy flanks and tearing up unsuspecting troops. They were the lowest of the greater yugoloths and bitterly resented it, constantly scheming to ascend to greater status and prestige.

Description
Nycaloths were large gargoylish creatures that were feet in height and width, and weighed 800 pounds (362.8 kilograms). Their more traditionally fiendish appearance was made more fearsome by their thick, rippling muscles. They were hulking yugoloths with tough, leathery, light green skin and powerful bat wings but nonetheless moved with astonishing swiftness. Their heads were vaguely canine in shape, and it quickly darted from side to side like that of a bird, hosting a pair of horns and webbed ears.

Reports on the numbers of arms they possessed were variable with some claiming one pair and the others stating two. Regardless, all of their digits ended in weighty, sharp claws seemingly able to cut through flesh and armor with ease. Most were seen carrying large greataxes, clenched in their horned fists.

The females and males of the race were identical enough that other races couldn't distinguish them.

Personality
Nycaloths were cruel, calculating, and controlling, acting with caution to ensure maximum personal benefit regardless of who had to be hurt in order to achieve it. They constantly schemed in order to garner the favor of their superiors of whose status they envied, bullying lesser yugoloths in order to gain attention. They sought amusement by harassing those confined to the ground but when enraged could exterminate entire companies of mezzoloths and dhergoloths.

Their confidence in their physical power was potentially their greatest flaw, behaving smugly when in the presence of those they believed to lack power but hesitating against those of considerable strength. Despite their flaws they were among the most loyal and cooperative of the yugoloths. So long as an arrangement was mutually beneficial they would willingly work with any evil-aligned beings, and a master that treated them well would find them stalwart in the face of all but the most extreme bribes.

Abilities
Nycaloths were both powerful and fast yugoloths that soared through the sky even when carrying heavy loads. They had such a strong magical resistance that weaker magical items, outside of enchanted weapons, did not work when they used them. Their claws were incredibly sharp, causing wounds to bleed more profusely. They could see all parts of the radiation spectrum allowing them to sense invisible beings, and could telepathically communicate with any basically sentient being. Unlike many of their yugoloth kin, they could travel throughout the Abyss and Nine Hells as well as Gehenna, Carceri, and Hades. If needed they could summon in a small team of mezzoloths, dhergoloths or another nycaloth. Despite their brutish abilities they had access to invisibility and mirror image spells.

Combat
Nycaloths most commonly used weapons and were particularly fond of giant two-headed axes 90% of which were enchanted. They were cunning enough to cleverly utilize what magical items they could wield to great effect and were immune to enchantment spells. They prided themselves on being able to suddenly strike without warning before teleporting, or using their other spells to confuse their opponents and disappear without warning. Their preferred tactic was to rush enemies under the guise of invisibility before savaging them with their claws. If the foe managed to survive then they would try to soar into the sky with the opponent in hand before dropping them from the air and hoping they'd die from the fall.

Society
Nycaloths served as the elite air-force among the yugoloths, with commanders winning their status by virtue of power and toughness. They were often called sky demons due to their tactic of bringing foes into the air in order to let them plummet to their deaths. Their pragmatic exploitation and domineering attitudes caused many creatures of the Lower Planes to avoid them, including night hags, most demons, as well as lesser and greater devils. Although they were loyal, powerful, intelligent, and mercenary enough to work with practically anyone, their infuriating superiority complex caused their alliances to be brief.

They had the innate ability to travel to any of the lower planes at will and commonly traveled to the Nine Hells and the Abyss in order to scout the Blood War. They watched the battlefields and reported directly to the arcanaloths, allowing them their superiors to properly negotiate contracts and allocate the yugoloth's resources so that the ultroloths in turn could plot their next move. Supposedly they were also responsible for signaling when the yugoloth forces were to betray their current enforcers.

Despite the fact that nycaloths were very crucial and possibly the most powerful of the greater yugoloths, they were afforded the least status. This was because the information they gathered went to further those above them rather than themselves, and only by learning how to properly use information for their own gains could they become arcanaloths.

Ecology
A pair of nycaloths would give birth to triplets, who would be allowed to grow for a hundred days before being forced to fight each other to the death with only the victor being allowed to live. They were suspected to once be scavengers despite their current predatory nature, as they seemingly enjoyed rotten meat.

Notable Nycaloths
The nycaloths Aulmpiter, Gaulguth, and Malimshaer led the Army of Darkness against Myth Drannor in 714 DR.

Sometime in the late 15th century DR, a nycaloth had been imprisoned in the Tomb of the Nine Gods on Chult by Acererak in order to guard one of the components of the Soulmonger machinery
