Monster Manual III
Though large and obviously powerful, this winged green creature still evokes a sense of speed and agility. Its dog-shaped head turns quickly from side to side, almost like a bird's. The claws on the ends of its powerful fingers look like more than a match for all but the best armor.
Nycaloths act as elite cavalry in yugoloth armies, swooping down onto enemy flanks and tearing up unsuspecting troops. They pride themselves on their ability to strike without warning, then disappear before the enemy has time to launch a reprisal.
A nycaloth looks like a big gargoyle with powerful bat wings and thick, green skin. All four limbs have razor-sharp claws. The head is vaguely canine, with small webbed ears and horns. Most nycaloths carry large greataxes into battle. An average nycaloth stands 8 feet tall and weighs 800 pounds.
Nycaloths speak Abyssal, Draconic, and Infernal.
Combat
A nycaloth's favorite tactic is to use invisibility to approach an enemy on the ground, then dive in with claws extended. If the opponent survives the attack, the nycaloth grabs it and takes off, grappling the enemy until it can drop it from a great height.
A nycaloth's natural weapons, as well as any weapons it wields, are treated as evil-aligned for the purpose of overcoming damage reduction.
A nycaloth normally attacks using its Power Attack feat, taking a -3 penalty on its attack rolls and gaining a +3 bonus on damage rolls (+6 damage with greataxe).
Bleeding Wounds (Ex): A wound from a nycaloth's claw attack continues to bleed after the injury was inflicted. Each wound bleeds for 1 point of damage per round thereafter. Multiple claw wounds result in cumulative bleeding loss (two wounds deal 2 points of damage per round, and so on). The bleeding can be stopped only by a successful DC 15 Heal check or the application of any cure spell or other healing spell (heal, mass heal, and so on).
Improved Grab (Ex): To use this ability, a nycaloth must hit with both claw attacks. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and can attempt to either deal damage with its claws, rake the grappled target (see below), or use its liftoff ability (see below).
Liftoff (Ex): A nycaloth can only use this ability when airborne. A nycaloth that gets a hold on a nonflying opponent of Medium or smaller size can ascend with the grappled creature. When carrying a medium load (a creature weighing between 267 and 532 pounds), the nycaloth's fly speed drops to 60 feet and it takes a -3 penalty on Hide and Move Silently checks; these penalties worsen to -6 with a heavy load (a creature weighing between 533 and 800 pounds). A nycaloth can't carry a load of more than 800 pounds.
Rake (Ex): Attack bonus +15, damage 1d6+5. A nycaloth that gets a hold can make two rake attacks with its hind legs. This includes using the Power Attack feat to take a -3 penalty on its attack rolls and gain +3 on damage rolls.
Spell-Like Abilities: At will - deeper darkness, desecrate, fear (DC 17), invisibility, mirror image, see invisibility, greater teleport (self plus 50 pounds of objects only).
Summon Yugoloth (Ex): Once per day, a nycaloth can attempt to summon another nycaloth or 1d3 mezzoloths with a 30% chance of success.
Immunities (Ex): Nycaloths are immune to poison and acid.
Telepathy (Su): Nycaloths can communicate telepathically with any creature within 100 feet that has a language.
