Special Ability

Bay (Su): When a yeth hound howls or barks, all creatures except other evil outsiders within a 300-foot spread must succeed at a Will save (DC 12) or become panicked for 2d4 rounds. This is a sonic, mind-affecting fear effect. Whether or not the save is successful, an affected creature is immune to that hound's bay for one day.

Special Ability

Trip (Ex): A yeth hound that hits with its bite attack can attempt to trip the opponent as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the yeth hound.

Special Ability

Flight (Su): A yeth hound can fly as the spell cast by an 11th-level sorcerer, as a free action. A yeth hound that loses this ability falls and can perform only partial actions.

Skills: *A yeth hound receives a +4 racial bonus to Wilderness Lore checks when tracking by scent.

Description
General

Despite their intelligence, yrthaks do not speak.

Combat

An yrthak prefers to attack from the air, strafing the ground with sonic attacks or snatching up and dropping prey (eventually landing to devour the flattened mess).

Special Ability

Sonic Lance (Su): Every 2 rounds, an yrthak can focus sonic energy in a ray up to 60 feet long. This is a ranged touch attack that deals 6d6 points of damage to a single target.

Special Ability

Explosion (Su): The yrthak can fire its sonic lance at the ground, a large rock, a stone wall, or the like to create an explosion of shattered stone. This attack deals 2d6 points of piercing damage to all within 10 feet of the effect's center. This counts as a use of the sonic lance and thus is usable only once every 2 rounds, and never on a round following a sonic lance attack.

Special Ability

Snatch (Ex): An yrthak that hits a Medium-size or smaller creature with a claw attack attempts to start a grapple as a free action without provoking an attack of opportunity. If it gets a hold, it can fly off with its prey and deal automatic claw damage, though it prefers to drop victims from a height. It can drop a snatched creature as a free action, which deals normal falling damage if the yrthak is flying.

Special Ability

Blindsight (Ex): An yrthak can ascertain all foes within 120 feet. Beyond that range it is considered blinded. Yrthaks are invulnerable to gaze attacks, visual effects of spells such as illusions, and other attack forms that rely on sight. An yrthak whose sense of hearing is impaired is effectively blind, treating all targets as totally concealed.

Special Ability

Sonic Vulnerability (Ex): Yrthaks are affected by loud noises and sonic spells (such as ghost sound or silence) and are more susceptible to sound-based attacks, suffering a -2 racial penalty to all saves.

Skills: Yrthaks receive a +4 racial bonus to Listen checks.

Description
General

Yuan-ti speak their own language, plus Common, Draconic, and Abyssal.

Special Ability

Spell-Like Abilities: 1/day-animal trance, cause fear, deeper darkness, entangle, neutralize poison, suggestion, and polymorph other. These abilities are as the spells cast by an 8th-level sorcerer (save DC 13 + spell level).

Special Ability

Psionics (Sp): All yuan-ti can produce the following effects at will:

  • Detect Poison: As the spell cast by a 6th-level sorcerer.
  • Alternate Form: The yuan-ti can assume the form of a Tiny to Large viper. This ability is similar to a shapchange spell cast by a 19th-level sorcerer but allows only viper forms. If the yuan-ti has a poisonous bite of its own, it uses its own or the viper's poison, whichever is more potent.
  • Chameleon Power: The yuan-ti can change the coloration of itself and its equipment to match its surroundings.
  • Produce Acid: The yuan-ti can exude acid from its body, dealing 1d6 points of damage to anything it touches. The acid becomes inert when it leaves the yuan-ti's body.
  • Aversion: The yuan-ti creates a compulsion effect targeting one creature within 30 feet. The subject must succeed at a Will save (DC 17) or gain an aversion to snakes for 10 minutes. Affected subjects must stay at least 20 feet from any snake or yuan-ti, alive or dead; if already within 20 feet, they move away. A subject can overcome the compulsion by succeeding at another DC 17 Will save, but still suffers deep anxiety. This causes a -4 reduction to Dexterity until the effect wears off or the subject is no longer within 20 feet of a snake or yuan-ti. This ability is otherwise similar to antipathy as cast by a 16th-level sorcerer.

Skills: *Yuan-ti using chameleon power receive a +8 circumstance bonus to Hide checks.
