Change Shape (Su): An avolakia can assume the form of any Small or Medium humanoid.

Poison (Ex): An avolakia delivers its poison (Fortitude save DC 18) with each successful bite attack. The initial damage is 1d6 points of Wisdom damage, and the secondary damage is 2d6 points of Wisdom damage.

Spell-Like Abilities: At will -- chill touch, cause fear, detect magic, disrupt undead, gentle repose, ghoul touch, halt undead, mage hand (humanoid form only), read magic, spectral hand; 3/day -- animate dead, create undead, enervation, vampire touch. Caster level 14th; save DC 16 + spell level.

Suggestion (Sp): When in humanoid form, an avolakia has a melodious and hypnotic voice. By speaking soothingly to any one creature in range that understands its spoken words, the avolakia can create an effect identical to that of a quickened suggestion spell (caster level 10th; Will save DC 19). An opponent in eye contact with the creature while it makes its suggestion takes a -2 penalty on the saving throw. The avolakia can use this ability a number of times per day equal to its Charisma modifier (usually six times per day).

Defensive Aura (Sp): An avolakia has a +6 deflection bonus to Armor Class. This ability is always in effect.

Fire Resistance (Ex): The slime that an avolakia constantly exudes grants it fire resistance 10. It also helps the creature escape more easily (see Skills, below).

Immunities (Su): Because of its close association with undead, the avolakia has developed immunity to cold, disease, energy drain, and paralysis.

Regeneration (Ex): An avolakia takes normal damage from acid, fire, and electricity.

Skills: Because of the slime it constantly exudes, an avolakia gains a +10 competence bonus on Escape Artist checks.
