Gelloudes are frightening creatures known for stealing and devouring young children. However, they are just as likely to attack and slay adults, although their preferred targets are children, expectant mothers, and maidens, in that order.

All gelloudes have 12 and 1/2 secret names. These names are: 1) Guloy, 2) Mora, 3) Budzoy, 4) Marmaroy, 5) Petasis, Pelagia, 7) Bordona, 8) Apletoy, 9) Khamodrakaina, 10) Anabardalaia, 11) Psychanaspastria, 12) Paidopniktria, and 12½) Strigla.

A gelloudes is 7 feet tall and weighs 250 to 300 pounds.

Gelloudes speak Abyssal and Common.

Combat

Gelloudes strike with their claws, attempting to grab a victim and pull it close enough to rake with its lower talons while biting and draining its life force.

Bite (Ex): A gelloudes can bite a grappled opponent. With a successful grapple check, the victim takes 1d4+2 points of damage and is subject to the gelloudes’ energy drain.

Energy Drain (Su): Living creatures hit by a gelloudes’ bite attack gain one negative level. The DC is 15 for the Fortitude save to remove a negative level. The save DC is Charisma-based. For each such negative level bestowed, the gelloudes gains 5 temporary hit points.

Improved Grab (Ex): To use this ability, a gelloudes must hit with a claw attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can bite and rake.

Maul (Ex): A gelloudes that hits an opponent with both claw attacks immediately hits with its bite attack.

Rake (Ex): Attack bonus +8 melee, damage 1d8+2.

Tomb-Tainted (Ex): Although magical beasts, gelloudes are harmed by positive energy and healed by negative energy. They are treated as undead for purposes of spells and effects that treat undead differently (such as searing light or Holy Water). A gelloudes may be turned as if it were an undead creature.

Twelve-and-a-half Names (Su): Each gelloudes possesses twelve and 1/2 secret names. As a result, any divination magic that requires knowledge of the target’s name will fail, as will any spells or abilities that require knowledge of a creature’s truename.

Skills: A gelloudes has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim
check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
