This creature darts and weaves with shocking agility for something so massive. It has four saurian legs that each end in a single massive talon. An incredibly long, whiplike stinger thrashes atop the beast, and what must be its head consists of three tentacles that peel back to expose inner surfaces covered with hundreds of sharklike teeth and a gaping circular maw. Arcs of electricity dance over the monster’s pale blue and white skin, and three huge yellow eyes glare from above its mouth.
The dreaded zeugalak is a dangerous predator found on the lower slopes of rugged mountains in tropical regions, although it has been encountered in large underground regions as well. A zeugalak isn’t particularly intelligent, but it is nonetheless a patient and observant monster that defends its chosen territory quite fiercely.
A zeugalak is a nocturnal creature, although sunlight doesn’t impede its sensitive eyesight. Zeugalaks are especially active during thunderstorms, and cavort atop mountain peaks during such weather. Their terrible bellows of delight when they are struck by bolts of lightning can carry for miles. When struck, they use their electrical teleportation ability to teleport high into the clouds above so they can enjoy the long feather fall back to the ground below through the surrounding storm.
A zeugalak is about 26 feet long and weighs about 22,000 pounds.
A zeugalak is fond of initiating combat with a charge attack, although it also uses feather fall to drop down on targets from high ledges. Once in melee, the creature splits its attacks among all targets in reach, using its Combat Reflexes and the incredible reach of its stinger to disrupt spellcasters and any attempts to flank it. It uses its breath weapon against those who try to stay out of its melee reach.
Augmented Critical (Ex): A zeugalak’s tentacles deal ×3 damage on a successful critical hit.
Breath Weapon (Su): 100 ft. line, once every 1d4 rounds, damage 12d6 electricity, Reflex DC 26 half. The save DC is Constitution-based.
Electrical Aura (Su): A zeugalak’s body is constantly shrouded in an aura of electrical energy. Any creature that successfully strikes a zeugalak with a melee weapon or natural weapon takes 1d6 points of electricity damage. Each of a zeugalak’s melee attacks deals an extra 1d6 points of electricity damage on a hit. This additional damage is not multiplied on a critical hit.
Improved Grab (Ex): To use this ability, the zeugalak must hit a creature that is at least two size categories smaller than it with a claw attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple, it establishes a hold and can attempt to pin the opponent in the following round.
Pinning (Ex): A zeugalak that pins an opponent with a claw deals claw damage (1d8+4) and twice its normal electricity damage (2d6) in each round it maintains the pin. While maintaining a pin with its claw, it can continue to attack other targets with its other attacks (and can even pin another target with its other claw).
Poison (Ex): Injury (sting), Fortitude DC 26, initial and secondary damage 1d10 Str. The save DC is Constitution-based.
Electrical Affinity (Su): A zeugalak takes no damage from electricity. Instead, any electricity attack used against a zeugalak (except for an electricity attack that originates from a zeugalak) temporarily grants it 1d4 points of Dexterity. The zeugalak loses these points at the rate of 1 per hour.
Electrical Teleportation (Su): If a zeugalak gains points to its Dexterity from an electricity-based attack, it can instantly teleport (as the spell greater teleport) to the source of the electrical attack. This ability is a free action that does not provoke attacks of opportunity and can be used once per minute. A zeugalak can use this ability even on another creature’s turn.
Feather Fall (Su): At will, a zeugalak can use a feather fall effect (as the spell, caster level 16th) with personal range.
