Planar Bestiary
These horrid things are much like ogre-sized grey millipedes with oversized mandibles and four feathery antennae on their heads. Surprisingly agile, they can make tight turns or bend over backward to retreat down a tunnel or attack something approaching from their rear.
Burrulks have a knack for sensing and digging through the thin places between dimensions. The ravenous things have few natural predators and can easily wreak havoc on unfamiliar ecosystems.
Multiple burrulks—perhaps hatched from the same batch of eggs—commonly hunt the same area, although they don't seem to communicate or coordinate their attacks. When one finds prey, others in the area quickly converge on their location, preferring to attack creatures that are incapacitated by the first burrulk's poison. Often, explorers celebrate and rest too quickly after defeating one burrulk, not realizing that more are about to arrive.
Despite their ability to burrow between planes, some wonder if some fool deliberately spread burrulks between dimensions.
Some enjoy the intoxicating effect of a burrulk's poison, although most creatures find the stuff nasty and unpalatable.
Motive: Hungers for flesh
Environment: The Abyss and other Lower Planes, the Plane of Earth, underground areas on other planes, in groups of two to five
Health: 15
Damage Inflicted: Moderate wound (4 points)
Armor: 3
Movement: Short; short when climbing, immediate when burrowing
Modifications: Perception as level 7; attacks and Speed defense as level 3 due to large size
Combat: A burrulk attacks twice each round with their bite.
When they bite (or when they're threatened), the burrulk releases a dusting of brain-affecting poison from their antennae as part of the same action. Creatures in immediate range that fail a Might defense task can't take actions or move for about a minute. Victims are freed from the poison's effect early if they are damaged or someone else uses an action to shake the victim from their stupor. A creature that succeeds on the defense task is immune to the poison's effect for about a day.
A burrulk is immune to damage from acid and poison.
Interaction: Burrulks are little more than hungry predators.
Use: A planar merchant keeps live burrulks that they move between dimensions to sell freshly concentrated hypnotic burrulk poison. Sometimes, one or two get loose.
GM Intrusion: A character has a severe reaction to the poison, becoming confused, and attacks anyone trying to help them.
