Planar Bestiary
Looking much like a huge, stony star-nosed mole covered in metal spines, a delurazon is a casual hunter on the Plane of Earth and adjacent planes, digging tunnels to search for living creatures, metals, and raw gemstones, which they eat as food.
Although it's common for a delurazon to simply pass by or over a creature that isn't in their direct path, sometimes they sense something especially flavorful nearby and relentlessly pursue that prey for several minutes. The delurazon continues to eat other things even as they chase this chosen prey.
Delurazons often attract multiple xorn (bizarre natives of the Plane of Earth with trigonal body configuration), trailing these creatures in their wake as they crawl and dig through the ancient rock of their home plane. The two kinds of creatures do not appear to communicate, and the delurazon sometimes bites a xorn that gets too close to their face, but otherwise the xorn seem content to roam near the much larger creature, sometimes gobbling up items the great beast ignores or that pass through their digestive tract.
Motive: Hungers for minerals and gems
Environment: The Plane of Earth, anywhere underground near precious veins of metal or gemstone, either alone or in the company of two or three xorn
Health: 22
Damage Inflicted: Moderate wound (4 points)
Armor: 2
Movement: Short; short when burrowing
Modifications: Speed defense as level 4 due to huge size; perception tasks using smell to pinpoint precious metals and stones within short range as level 10; resisting tricks as level 3
Combat: A delurazon attacks three times each round, once with their bite and twice with tendrils.
A target struck by a tendril is grabbed and can't move until they can escape.
If the delurazon bites a creature already grabbed in one tendril, the attack is eased, and instead of taking damage on a hit, the target is swallowed.
A swallowed target takes 10 points of damage each round from the digestion process. All the physical tasks of a swallowed creature are hindered but they can attack from within if wielding a weapon. If the delurazon takes 6 points of damage or more on a single turn from the swallowed creature, the delurazon regurgitates the victim, which falls prone in front of them. A swallowed creature can also wiggle free of a dead delurazon.
Just being near a delurazon is hazardous; a creature that touches the delurazon or hits them with a melee attack takes 4 points of damage from their spiky body.
Interaction: A delurazon isn't intelligent but could be lured by precious minerals or gems.
Use: A nearby noble's vaults have been breached by several elemental creatures, including one as large as an elephant that looks like a mole. The creatures are intent on eating all the riches of the noble unless someone is brave enough to drive them off or kill them.
GM Intrusion: The delurazon, reacting to an attack by a character, simply sits on the character, pinning them beneath their great bulk until the character can escape. The pinned character automatically takes 4 points of damage each round from being crushed.
