Tremorsense (Imprecise) 60 feet
Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
Negative HealingA creature with negative healing draws health from negative energy rather than positive energy. It is damaged by positive damage and is not healed by positive healing effects. It does not take negative damage, and it is healed by negative effects that heal undead.
Swarm MindThis monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.
Swarming Bites
Each enemy in the swarm's space takes 3d6 negative damage (DC 22 basic reflex save).
Creatures that fail this save become Sickened 1 from the swarm's painful bites.
The humble bore worm is a small and simple creature, both biologically and magically. These qualities allow it to adapt rapidly to different environments, some of them quite extreme, and also makes it susceptible to magical radiation and experimentation. Many a Darklands apprentice takes their first steps in the school of transmutation by practicing on these worms, while variations-both natural and cultivated-are scattered about beneath Golarion's surface.
An undead sorcerer in the ghoul-run Darklands city of Nemret Noktoria developed necral worms about 60 years ago by filling an empress bore worm's abandoned exoskeleton with a unique alchemical paste. These undead bore worms radiate the very energies of death, making them surprisingly sophisticated magical batteries. Less pleasant entities often use them as magical tools. Necral worms have the undead trait and negative healing. They substitute negative damage for acid damage in all of their attacks and abilities, and they gain a weakness to positive damage in place of their weakness to water.
