Shulns have a ravenous appetite and eat nearly anything they can catch, but their preferred diet consists almost entirely of large invertebrates, especially cave worms. They rely on tiny sensory whiskers that cover their snoutfland allow them to detect subtle movements in the air and ground without the use of vision. When it detects suitable prey, a shuln bites the target at the first opportunity, injecting it with a potent paralytic toxin present in its saliva. So strong is this poison that it is capable of subduing even the near-unstoppable purple worm, making the shuln a valuable (if dangerous) companion to have for anyone making excursions into worm-infested regions of the Darklands. Shulns' notoriously ill-tempered dispositions and their knack for digging into areas of an underground settlement where digging ought not occur makes them frustrating creatures to keep around, but when the alternative is an unpredictable but deadly visit from an enormous, hungry cave worm, the annoyances are well worth the trouble.
