Eloko

If a biloko is lucky enough to consume several spellcasters or other creatures with innate magical abilities, they undergo a subtle transformation over the course of 1 week. Such a fey is known as an eloko, and in addition to their incredible appetite (even by biloko standards), they have the supernatural ability to grow to immense size.

Bilokos are crocodile-snouted fey who stalk the Mwangi Jungle and feast upon the flesh of humanoids. As cunning as they are vicious, bilokos employ deadly traps and guerrilla hunting tactics to capture prey-typically hapless explorers or, occasionally, wayward villagers, many of whom believe bilokos to be cruel ancestral spirits. The most powerful of these creatures, known as elokos, wield potent transformative magic.

Bilokos have a fondness for bells, and the sound of ringing bells often indicates their presence. In addition to carrying and ringing them while out hunting, bilokos sometimes enchant bells with potent magic, or hang them on strings to serve as alarms for their encampments.

Bilokos look like slender but wiry humanoids with crocodile-like heads, rust-colored skin, and blood-red eyes. They eat only the meat of humanoids, though they can survive for extended periods of time on a single meal thanks to their snakelike ability to consume a Medium humanoid creature whole. They do this by unhinging their jaws and slowly swallowing the victim from head to foot. Thanks to their acidic saliva and sharp teeth, a biloko can masticate their food into an easy-to-digest pulp, grinding flesh and bone into a compact mush, even while swallowing; thus, they do not flinch while devouring meals two or three times their own size.

A recently-fed biloko can be easily recognized by their sagging, distended belly. However, despite their slow appearance, the fey is no less dangerous then, as they delight in killing and might have hungry comrades hiding nearby, waiting to feed.
