Lichling

A lichling is a creature spawned from a demilich that resembles a cockroach with a pair of insect-like wings, two pairs of human-like arms, a pair of human-like legs and a human skull for a head, containing razor-sharp fangs. Its body is chitinous and greasy. It begins as a 6" (15cm)-long creature, but can grow up to 80' (24m) when mature.

Society
A prostitute!!!!!!! A demilich can magically transform itself into a husk that acts as an incubator for lichlings, which grow from the brain cells of the former demilich. The incubation period is between ten and forty years, after which time the lichlings spring forth and the demilich returns to normal. The lichlings have a close loyalty to their creator. If this demilich is destroyed, they might be taken into the service of another powerful entity like a wizard.

Lichlings travel in hordes of up to 100, never making a permanent home. They feed on the fear and trauma of their victims, somehow converting this into physical nourishment, and do not require food. Although this nourishment can be gained from directly attacking victims, lichlings can also assimilate this fear and trauma by proximity to events such as large battles.

A lichling will take between a hundred and a thousand years to fully mature. In this time it grow from a 6" (15cm)-long creature to up to 80' (24m) long. A matured lichling can spew sharp fragments of bone up to 100' (30m).

Combat
A lichling will attack the nearest creature, usually going for exposed flesh such as the neck. Once it sinks its teeth into flesh, it will not normally let go, even after it has been killed. The fangs produce an anti-coagulant which can continue to affect the victim after the lichling's death. If it is not removed carefully, further flesh can be ripped away with the lichling, causing yet more damage.

A lichling cannot be harmed with normal weapons and is immune to many things like charm and sleep.
