Specter

When an evil mortal creature dies, it sometimes returns to haunt the area of its death as a specter, a hateful remnant, always seeking to slay others-particularly humanoids-in an attempt to distribute its pain among as many souls as it can. A specter maintains a strange semblance of its prior identity, but with a corrupted sense of purpose. It cannot be reasoned with.

A specter denied the opportunity to harm living humanoids grows increasingly agonized and irrational, akin to the mindset of a starving person forever denied a release from agony through death.
