Maw of Atropus was introduced in "Class Acts—Warlock: Strange Constellations" by Bruce R. Cordell in Dragon #403, an article meant to improve the ability for Star Pact warlocks to use Constitution-based abilities at certain levels. It is a good choice for star pact warlocks as the defense penalty allows others to exploit the newly created weakness. It is a poor choice without this pact. [1]
