Neutral evil outsider = Malefactor

[Xoham]

Today I got a new soul gem, unfortunately I can't remember from what monster. Does anyone know which monsters are neutral evil outsiders?

Malefactor isn't in the wiki list (http://ddowiki.com/page/Soul_Gems), but then neither is e.g. "Free Spirit" for chaotic neutral outsiders, so that list may be incomplete.

In any case, for those that collect soul gems I've attached the screenshot below:

Yugoloth? Can't recall any other NE outsiders.

Yugoloth? Hag?

Thanks, that is likely it! I was in the Underdark and Sschindylryn and couldn't reconcile it, but I forgot that I'd also done some challenges. I will guess it's from the Extraplanar Palace then.
