Ways to corrupt an elemental

[sambouchah]

Are there any templates I could add to an elemental that would change their alignment to NE or LE?

Thanks, Sam

Edit: Doesn't HAVE to be a template

In Core only, Half-Fiend or Half-Dragon would do it for sure; Skeleton or Zombie might also do it, but only for earth elementals, I think.

Necromental (http://www.wizards.com/default.asp?x=dnd/iw/20041015b&page=3) will do it.

taint elemental from heros of horror, pretty much as close to a evil elemental you will get, without getting into the elemental evils.
