prestige class with nonlethal resistance?

[Venger]

I seem to remember a prestige class that had damage reduction that I believe only applied against nonlethal damage. I think it was larger than normal DR as well (like 15 or 20 or something) so it would apply more often.

does anyone know what class this is?

Only two classes are coming to mind for me, bone knight (i think) for clerics.

And warforged juaggeenaut, for warforged of course.

Crimson Scourge from Cityscape gets out right IMMUNITY to non-lethal.

I believe Kord's prestige class also gets resistance to non-lethal. I forget what it's called.
