... they have buffed with Life's Grace, a Death Ward-like spell that also protects against ability damage/drain from undead attacks ...

I did a search for the aforementioned Life's Grace spell and could not find it.Can someone tell me in which book it can be found, please? Or is it 3PP or something from 3.x?
Follow-up on this question (since the 1-hour editing window has long since passed): I found the spell finally.
Life's Grace is in the Spell Compendium (a 3.5 sourcebook), which explains why I couldn't find it in my search of PF sources. :)
