The question is quite simple - Death Knell can't be cast by sor/wiz but Death Knel Aura (both versions) can and cannot be cast by antipaladins - is it not strange? I think this is not consistent and should be changed. I think that antipalladins should be able to cast Death Knell (why not - they are antipalladins). And Wizard necromancers should be able to cast Death Knell Aura - they are necromancers. Witches can cast it and so should wizards too:)
