tested it a little bit more and I am still disappointed.
It may slay Demons and Elementals but they get a chance to save at no penalty
Thus they make their saves at a roll of
Elder Earth Elemental: 2
Fire Elemental: 2
Gelugon: 2
Glabrezu: 2
Apocalyptic Boneguard: 2
Cornugon: 4

This leaves me with a small 5% chance of instant kill (15% for the Cornugon).
Now don't get me wrong, I think the Club is a very balanced weapon (reminds me of the Slayer in Ultima 8), I wouldn't want a "instant kill-no save" weapon but I don't think it's worth the worry or the praise it is given.

By the way. What do the saves (roll+bonus) have to match in order to be successful? At first I figured it should match my level but then I slayed a Cornugon with a total of 12 although I'm only lvl11. I know my way rather well around in the D&D 2nd Ed. but the 3rd still won't get into my head.
