Killing Players with legit spell Disallowed?

4 people died to me. Apparently 2 were Gms.

Well anyway.... This has taught me a lesson, Dont fucking kill Idiot GMs with spells they dont understand. Read the fucking combat log. Its called Demonic Sacrafice, A spell DESIGNED AND IMPLIMENTED by blizard.

If the spell was not supposed to be used, there would be a rule against it or it would have been removed from the server.

I DONT HACK. I just outsmart. Of course, if those GMs are also Moderators on this board, there's no point cause they'll erase this and put up something asinine.
