I agree with Zakath. The gods have obviously made the ritual convergable so that it can be used as such.
Now, how sporting you are will dictate how you use the ritual. I, for one, will not use armageddon on anyone who is not very close to, or larger than me in size.
Anyone else, it makes sense. I'm not giving up my god given talents in order to make myself a target.
