Following your logic to the letter...
I, Orinoko, Finbar and Neidhart issue challenge to you, You will fight us 4 on 1 and you not be allowed to use rituals. If you do not accept this challenge I brand you a coward for refusing.
Whether the terms of this challenge are deemed fair or not by you or anyone else really serves no consquence to me.
