COOP, great questions!
I know when I started my local, I had designed everything, but the Ritual.
It was funny, but my coat of arms had:
Clasped hands, and open book, a lamp, the rising sun, and crossed swords!
These are many symbols that are used Nationally.
Ritual, get a skull, coffin, lamp, etc!
According to The Funky XO site, that is what they used so why not take them also!
It depends on what your Group Beleives in and wants to profess to your possible new Associates!
Round your Ritual around that!
Hazing Right, dont!
