Looking in some of the grimoires, I have noticed that a lot of the materials that are needed are quite...out there and hard to come by. For example, lion skin belt? What is that? lol. I usually prefer to make all of my stuff (I recently made a quite nifty armadel with some candle wax, it turned out great. I still have to do the carving though, although I might just use a permanent marker)...some of the stuff, I cannot make. I usually improvise. Do you think it will take some of the effect of the invocation away or disrupt the ritual? I try to keep it as close as possible.
