All my pups hold the superstition that saying a god's name will lend power to that god. Even Amascut does. I don't know if it has basis in fact. It maybe be an attention = power thing, but Amascut as usual is always the spanner thrown into the works since she actively avoids attention by pretending to be someone else.

It's kind of hard to hold to in twitter RP because it makes things awkward, in case you pay attention to Amascut's activities on twitter.

I don't know about any of their specific superstitions though.

As for myself, nah. I am Roman Catholic though so that may count for something. I nom on God like a good zombie every week, but people have noted I don't cross myself going past graveyards or churches, I don't say grace before meals, abortion and homosexuality doesn't make me froth at the mouth, etc. Meh. Thank goodness a left leaning Jesuit is Pope now. Ahahaha.
