How do I call on Duke Sallos?
How do I prepare the room i.e. do I need certain candles and incense? I’ve heard it’s red candles and Sandalwood incense, is that right?
What does he like in return for his help e.g. food? drink?
I will draw the sigil and chant his enn but what else do I have to do and how will I know if he is there or has answered me?
