Hello, Have you done any spells before? Or have any kind of magickal training? You would have to be a little more specific about the summing spells your looking for sence most would be written to summon only one entity or kind of entity. I don't think that there are any spells to do a general summoning but I don't need spells to summon things so I'm not totally sure about that. But I have a book I haven't read yet about summing spirits and other beings so I could get back to you on that.
