Greetings,
I'm currently playing a summoner, with access to control, soon master type IV on Planar Summoning list, and I wanted to get some input as to how to determine your knowledge of what you can summon.
Now I'm playing in a setting where summoning of extra-planar creatures is rare due to the setting condition. That leaves me with a focused use of the list on Elementals.
We play with all the books, F&I included, and I had no trouble summoning "standard" elementals, but my GM has trouble with the thought that I could summon "hybrid" elementals, such as Elemental serpents, and "lesser elemental riding drakes" (the type IV that I could technically now summon).
Now xeno-elemental skill apart (I don't need to be a specialist on elemental behaviour and habitat, individual names, etc...), what type of knowledge should I consider granted through the knowledge of magic and it's possibilities should I consider to be innate, and what should be acquired through other means?.
I am asking the question so I can know how to manage my expectations, when my GM isn't the best at communication on certain things.
This is also valid for any other summoner who wants to manage his expectations as well. Though I would advise to have demon lore when summoning demons vs elementals (seen as complicated vs simple beings in my view)
regards
