Quick question for everyone:
Do you guys think the RP would be better would some form of elemental magic?
No. I think it should be split into Destruction magic and an overall broader telekinesis type thing, kind of like the Force.
Beyond that, other types that I think would be cool to have:
-Enhanting and construction of magical artifacts
-Some divine power to contrast Occultism. It needn't just include the stereotypical Light and smiting undead; it'd be cool it they could also have something unique and less cliché like holy incense and smoke magic
-Some form of nature magic/druidism
-Summoning elementals and spirits to host in your own body (temporarily or permanently) to grow more powerful and wise, at the expense of having inner turmoil and a fragmented mind that can take away one's control or sanity if they are unprepared.
That's just off the top of my head. I can also think of a ton of combinations, like Thaumaturgy (Alchemy + Occultism), Illusion (Alteration + Telepathy), etc.
