I've been trying to figure out a 'major magic' system for Pattern/Logrus users but have not been successful.
In the various books, they use Vancian Magic (https://en.wiktionary.org/wiki/Vancian_magic) which I fucking despise. Plus, it's not realistic that anyone would spend an hour or two every day or two prepping a spell.
Hell, most people don't work out half an hour or more every day despite the fact they know it would make them healthier. People are not realistically going to spend hours prepping spells. And also, I don't want them spending IG hours prepping spells.
So I'm at a loss for now.
Eventually, I might make some big confusing fucked up bubble map of various types of spells that work a lot like Pattern/Trump/Logrus/Shapeshifting where you can do stuff once a day unless you pick up the 'do second time in a day' or something. Not sure on that, we'll see.
If anyone has different ideas (other than "Why not let us use the minor magics as major magics" - put that under 'let's not') drop them here - maybe something will click.
Until and unless something is come up with, magics will be an NPC thing. The PC's will just have to content themselves with attempting to learn the 400-500 different major powers already in the game in the form of Pattern/Trump/Logrus/Shapeshifting.
In the books those that could use the greater magic did not prep spells every day. Once a spell was prepped it stayed prepped until used for utility spells and some of the more fancy one off combat spells. I don't recall Merlin having a combat spell that was just fireballs or whatever. The only time people seemed to throw magic around in combat that was not some sort of fancy one off combat spell was when they had access to some sort of source of power to draw on.
The light that burns twice as bright burns half as long. And you have burned so very very brightly......
What I'm working on now is something akin to the old 'power words' but I'm also thinking that this stuff would work for making items as well. Not 'hey I'm churning out magic items yo' but the various artifacts the PC's can work on (one per major power).
