No, it isn't a problem that I need tips to fix. I need tips on running low magic. Specifically, casting classes.
I don't want to cut the spell casting classes entirely, but how should I change them? Maybe half spell slot progression for all of them? Is that too little?
Maybe put them all on the Warlock track, with only 1 of each level for the higher level spells?
These are just spit balling ideas for now, but what do you all think? How have you handled converting 5E to a more low magic style?
Edit: another possible issue, what do I do to keep the spell casters balance with the martial classes? I am thinking, maybe, of lowering general enemy saves, so it would not penalize a caster as much to also have some dex or strength.
