Does anyone have any decent rules for improvised or freeform spellcasting in D&D 3e/3.5e and/or D20?
I kind of want to break away from the set spells for a while, let the players create their own.
I'm trying to come up with a system of my own, using some ideas from other systems (GURPS has rules for this concept, and I found some online for HERO as well), but in trying to get it into D20/D&D may be tough without hampering the character too much.
Any ideas are welcome.
