I've come up with an idea for spell casting in modern times. It's for a d20 Modern fantasy setting I'm doing. Spell casting is a skill. A class or cross-class skill depending on the character class in question. With the skill limited only to certain classes. No fighter's with Fireballin other words.
Each spell has a base DC to cast. This is equal to:
10 + Spell DC modifier
Low level spells have a low DC modifier. Zero level spells could even have a negative modifier (-2 for Detect Magicfor example).
Taking extra time to cast would help. As would certain feats.
But, this is something one person really can't do on his own. So I ask for your assistance. Advice and so on and so forth.
If you have any ideas on how to make this work, post 'em.
BTW, Arcane and Divine spells have separate skills. They are, respectively, Dweomercræfting(Int.) and Priestcræfting(Wis.) Three ranks in Dweomercraftingmeans the caster has a +3 when casting an arcane spell for instance.
I'm also thinking of giving each spell a cost in Subdual Damage. For example, casting a Detect Magicwould inflict 1 point of Subdual Damage whether or not the attempt succeeded. So if your first level wizard had a Con of 5 or less, it would be a good idea to have an assistant ready to catch him every time he is called upon to cast a spell.
Feedback and suggestions are welcome. I look forward to them.
