Accepted, but feel free to think of more runes as you go, especially sense I like magic to have practical and peaceful purposes, and many of these are combat-oriented or can really only be used logically for combat.

May I suggest the rune-system from my favorite MMORPG, RuneScape? In it, there are only a handful of basic types, but they can be combined to create spells. An attack spell, for example, might cost 5 Fire Runes and 2 Air Runes.
But it's up to you.

Only rune system I'm accustomed with is the one that I mentioned, so the runes in such a combat oriented game are obviously rather combat oriented. I do intend to have them used at various points for other things.
