Definitely -- thanks! I'm pulling spells from R&RII because they've got lots of spells with the flavor I'm looking for (elemental-earth-related). I'm probably going to be toning a lot of them down a little or a lot, in order to mollify my DM -- earthblast, for example, is mostly more powerful than fireball, which just ain't right. (comparable damage, larger AoE, cool effect on anyone between caster and AoE, nifty nasty side effect on anyone within AoE -- all in exchange for limited location in which it can be used, and a smaller range. We'll be altering its damage way down to compensate).
