So, I was reading the rules for spontaneous metamagic earlier, and I noticed that they mentioned that the required full round action for them is not the same as a 1 round casting time. I'd never heard that before, since most of my actual play experience with 3rd edition is PC game based, and I don't think anything I've played has made such a distinction. So, I went and read the rules on 1 round casting, and they are a lot different than I thought. Apparently it actually means you have to spend a full round action, and maintain the casting process while everyone takes their turn. Then the spell gets cast at the beginning of your next turn. So, the way ToEE implements it (which is a common mistake, I guess) is very generous. There aren't a whole lot of these spells in the core books; mostly summoning spells. But one immediately came to mind: People complain about Sleep dominating at early levels. But by the real rules, you can't just win initiative and knock the entire enemy party out. Even if the wizard acts first, everyone gets a chance to disrupt the spell being conspicuously cast at them. Also, this suddenly makes Color Spray look a lot better. Anyhow, I thought some people here might be interested in this tidbit. I'm kind of curious how much it'd affect strategies if it were actually implemented (it could easily be implemented by rewriting all the relevant spells, but it'd kind of be nice to not have to do that). P.S. it's not all bad for the player. Now the balor might not want to immediately try to pop in 2 hezrous, because he has to actually concentrate on it for a whole round while the PCs blast him.
