Drachasor, could you give me citation for increasing, or adding to a thaumaturgical spell's duration, outside of the original casting, because I'm honestly not able to find it at the moment... Second, I actually had an idea along those lines for limiting it and gave it in another thread.. It does get to a pretty crazy point, and I was thinking that it'd probably get harder and harder to place spells on someone, the more there are. So maybe an increase in complexity for every spell already on the target? So, if someone wanted to place 4 aspects on themselves, and cast it in a single spell, they'd have no increase in complexity. But if they, by chance, cast it cheaply, putting one spell on top of another, and another, I'd think that maybe it would increase by 1 or 2 for every spell already on. Or something possibly a lot more complicated, increasing the complexity of a spell going on the person by a percentage of the combined complexity of all the spells on them currently. At that point though, you start getting a bigger headache as well ;P
sinker, i know... which is what is rubbing me a little raw... >.< Its like trying to get all the best benefits, cherry picking from different sections of the rules for the best results, and I don't like that...
