Shush you~
That's just me telling you know so if something happens later I can say 'I told you not too, now time for your flogging ;P'

Alright, so if I'm reading your explanation correctly, it's sort of a more...shall we say magic designed to be used in ambushes and traps more? As in, he sets up a ritual/magic circles designed to make a spell more powerful? While that is a neat idea...it's not exactly something you would be able to use in a direct fight all that much. 

Considering most of the fights are going to be at close to mid range, he's not going to have a whole lot of set-up time. And by the time he would be able to set up, the fight might very well have already been taken care of by the melee or other more direct characters. Chances are, even, our characters are going to be the ones getting the ambushing happen to them.

Plus, with these 'ingredients' of his he needs to have perform these rituals sometimes...that would make it even more...well, shall we say somewhat useless considering once he's out, he's going to be out for good unless he can just suddenly pick up the required materials from a cavern floor.

While I'm not trying to discount this magic, I think it might be better to chose something that would be a bit more viable, otherwise I don't think this magic isn't going to really be used all that often, and more or less be useless. At its best, it could be much too versatile, at its worst, it's completely useless.
