Well, I'm actually considering detailing a few exploits to clear up the interp. issues, since I know that 'change technology' is...kind of a broad power, as is 'is craaaaaaaazy smart', as well as maybe providing a few examples of the Servants he can animate and one God to give an idea of what he can do. For example, here's something that stands out in my mind as something he could pull off...
A) Going Viral: In an act of rebellion and an attempt to make a better world, he created a Super Serum over a few months (the old-fashioned way, no techno-engineering here), then synthesized it into an artificial retrovirus, planting discreet packets of it across several major cities of the world while out fighting threats, then set them to release and called up his colleagues to convince him *not* to do so. They weren't persuasive enough at that moment so he released the retrovirus, but they convinced him down the line, and he managed to engineer a neutralizing airborn agent for it over the course of two weeks, before the retrovirus could develop enough to enter its active stage.
That sort of thing is the stuff I'm thinking about adding. Think it's a good idea to go for it Wang?
