So... I really like her theme and concept (she fulfills the 'alchemist' fantasy better than Singed). I also really like that her reagents (a design element which could've went in so many different directions!) are Salt, Sulfur, and Mercury (although my word-senses are screaming to make her Mercury into Silver, so that we have the alliterative 'S' sound.)

I think the effects her reagents give to her abilities feel tacked-on. Don't get me wrong, I like the Invoker-esque gameplay, the idea of 'synthesizing' (in real time!) different ability effects, etc. But her basic abilities don't excite me on her own (they're pretty generic), and get most of their effects from her reagents (not a bad thing, but again, they feel tacked-on).

My own suggestion (driven by curiosity) would be to have her reagents be her resource. They could be color-coded and her resource bar could hold three. I do like the idea that she uses mana in order to synthesis her reagents though.

I do think you're headed in the right direction though, as Shigfugjum said. His suggestion of the 'pick-a-card' mechanic (or some variation of it) might be one worth exploring. I also agree that tying the reagents effects to a common theme for each would be a good thing.
