I think ths is definitely a much better step in the right direction. The way the reagants are managed is much simpler and easier to work around, and don't have the inherent problem of adding boring stat buffs that scale infinitely. I personally would have made the reagant abiity work similar to TF's Pick a Card, so that I can put it on a basic ability and leave the ultimate slot open for something more powerful. However, your route does make it easier to quickly swap out a reagant in reaction to something.

The only thing I would recommend further is to find some common theme for each of the reagants - like Sulpur generally increases damage, Salt increases his defensive capabilities, etc - that way it's more intuitive which reagants should be used for a given situation. It also helps enemies understand what weaknesses they should target to counterplay the reagant effects. You aren't far off with what you have already, there is just a few deviancies from this idea (Salt seems to be mostly defence, but randomly adds resistance shred).
