It happend again *angry*I was forced to combine 3 Fire gems, I was not able to combine any other gems after that.I would have chosen the III and IV Level Earth gems instead.
I am annoyed by this as well. It is nice that the AI can't do it either, but it still sucks. I wasted like two of those piercing shots, where it only takes out the two gems instead of all of the gems of that color.
