I was on TC1 playing with drake builds ( I'm still kinda fixated, but at least I wised up and started doing this on the tc). Anyway I was hoping to put venomous bite on a crimson, but found that to be impossible. I had trained poison first, hoping to unlock it. Now am I correct in assuming that the reason I couldn't train it is that the drakes already have dragon breath, and they are both special abilities? I thought you could swap those out too, but apparently its only magic you can do that with?
