When you run a secret mission, you have to choose which TF to use.
However you can only select one TF unless you unlock an additional slot.
You can unlock the second slot by spending 200 gems. (I have no idea how much it would cost to unlock the third slot, but I’m guessing it would probably be more).
If you go into the secret missions, you’ll know what I mean.
So what I’m trying to find out is whether spending 200 gems to unlock that second TF slot will unlock the slot forever, or if you need to unlock it again every time you do another secret mission?
