The promotion from 0% to 5% costs 500 sparks.
The promotion from 5% to 10% costs 1,050 sparks.
It looks like the game will trap you inside the Barracks as long as you have sufficient sparks to spend on a promotion, so I had to use up all 1,500 of my sparks before it would let me return to the main map.
Not sure what this is going to do since I don’t really play the game anymore.
I used my sparks to promote the three Grimlocks since I’m most likely to use those guys in a Challenge.
