Chain Axe upgrade - this is a function only as the cost is shown when the CCW changes to chain axes, I've removed the zero from the end to make it a bit clearer.
Free champion - when you select the aspiring champion with unit size set to 8 it shows aspiring champion (free) at a cost of 19 and 5 (chaos marine and mark), it is only the cost of the upgrade that is free, you still have to pay the points for the marine and the mark
