Skeleton Enhancement Cards
-Unlocks head slot for skeletons and gives you 4 new items to give them!
-Look for "Enhancement Card Printer" in crafting. Crafted cards go in the normal armor storage
-No research required to unlock!
My original idea for this was to have the eyes glow when using the respective cards, but I do not have the gumption to learn such things. Because some people might want to use other helmets for skeletons I am not excluding them in the FCS, though the cards exclude everything but skeletons.
