@Human to be fair if he were to use four Skeleton Kings they wouldn't be as strongnas the one using up 4k regular Skeletons with over a million of each stat. But the four with 1k regular Skeletons would still be OP.
@Victor Reyes if i were the mc id make at least 50-100 skeleton kings and the rest can be the berserkers, archers and mages, in total he can have almost 5000 skeletons, at least 100 kings 2000 berserkers 1000 archers and 1000 mages or he could choose to format it in a different way, and i didnt see anything about a limit to skeleton kings
