I just found this because it came up first when sorting turn-based games by “new & popular” yesterday. So far I haven’t got around to making my own games.
You literally guessed the exact mechanic.
Well, the ring of fortitude explained that one to me. While I have peeked at the source files, that’s not necessary to figure these things out. Thanks for explaining the stats!
Maybe it is connected to reapers somehow?
Maybe it’s useful to give more context: I had a lot of archers and one assassins, the Reapers died first and without causing causalities, and the only unit that got causalities in that fight was my merc. cavalry. Edit: Actually, I’m not quite sure whether the Reapers caused those causalities.
