There’s a typo in the Unit Builder and example. The example shows a stat of 9 being worth -1 CP, but the table lists a 9 as being worth -2 CP.
This is a small rules nitpick, but I realized that if the CP total isn’t a multiple of 4 then you might and well increase Guard by 1-3 because the unit cost will be the same.
Otherwise, I’m really into this game! I love the rules for Into the Odd games and it’s awesome to have a wargaming supplement. I would totally use this as part of a campaign.
