Hi Codo! Thank you so much for taking the time to comment, your interest in my faction is a massive compliment in and of itself! 🙂
I understand your concerns over balance, it is indeed powerful to be able to capture a piece by moving into a clearing. But in the early game, Wolves don't have enough actions (Vehemence) for this to be overly oppressive, and in the late game their militancy is still not as brutal as a Warlord with 4 prowess. Moreover, the Wolves are forced to direct most of their attacking to the opposite Wolf Pack (for both scoring and action engine building), so they don't want to be using their actions on other factions too much!
Vehemence = no. of Captured Bishops + Knights + (Queens x2). You can just count them up on your board.
Wolves have a supply of removed warriors like any other faction, but these warriors can't be redeployed. Hence maintaining a strong board presence is very important for them! This obviously contradicts their checkmate scoring condition, making it very difficult to know how much to sacrifice to force checkmate or a promotion! Only Wolves can capture pieces.
Yes, both factions have separate hands and crafted items/improvements. It wouldn't make any sense thematically for arch-enemies to share resources like that 😁
Hopefully this has answered your questions, if anything is still unclear then don't hesitate to shoot me another reply! Thanks for your enthusiasm for this idea, it makes me happy!
