I love the theme, not gonna lie. And not gonna lie, this needs some polishing considering the notation. What concerns me the most, is the "Part of the core" rule, which states: "Whenever a player unit takes a wound roll one die and apply the effect...", then the table below states that on 1-5 you remove a model from that unit. How do this applies to models with Tough(X)? Tough(X) states that such model needs to take multiple wounds to be killed. And the table as is, implies that it's a one-hit-kill.
