I'm curious to know if the effect of Weaken would counteract that of Cunning. I don't think that it would. The way I read Cunning is that as soon when you roll and evade you also add a block result. After those results are added, Weaken cancels an evade. It doesn't seem like the two results should be linked after they have been added.
Am I correct about how the two interact? Or does Weaken keep Cunning from providing a block on the first evade that gets rolled?
