So this is something that people have been using with eHex since he came out, see it recommended all the time. Model A kills a guy, creates a Black Spot attack which contributes to Model Bs shot. If that kills, Model B gets a BS shot, and the waterfall continues.
Problem is, the wording for Black Spot states "immediately after the attack is resolved it can make one additional melee or ranged attack". So if you have to take the shot immediately, you cant declare another model as leading the attack, as then you have skipped the BS shot and moved to the next models combat action.
Has everyone been playing this wrong? Am I right in thinking it cant actually work?
