So, a martial artist attacking with two melee weapons (or more, potentially, but for now just two) via the Sweep Maneuver.
You split the dice pool, naturally. You modify each attack appropriately. The first attack succeeds, knocking the target prone while inflicting damage per the Sweep Maneuver. What happens to the second attack?
Normally, this wouldn't be an issue, because the Corebook rules assume single-weapon melee attacks. After you'd successfully knocked then to the ground, your foe could either spend an action standing up again (allowing you to use Knockdown again), or they could stay prone, at which point you'd make a normal attack with your next action.
But attacking with two weapons kinda throws a spanner in the works, because you're making two attacks with the same action. How should this be handled? Once the first attack knocks the target down, does the second attack simply fizzle out, or not happen, simply because it no longer has a valid target? That would be awfully harsh. Maybe the second attack simply translates into a normal melee attack, instead of a Knockdown attack? That way you aren't being robbed of dice, damage, and half an allowed action.
But what if you're relying on Sweep to inflict Stun Damage instead of Physical? Say you're using a non-electric weapon, or that your stun baton has run out of charge. If the second attack becomes a normal damage dealing one, does it no longer deal Stun? Or maybe because both attacks were made as Sweep attacks, it still succeeds, and still deals damage as stun (assuming it connects), but it simply doesn't knock the target down because they're already prone?
I sure do know how to find the cracks in this rule system, eh?
