Confusion

Play this tactic at the start of the battle, after both sides
have deployed but before the first round.
Choose a fighter from your opponent's starting
crew on the battlefield, and choose one Melee
weapon they are equipped with. For the duration
of this battle, when the fighter wishes to use that
weapon, they must pass an Int check. If the test is
failed, the fighter's WS is treated as 6+ for attacks
with that weapon this activation.
