Since we're on the topic of parry How do you handle it when two models go up against each other and one has the parry ability, and the other has the parry ability, and parry on his weapon? (Neither have smasher)
1) one parry each cancel each other out, so model B forces only one reroll on model A.
2) all parrys go off and model A rerolls his two highest dice and Model B rerolls hes highest
