The model gains Grind Attacks (X), and can make Grind Attacks as Supporting Attacks, ignoring the maximum number of Supporting Attacks. When the model is not Engaged in Combat, X is set to 1. At the start of each Round of Combat that the model's unit is fighting, except for the First Round of Combat, X is increased by 1 (e.g. Grind Attacks (1) becomes Grind Attacks (2)).
