Keywords
Critical Hit
Critical Hit X: A cumulative ability triggered during the pending damage POP that means, "If you rolled at least one natural six with this unit's attack dice, this unit does X more damage for this attack." Only one natural "6" counts in the attack roll after re-rolls. If a unit gets the Critical Hit ability after you roll attack dice, it's too late to affect the damage. Accuracy can't increase the die roll to a natural "6". However, you or your opponent may use an effect to re-roll dice to affect the number of natural sixes. (You only count the six, if any, from the roll used for the attack.) Critical Hit applies only to dice rolled for an attack, not to dice rolls for abilities like Retaliate.
Equip
Equip: A selective effect on Equipment activated during the build step that means, "Attach this Equipment to a unit. Play only during your build step." You can pay the Equip cost only once per turn.
Riposte
Riposte X: A cumulative ability triggered by the roll of a natural two during an attack that means, "If the attacking unit rolled at least one natural two against this unit, this unit does X damage to it when the attack ends." Only one natural "2" is counted from the attack roll after re-rolls. Negative Accuracy can't decrease the die roll to a natural "2". However, you or your opponent may use an effect to re-roll dice to affect the number of natural twos. (You only count the 2, if any, from the roll used for the attack.) Riposte applies only to dice rolled for an attack, not to dice rolls for abilities like Retaliate.
