Keywords
Area Damage
Area Damage X: A cumulative, triggered ability that means, "Whenever damage from this unit's attack causes a unit in this arena to be discarded, this unit may do X dice of damage to another unit in this arena."
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.
Meditate
Meditate: An isolated effect activated during a POP chance or your build step that means, "You may play this card from your discard pile without paying the printed cost. Play only during a POP chance or during your build step. When this card would be discarded, remove it from the game instead." Meditate can only be activated when the card is in your discard pile. Paying the Meditate activation cost means you don't pay the normal printed cost of the card.
Stun
Stun X: A cumulative ability triggered during the damage placement POP that means, "When this unit damages another unit, that unit gets –X power until end of battle." If no damage counters are placed as a result of damage, Stun doesn't occur. Stun works anytime the unit damages another unit, not just when it attacks. Only the unit with both Deflect and Stun abilities can stun when it activates its Deflect.
Redirect
Redirect: An activated ability that means, "If this unit is attacked, choose one of your other units that can be attacked and damaged in this arena. The attacking unit attacks the chosen unit instead." Precision will cut through Redirect just as it cuts through Intercept. However, there are cards that can cause a unit to lose Precision, or part of its game text.
