Pierce tells you the minimum amount of damage a character can do in an attack, although a character can never do more damage than its attack total. For example, say a character with Pierce 2 attacks. After flipping battle cards, the attack total is 5 and the defense total is 4. Normally, the character with Pierce would do only 1 damage, but because of Pierce, it does 2 damage instead. This also works if the attack total is equal to or less than the defense total. Say the attacker has an attack total of 5, but this time it runs into a massive defense total of 9. If that character had Pierce 2, it would still do 2 damage. If the character with Pierce 2 had an attack total of only 1, it would do 1 damage against any defense total.
Yes. For example, say a character with Pierce 4 attacks Insecticon Skrapnel in bot mode. (He has the ability "This can't take more than 3 attack damage from a single attack.") After battle cards are flipped, the attacking character would do 2 damage, but Pierce raises that to 4. Insecticon Skrapnel’s ability would then reduce the damage done to 3.
6. Pierce is a minimum damage.
After flipping the three orange, she has Pierce 4, meaning she would do a minimum of 4 damage.
In this scenario, Arcee deals 1 damage.
Pierce stacks, so it would be 6.
Thats correct. In this scenario you would be attacking for 4 with Pierce 6. Pierce stacks on Pierce, but not on regular attack damage.
Yes. Bold, Tough, Pierce, and other key words with numerical values do stack.
Pierce is an ability that applies to attack damage. But, effects like Insecticon Skrapnels or the Safeguard ability will still apply. In your example, Skrapnel would take only 3 damage.
As stated, the enemy still has Pierce so Jazz's alt mode ability does not trigger.
