Do abilities that allow you to ignore a certain amount of hardness reduce the hardness by that amount? Or do they only ignore the hardness if the amount you ignore is greater than the object you are damaging?
For example, the Stonelord's stone strike ability ignores 2 hardness per level. If I am level one and strike a wooden door (hardness 5) can I use the ability to reduce the hardness by 2? Or does the ability do nothing to a wooden door until I am level 3 and can ignore 6 hardness?
