Does armor reduce the damage from each attack or the total damage a model takes in a turn?
ex. My metal gamin was hit by a fire gamin's spit magma attack for 2 damage. The FG hit his trigger causing a Burning +1 on the MG. Metal Gamin have armor +2 so that cancel's out the 2 damage from the attack. Then in the upkeep phase the MG will take 1 damage from burning. Is that canceled out by armor, or has armor already been used up for the turn? Similarly, if the MG was damaged by a second model in the same turn, does armor come into play again, or has it already been "used" that turn?
