I have the "Order and Chaos" weapon. It is supposed to do damage to the bottom 2 enemy cards. If they are dragons it does double damage.
The issue happens if the first strike of the weapon kills the bottom card...instead of the 2nd hit going to the 3rd slot enemy, it jumps up to the 2nd slot enemy. I am not sure what would happen if there wasn't an enemy in the 2nd (or 1st) slot....but I do know the weapon behavior is broken and doesn't behave as it should when you deal the killing blow to the bottom enemy.
