[AreaOfEffect]

Its armor negating and starts with 1 point of damage, but every damage roll gets a DMR minus another DMR. In some cases, units got hit but didn't take damage because the second roll was higher, but in just as many other cases the rolls swung the other way and you took the damage difference plus 1. Since the rolls are open ended, that could amount to a lot of damage for those who rolled poorly. Due to the nature of the game mechanics, the average damage per unit hit is actually greater then 1. That is mostly because units that roll really well on defense are no better then units who just barely avoided taking damage.
