Emmisive Armor for Dummies, please...

[Baron Munchausen]

No matter which component is hit first, the emissive armor ability subtracts its level fromt he damage first. Then, the lowest damage armor tends to get destroyed first. Once you ae dealing with internal components the situation is reversed and the highest damage components tend to get hit first. These are not 'fixed' rules, though, so a clear prediction is not possible.
