A Errata do produto fornece alguns orientação:
Armor has damage reduction listed even when it also has hull points, because some weapons bypass armor defense, thus requiring a simulation of armor adding "extra health" and the ability to "reduce damage", all in one package.
Alan Bahr, o designer, diz que, embora não haja arma que atualmente contorne os Pontos de Hull, mas tenha como alvo o DR, eles se reservam o direito de adicionar uma arma desse tipo mais tarde, então eles queriam estabelecer o que aconteceria nesse caso.
The intent here is this:
Hull Points block all damage.
Eventually we might release a weapon quality that "ignores Hull Points", but we still want Armor Reduction to apply. In order to accomplish that, we preemptively included this text.As of now, there are no rules that Ignore HP awhile allowing Armor Reduction to apply. It's all or nothing.
If your Armor has HP, you can't be hurt until a weapon does 1 HP worth of damage. Once that happens, your armor is trashed and you get no benefit from it. Armor Reduction doesn't apply.
