Thanks to the Ablative armor an energy Beam is scattered and therefore its' force and effect are reduced. Unfortunately not every spaceship can be equipped with this, because the construction of ablative armor plates is very complicated.
In BOTE 10% of the damage goes to the ship's hull regardless of how large it's shield is. Ablative armor neutralizes this damage, but unlike Hull polarization it applies only to the Beam damage, while hull polarization applies both to Beams and Torpedoes.
