You become a master of all weapons associated with your armor. You deal 1d6 additional damage with any attack from a weapon that is part of your armor, including unarmed attacks using the hammer fist ability and weapons that have been attached to your armor as an armor upgrade. The additional damage is of the same type as the weapon’s normal type. Also, while wearing heavy or powered armor, you gain a +2 bonus to your KAC against combat maneuvers.

You can easily move past dangerous foes.

You can spend 24 hours of uninterrupted work to exchange all your drone or exocortex mods at any time, even if you haven’t gained a level. Any other drone features (such as its chassis or bonus feats) can still be exchanged only when you gain a level.
