Armor

Armor protects you from being hit. Every time it does so, the armor is weakened and will eventually be destroyed; but the shield is targeted first and thus more vulnerable to destruction.

The lower your AC, the better. Very good AC will go into the negatives.

Armor can be repaired with various small tech devices.

* This is the maximum number of "damaging" hits a particular kind of armor can sustain in its pristine condition.
