All damage is categorized in to 8 damage types: laser, heat, physical, surgical, mining, energy, radiation and transference. Some ships have resistances or vulnerabilities to particular damage types. For instances, the serenity is particularly vulnerable to mining damage. Some times the player owned version of a ship and the AI controlled version of a ship have vastly different resists. One common example is the Pax. The AI Pax Astralogica is nearly immune to all damage but surgical while the player controlled version, the Pax Astronomica, has moderate resists to everything but mining damage. In addition to ship-Resistances, diffusers can offer additional protection. Also, some specialised base-kits have built in resists.
