Modification Categories
There are five categories of modification. Each category has separate rules governing its use.
Engineering Systems
These modifications offer unique functionality to the ship. Each engineering system can be chosen multiple times.
Operation Systems
These specialized modifications aid in the operation and response of the ship. Each operation system can be chosen only once.
Suite Systems
Suite systems add additional functionality to the ship in the form of bays, stations and designated areas, offering increased utility to civilians, crewmembers, and troopers. Each suite system can be chosen no more than ten times. All suite systems require a ship of size Small or larger. In addition to their modification slot cost, ships are limited to the number of suite systems they can have, depending on the ship's size and constitution modifier, as shown below in the Starship Size Maximum Suites table.
Starship Size Maximum Suites
| Starship Size | Maximum Suites |
|---|---|
| Tiny | — |
| Small | -1 + con. mod. |
| Medium | 3 + con. mod. |
| Large | 3 + 2x con. mod. |
| Huge | 6 + 3x con. mod. |
| Gargantuan | 10 + 4x con. mod. |
Additionally, unless otherwise specified, each suite system can accommodate a standard number of civilians, crewmembers, or troopers, as shown below in the Starship Size Suite Capacity table. A ship does not gain a feature that accommodates less than 1.
Starship Size Suite Capacity
| Starship Size | Suite Capacity |
|---|---|
| Tiny | — |
| Small | 1 |
| Medium | 4 |
| Large | 400 |
| Huge | 4,000 |

Universal Systems
These modifications offer passive benefits to the ship as a whole. Each Universal System can be chosen only once.
Weapon Systems
These modifications deal with the installation and improvement of weapon systems. Each weapon system can be chosen multiple times.
A ship is proficiently equipped by having the weapon system installed, therefore any crewmember using a system can add their proficiency bonus when the weapon system indicates.
