Transposition
A transposition module disperses magitech beacons attuned to its starship, enabling the ship to teleport short distances. Transposition modules typically have the mine special property and are thus mounted on the aft quadrant and disperse inanimate warp pucks in one or more hexes. However, unlike most mines, a warp puck doesn’t harm nearby starships. Instead, the launching starship’s science officer can try to teleport the starship into the puck’s hex using the recall beacon crew action. After the science officer performs this action, that warp puck is destroyed.
The maximum distance a starship can teleport by activating a warp puck depends on the starship’s size category (for this calculation, Supercolossal = 0, Colossal = 1, Gargantuan = 2, Huge = 3, etc.). A ship cannot teleport farther than a number of hexes equal to the starship’s size category multiplied by the value listed with the module’s special property.
