Teleportation chamber

This provides a couple advantages for class four and higher ships. First, it offers a room onboard your ship where it is possible to raise the dead and use transportation magic (except dimension door). Second, it permits you to use the goto ship spell to reach your vessel, and allows you to reach other vessels with teleportation chambers much more easily.

Note that these chambers are the vulnerable points of your ship, anyone with the spell goto ship can get onboard, so long as both the player and the ship are in the outerworld or in the same room. You better have a quicksilver golem with a defined friends list if you have this module.
