Tractor

Tractor beams are very useful and can help capture ships and tow people. You can train tractoring to level one in warp one and above, but to train it to level 2 or more you need to go into empathy field. You can only get into empathy field when you engine is unequiped. You can have a friend tractor you to the wormhole or you can biuld a secret cache on the wormhole or you can send a slave into empathy field (slaves can go in and out with an engine) and hitch a lift on the slave with a tractor beam.
