dragoner said:iirc something somewhere about "jump weapons" that stated certain effects, it seemed due to mass reflection, and how the ancients destroyed planets. However, if the GM has already just gone with the misjump, rather than telling the players that your ship will instantly be destroyed, then they should go with what is done and keep rolling.
That's different than jump drives. In all Trav versions it is just a misjump chance for being <10 diameters.
