Well,
i found this out by an accident and this is really non-sense and useless, just a bug on the game.
1.) Get any "Dimensional Ripper". You can build it as an engineer.
2.) Go to a vendor, open his menu. Equip the Ripper and cast it.
3.) While it casts (any time) put the trinket in your inventory, the cast should not abort.
4.) If the cast almost hit the end (calculate lag within), sell the item on the vendor.
Result:
If done correctly, you sold the Dimensional Ripper and you will get ported. The bug on that all is, that you can't buy back the ripper, you not even got the money from the vendor. You need to ask a GM if he can restore the ripper, if you want it back. My target was to not enable the cooldown of the ripper (which is 4 hours), but when i got the item back from the GM, there was a cooldown.
