Go into the Forge then go to Foundry. Make sure that you are next to a completely flat wall. Place a Double Box Open up against the wall facing outwards. Edit the spawn time so that it does not spawn for 45 seconds. Start a new round. Go to the location where you placed the Double Box Open and spawn a Wraith directly on the "tear drop" of where the box spawns. Go into Normal mode, get in the Wraith, and wait. The box will eventually spawn and the Wraith will be jammed inside of it. Look all the way up and start shooting. You will not receive damage, but the Wraith will. However the Wraith cannot explode because you cannot kill yourself in this position. The Wraith will soon be totally destroyed. The best way to tell is if a Wraith is destroyed is when blue flames appear on the two front "wings". Note: This works about 90% of the time. Once you have seen the blue flames you can delete the box and see what it looks like.
Enjoy!
