This method makes getting the Arena Grand Master trinket/achievements incredibly easy. The only catch is that you need to be a GNOME. Heres how I personally do it:
1)Die in the STV arena, near the chest.
2)Wait until a chest spawns (3, 6, 9, or 12oclock) and jump on top of it. Try to stand on the exact middle.
3)Wait until somebody loots the chest. At this point, you will be standing on thin air, as a ghost.
4)Wait until the next time the chest spawns but DO NOT MOVE. AT ALL. When the Arena goblin sets down the chest, people will begin to fight over it.
Simply rez and loot the chest, safely hidden inside of it. You can still be targetted, but they cant see you
Repeat this as many times as you want. It is especially good for getting AGM on twinks or other low level chars.
