Sorry, but I don't currently play GW2 atm... and the address I had before has probably long since been patched, or changed by updates.
The way I found the address, I believe... it's been awhile, is I searched for Float value when on a really high object, then went to a lower spot then I was and searched for Changed Value. Just keep doing that, and you should see values that go up and down when you go from a high point, to a low point. Then I think I just froze one of the values, or changed it to something low, and then attacked a monster, and it couldn't hit me because it thought I was under the ground or something.
