Even if FakeDeath works, mobs that started their swing at you before you hit the FD button will complete that swing, even if they have to catch up to where you are and then swing. This will make you pop-up, even if FD worked.
To see if FD worked, look to your row of buff icons on the top of the screen. IF you see a little death's head, FD is working. Don't move, even if you pop-up. If FD worked, you will also see your MP bar slowly going down, but this takes longer.
If a mob hits you twice after FD, it didn't work. как это вообще переводится, как я понял тут говорится если загорелся значок Fake Death в строке баффов то он работает, уменя он загорался но мобы всеровно били,но при этом я еще и встать не мог!!!
