The only character that can make this glitch work is a Barbarian. In edition, he must be at Level 71 or higher, have at least one skill in Leap, have 185 strength, and 87 dexterity. (The stat requirements have to be met before a weapon is put on.) If all the criteria is met, aquire a Flamebellow Balrog Blade (Unique) and put it on your Barbarian. Next, set Inferno on the left-click hot key which Flamebellow gives you. and set leap on the right-click hot key. Go out of town, use leap and while you are in the air, hold shift and left-click (Inferno). If you are sucessful, when you are attacked by a monster or another player, they can only get you down to 1 life (Invincible). You can tell if it worked by checking your gear, the backround will be red like when you use Whirlwind. WARNING: If you use this glitch, your Barbarian may only use Inferno as an attack, nothing else. Once you leave the game, your Barbarian will go back to normal. Also, if your opponent continuously trys to kill you, your gear may be damaged.
