Free Archlord Exploit: Portal Exploit for Orc Berserkers

When you are a Orc Besercer you are able to get behind the Portals at some Dungeons. So you are able to deal Damage without using Potions or getting any Damage. Here is the Clue:

You have to buy some Speedup Potions and buying the "Storm Attack" Skills. Now you will try to "PK" some player who is in front of the Portal. When you attack him he has to leave the game, but still keep on running. So you are able to get behind the Portals. Perhaps you need some tries because it is not easy to get there. But after some time you will.
