Why is the game lagging so much all of a sudden? I need to click 5 times before an item is finally sold to NPC and when I'm fighting a boss I need to wait 2 seconds each time before a skill is finally used, meaning I can't form links to stun and knock-down the boss. I already lost 10% exp on Lv.70 because I couldn't drink my potion in time...

Do you have any other programs open when playing Eden? That could contribute to it.

Does it happen on all channels, or only a certain one?

As jellyfish said make sure there is nothing else running in the background while you are playing or else it can cause your game to lag also try a different channel because maybe the channel has to much people for your computer.
