I may be wrong but ain't it working like this?
Run WPE PRO and select archlord as your base process.
Then scan for packet,after you've got it then send it as much times as you want which would basically mean spamming skill with no cooldown.
It was possible to dupe items via stall network and stall system + exchange using WPE PRO so who knows,maybe it will work with Archlord too but instead of item dupe - no cooldown hack.
BTW: Is it just me or I feel like this game is as ugly or even more uglier than Metin2 which is a complete failure?
