Another old one....
This system makes use of all the items that Cloud_BR made that had luck on them, assuming they are still around, and if they are not.... make your own.
Luck
Items that have luck attached to them increase chances of various things including but not restricted to (assuming you add on to the script):
Luck Lotto - Each character on login has the chance to win 10k gold once per day (you can edit the prize)
Lucky Drop - More luck = more chance of getting something extra on the body of your kill (prize pool should be edited to suit your needs)
Luck Enhanced Resource Gathering - Chance of double the ore from a node NEW
Luck affected crafting - add extra damage to weapons, extra AR to armor (most basic method included)
* Critical Hit & Evade removed
This script is basically just the framework behind a luck event, if you want it to do other things go ahead and add them (I'm not giving away everything that this script can, could be or was tied into)
