That's so simple that does not even need Screen shots.( This is my first topic so don't get it wrong if I do something wrong)
So lets do it.
1. Open your Phx (I use 3.5) then log on your lineage char.
2. Stop the global actions and get just your logs
3.Get Stones and the item you wanna then use one stone.
4. Go to the PHx and Copy/paste the Packets for "Item Use" and "enchantitem"
5.Set the timer to 0.10 then click on the timer.
6.Now your item is fully elemented :)
