There is actually a gold hack... but its hard to get it working if you can stop the LoL Anti-cheat and from it crashing you. other then that you can just change your values or some how spoof the LoL Value Updater to say you have more gold so it gives you more instantly.
Also ive seen HP Freeze's from good packet editors and they laughed each time i played them.
Also... Lvl30 PvP bots that play games for you using Auto Click-It.
