Account Lock System - Lock your account with Master Key - an secondary password of your account for extra security
Type command in-game:
- Lock system blocks the following: item move, char delete, post, pk clear, duel, guild, stats, reset, item sell, personal store.
- You must replace 0123456789 with your own password with length of 10 letters or numbers!
- This way you could let your little brother play with your account just for level but not do anything else on it so you don't suffer later. :D
