    [Share]Anti-Pk Protection for low level characters
    « on: December 09, 2010, 06:28:36 AM »

    The patch wasn't created by me!! I haven't tested it! I just share it!
    The patch covers two features:

    It protects low lvls from being PK'd by high lvls.

    Admin can specify the difference of the lvls. Then if difference of attacker lvl and target lvl is more than the specified difference, the target is protected only if all of the following is true:

        * target is not PK
        * target is not flagged (chaotic state)
        * target is not member of a clan that has mutual war with attacker's clan
        * target is not in PVP or SIEGE zone


    I tested the patch and it works both for physical skills and magic skills.

    It protects players from mass PK.

    Admin can set limit for number of PKs within certain time and punishment if the limit is exceeded. Currently only jail punishment is supported.
