Looking for a way to increase PK protection past lvl 30

Hi there,

i'm looking for a way to increase the PK protection past lvl 30
i did already search the forum before posting and there are several references about this BUT they do not work

the most common idea i come over was this: Perfect world v70 release 1.46 - Page 10 - RaGEZONE - MMO development community
doesn't work on my 1.5.0 ...maybe it was working on 1.4.6

if anyone has an working way to increase the PK protection past lvl 30 let me know, willing to pay for a good "fix"

my server has pvp enabled, and it will remain that way, i just want to provide an extended protection to my players so they are not PK by high level while they quest/level up

my server version its 1.5.0, i got it from here: https://forum.ragezone.com/f754/perf...5-1-a-1045161/

please PM me here in forum if you have any fix

thank you
