Alright, so you have 130+ items on your server and you do not want people to be able to use WeaponMaster do upgrade to that gear.
Here's an easy fix:
In NPCDialog.cs go to Market High Upgrade or whatever you called it in your source and below
Code:
if (GC.MyChar.Level >= NewLevel)
add this
Code:
if (NewLevel != 0 && NewLevel <= 130 && PrevLevel < 135)
This makes it so he will not up any gear above level 130 and you can make your specialty items as a quest or what ever. This also fixes it so people don't get the wrong items if you have job specific items on your server.
EDIT: Sorry this is for 5165...
