How do you disable the use of certain preciousstones?
How do you change the item id of a precious stones (ie city protection from 57 to 57:3 so that 57 won't protect stuff but 57:3 will)
How do you create your own custom block (ie 57:3 does a 10x10x10 and 57:4 does a 15x15x15 protection)
How do you access the mysql database to do this stuff if need be, and how do I create one?
