You need to run the SQL file than add the LUA script inside your LUA_scripts folder.
The table can be found in world database under the name 'z_leveling script'
You could give multiple items by seperating them with comma (,) remember that you also need to add counts and the comma too exp :
item = '4824,4306,4338'
count = '1,100,100'
that means 4338 x 100
