Find this line in your map/status.c then add the statuses that are made by Tarot, if im not mistaken they are also included there and tagged under 'SC_'
//Status that are blocked by Golden Thief Bug card or Wand of Hermod
Might wanna check for newer revisions of your SVN, I am really sure that you don't need to have a script because the function was already built in.. I had an old rAthena version which was like 13xxxx something but the behavior of item_noequip for me is that you can still equip the items but it wont have any effect, which is fine but different from the eAthena version.

A clue..
Try browsing the item_db related to "sc_start" and reading the item_bonus.txt
http://eathena-project.googlecode.com/svn/trunk/doc/item_bonus.txt
They were supposed to be expanded classes that were dropped by kRO..

Actually, that's not an error, that only occurs because as the way you've started the script, it does not define a map and would work fine as long as every variable that it calls, etc. would always be attached.
UPDATE `ragnarok`.`mob_skill_db` SET `CONDITION`='longrangeattacked' WHERE `CONDITION`='longrangedattack'
don't forget to backup because i just wrote that code from scratch
To know if the item script really works, you might want to enable this in your player.conf file. As Kido said, you should try increasing the % rate to test it further..
// Display the drained hp/sp values from normal attacks? (Ie: Hunter Fly card)
show_hp_sp_drain: no
Well there could be a lot of reasons behind that. But first, we should diagnose the problem. Did they invest on their castle? And secondly, did you manage to restart the server or reload all the server script via @reloadscript? If this is a case then they should wait for another 12 hours from the time the server/script reloaded before they can get a treasure box
