Hi!
Ivory Knife (https://ratemyserver.net/index.php?page=item_db&item_id=13039)'s description says that it applies status on yourself, which is incorrect. Status is applied on enemy according to script (tested it on RMS pre-re test server) and official descriptions:

Thanks for reporting, copied the description from renewal (which is using the same script) as replacement.
