Assuming the spell works correctly (no idea) you would need to go to:
http://www.project1999.org/forums/showthread.php?t=2651 and download the eqchangesv3.zip file and extract those files.
It should have a spells_us.txt in it, this is what handles all the spells for the server.
However if you have done that, and it still doesn't work likely a spell not working correctly issue, but I have no idea never used it.
