In the unlikely event that there are people out there who would like to fix the Necro, Bard, Druid and Cleric epic particles for themselves, I made a "one-click" fixer tool:
download link. Source is
here.
Drop it into your EQ folder and run it.
It makes a backup of the file that gets edited before it does anything, in case you want to undo the changes (the backup is "gequip.zae", rename it to "gequip.s3d" (replacing the existing one) to revert).
edit: may need to download and run vcredist_x86.exe from Microsoft
here if you get "missing DLL" errors.
