Below is a zip file with both files sent by Stoner and Vespers' Eclipse of Harvestgain. His buffbot gives user options of being buffed with level 7 spells or level 8's. Thanks Stoner for this nice piece of work and now includes the most recent updates as of 09-16-2012.

Aug'd Foci Fix for CastAway
Right click on the CastAway.dll file and Save As to a folder of choice and then copy/paste/replace that dll inside the Castaway install folder (rename the old DLL for backup purposes)
