**Updated to Buffet 18.104.22.168-Beta**
As per my comments against the full mod - this is my patched version of Buffet (buffet.lua and config.lua ONLY - you need the full mod to use this).
I've added a 3rd macro "AutoST" (for STones) which will show Mana Gems over Healthstones (holding SHIFT will force Healthstones to show).
I've also modified all macros so that holding ALT will switch to 'Conjure' mode (Highest-Rank Food/Water/ManaGems for Mages - Healthstones for Warlocks)
IMPORTANT NOTE: If you use this patch PLEASE don't yell at Tekkub if it doesn't work - yell at ME instead - ok?
Have fun with it
