Unlike these guys who are trying to tell you how to eat crackers and drink alcohol
, I would direct you to the dominions 3 wiki page, but it appears as if that doesn't know either
so, as far as I know, yeah, you are supposed to eat crackers and drink wine, good luck finding someone who knows. maybe ask Mr.Dr.P or if you can look at the dom 3 spell DB, I know it doesn't work with Internet Exploerer though, but it will with firefox.
Here's the thread.
