Sorcery for Mass Combat

Sorry if this is a noobish question, but...

Have any of the released rules (or forum contributions) delved into the subject of sorcery for mass combat scenarios?

I am increasingly interested in mass combat with Conan rules, and have had to use other mass combat books by other publishers like Fields of Blood or Cry Havoc or Heroes of Battle.

To give an example, I was trying to cook up the game stat info for something along the lines of mass greater ill-fortune.

Any ideas?
Go to the Conan page and download the pdf rules for Mass Combat (or use this hyperlink: Magical Attacks are listed beginning on page 8 of the pdf.

I also remember there being info on sorcerous units in The Free Companies supplement. Hope this helps. 8)
