Defending and mighty cleaving on weapons? I couldn't find a description in the excellent crafting spreadsheet.
Defending allows you to add the pluses of the weapon to your AC- not sure about Mighty Cleaving although I think it acts like Great Cleave for those that only have Cleave... There's a link on this site somewhere that gives a more detailed description of all the crafting abilities... www.d20srd.org might help you out
