// Returns Item property AC bonus vs. Damage type (ie. piercing).  You

// AC bonus.  The AC bonus should be an integer between 1 and 20.  The
// modifier type depends on the item it is being applied to.  
// NOTE: Only the first 3 damage types may be used here, the 3 basic 
//       physical types.
