Would a slann bsb with the battle banner add +3 to combat resolution? +1 for bsb, +1 for banner, +1 for bonus on banner? Can the temple guard unit it is with add another +1 by taking a banner, or don't they stack? What if the unit champ in the temple guard takes a magic banner? Is this an additional +2? Thanks for the help.
the best you can take is: normal standard on TG Battle standard on slann war banner on either one (as you can only take 1 war banner per army) for a total of +3.
