Your chapel gives you 100% attack on barbs if your attacking a smaller player faith/morale will be alot lower as your trying to hit something weaker than you if you have another church lvl 2 you get 105% in province, lvl 3 110% faith/morale but only in province and not on tiny villes like 51points where you would get about 31% faith/morale.. In a different province though you will need a church.. lvl 1 to get 100 % , Strategy - Defence in churches 100% must otherwise your dealing with tiny nuke offence force with limited capability
