Church Belief Radius:
Level 1: 4 fields in every direction
Level 2: 6 fields in every direction
Level 3: 8 fields in every direction
Church Cost Structure:
Level 1: 16.000 wood - 20.000 clay - 5.000 iron - 5.000 population
Level 2: 20.160 wood - 25.600 clay - 6.300 iron - 2.750 population(additional)
Level 3: 25.402 wood - 32.768 clay - 7.938 iron - 4.263 population(additional)
Church Build Time Factor:
Level 1 = 5:40:00
Level 2 = 6:48:00
Level 3 = 8:09:36
The actual build time is calculated by the following formula:
([build time factor] * 1.05^(-[level of the village headquarters])) / [world speed]
Church Point Values:
Level 1: 10 points
Level 2: 2 points
Level 3: 2 points
Church Build Requirements:
Level 5 Headquarters and whatever farm level required to hold the population.
Churches can be catapulted but they take significantly more catapults to drop a level than normal buildings. EDIT: When you noble a village the church 'flies away' - Morthy said.
All villages that are not contained within a church radius will have all troops' defensive and attack power reduced to 50%.
This means that you can attack outside your church's radius, as long as the attacking village is inside it.
Defending troops take the church effect of the village/person they are defending.
There is an exception to the above setup/rules. The very first church that you start with will be a church that has a 6 field radius and is 10 points. This church can not be upgraded at any point. In addition, the original church can't be damaged by catapults.
-Yes you can demolish your first church. However it would be a huge waste. As when you build it back, it will still just be the same 'first (non-upgradible) church'. You can only move it to another village if you have no other churches/
-If you lose your first church, you can rebuild it if you have no other churches.
-Churches only effect your own villages, not allies, not others. Only yours.
-This church is a different one to the one that built priests on the early german servers.
-Barbs/Bonus will not be effected by churches (I.E stacking troops)
-All calculations of religion will be done at landing time.
-It takes 400 catapults to destroy a lvl 1 church
167 to take lvl 2 to lvl 1
and 125 to take lvl 3 to lvl 2
Or 600 to take lvl 3 down completely.
This is with against a empty, wall-less village with 0% luck, no morale penalty and religious attackers (religion makes no difference to the defence of target buildings)
