Same as Evony Age 1, the Wall is your first line of defence but a naked wall is as good as being without one.
The wall has spaces for fortified unit which add defence to your city. These are very important and should be constructed first BEFORE you upgrade your wall to the next level. A wall without defence is of no use at all, its as good as not being there.
Each level of wall upgrade will give your more spaces. These spaces should be used for adding fortification straightaway before you upgrade your wall to the next level.
In the event of an attack, your Wall and fortified units will be your first line of defence. If your gates are closed at the rally spot, then only your Wall and fortified units fight. If the gates are open, the troops garrisoned in the city also take part in the battle.
Below are the space requirements for each type of fortified unit.
Unit types Traps, Abatis, Rolling Logs & Defensive Trebuchets are for one time use. i.e. they will be destroyed after the battle depending on how many are actually used. A small number of them will be repaired depending on your research level for technology “Machinery”. Archer’s Tower are the only unit type which will require reconstruction if they are destroyed, not used (like the others). They also have a good range and naturally are more popular amongst players.
In my personal experience, I have found the below combination to work best and are the more cost effective provided there are a decent amount of troops in the city (300k Archers, 200k Warriors, 50k Swordsmen, 50k Pikemen) for defence and the gates are open:
- Traps: 1000
- Abatis: 1000
- Archer’s Tower: 17333
- This combination is for a level 10 wall. I do not use Rolling Logs since they are too expensive for mass build and defensive trebuchets take too long to build.
Any troop which is not able to overcome the basic wall defence within 100 rounds of battle automatically die and the attacking hero looses 5 loyalty points. Practically, this can only happen in case of a scout bomb, where large numbers of scouts are send on attack to an enemy city. A scout has no attack and hence is not able to overcome the basic wall defence. This is change from Evony Age 1 and players accustomed to Age 1 tactics fail to realise this difference.
