Wall

A **wall** makes the distinction between the wilds (plain or forest) and the Monarch's domain, defining its borders and extension. It is also the most critical building of the Kingdom's line of defense against the Greed.

## Overview

The table below shows the statistics of the wall tiers, each tier in a row, ordered from the weakest on top to the strongest on bottom. From the left to the right, the columns provide for each tier:

* a tiny preview of them in Europe (*clicktap on the icons to enlarge*)
* the names used by the community to refer to them
* the price in coins for building them
* a tiny preview of their stump
* the price in coins for fully rebuilding them
* their natural hit points
* their hit points when the blessing has been applied
* the amount of days they can resit to decay (*Two Crowns* only).

## Building

Walls can be built on small dirt mounds found on plains, not too close to trees. Building or rebuilding a wall costs coin(s) and puts up a scaffold for up to two builders work on it—two going twice as fast.

Builders will not build walls if located too close to or behind a small portal, but will however go out right after it is destroyed potentially exposing them.

### Upgrades

Upgrading a wall will increase its hit points. Tier one walls, also known as spikes, are the least reliable wall in the game. A few attacks from one or two greedlings will destroy them. Tier two walls, also known as palisades, are somewhat stronger, but as they are still made of wood, they remain fairly weak against most attacks. The first Blood Moon can easily destroy palisades. The next upgrades, which are substantially stronger, will require (if available) the stone and iron technologies.

### Statue blessing

It's possible to increase hit points on walls even further by activating the Statue of Building, which grants about 80% more HP to the wall. However, builders have to work on the wall for a few seconds in order to activate the extra protection every time the wall is upgraded or damaged. White particles are visible when the magic buff is active on a wall.

A war horn is a mechanism used on strong walls to call military reinforcements from all over the Kingdom.

In order to use it, the Monarch has to order builders to create a rally wall.
With the Horn Hermit on mount, a war horn can be installed atop:

* a tier four wall for twelve coins
* a tier five wall for sixteen coins.

Once the rally wall is finished, a one-coin slot option will appear close to the mouthpiece of the horn.
Using it once will make archers and knights from the other side of the Kingdom come and defend, for one night, that particular wall, staying there until they hear the morning bell.

It's possible to abbreviate this time, and send the extra troops back to their normal routine before the bell rings, by using the horn again with one more coin.
The sound of the horn for calling the reinforcement and sending them back is slightly different.

Using a war horn may be useful:

* before one-sided waves
* when the other side of the Kingdom has already been cleared from the Greed.

Upgrading a rally wall from tier four to five, doesn't remove the horn. But when a wall is destroyed the war horn is knocked down along with it, and needs to be reinstalled if the wall is rebuilt.

Appending a war horn to a wall does not make it more resistant against decay, nor against damage inflicted by the Greed.

## Wall parts

### Back wall

*This section is about Kingdom Two Crowns.*
The back wall is the background inward extension of a wall. It extends behind the entire segment of the Kingdom immediately behind that wall, up to the nearest previous barrier. Made of the same material of its respective wall, it indicates that there is at least one barricade on that direction, before the wilderness.

Except for the central segment, no back wall exists by itself. When a wall has been built, its back wall rises. If the wall goes down, its back wall falls as well.

Shops require a back wall whose material is equal or higher than the technology needed by the shop. For example, a siege workshop requires the stone technology, then it can only appear in front of back wall made of stone or iron, but never in a segment surrounded by a wooden back wall.

### Central back wall

The central back wall is a cosmetic feature associated to the town center.
It's apparently connected to the innermost walls, but actually unrelated to them.

When (and only when) the town reaches wooden fortifications, a wooden back wall appears behind the main tent, without the help of builders.
After that the central back wall can be improved with stone when (and only when) the town attains the stone fortifications level, and with iron (in *Two Crowns*) when the town gets an iron keep.

Building, upgrading, or destroying the walls around the town does *not* affect the central back wall.

### Innermost wall

Innermost walls are those built on the two dirt mounds closest to the town center. Monarchs can get free tier one, tier three and tier five innermost walls, one on each side of the base, if the town center is upgraded to wood, stone and iron respectively. The table below shows the cost of each town upgrade along with its respective wall bonus.

### Outer wall

On each side of the Kingdom the farthest wall is the outer wall. It's where all military units gather, particularly at night.

If the outer wall is not an innermost wall, it has:

* a lamppost with a sign
* a Kingdom's banner, allowing to order knights to attack portals.

Both add-ons are automatically relocated when the outer wall is destroyed or a new one is built further out.

## Damaged

One can tell how badly a wall is damaged from its condition. Small damage to the wall will result in minor fractures running through its structure, while heavy damage will usually result in roughly half of the wall being torn asunder. Builders automatically repair the damaged walls at day, unless the Greed are still attacking it.

### Stump

If the wall is broken down entirely, a stump remains in place and coins must be used to rebuild it, which is much cheaper than having to build it from scratch.

### Decay

 *Kingdom Two Crowns* – Walls may be destroyed by the decay while the Monarch is away from that island. The more days away, the more walls are destroyed, starting from the outer most ones. Higher tier walls can resist for more days.

## Rabbit bush

 *Kingdom: New Lands* &  *Two Crowns* – Expanding by building more walls make any rabbit bush inside the Kingdom borders vanish, even if the stretches of grass between walls would be long enough for bushes to grow.

## Achievement

Receiving the *free* innermost walls on day II grants the following achievements:

As clearly stated in the descriptions they cannot be unlocked if the Monarch directly pays for the walls, they must be received as a gift.
