Fortified Wall

Overview
Fortified Walls are an improved defensive structure for towns that allow your town to secure areas. Unlike normal walls you could build out of blocks of your own, this structure prevents enemies from burrowing underneath it, forcing enemy players to either go over the wall, or through it. This makes walls incredibly useful in helping secure areas and preventing subterranean assaults. Walls have hit points and can be destroyed, they can also be built next to towers, making them very formidable.

Constructing Walls
A fortified wall "segment" only takes up 3 block wide x 10 blocks high x 3 block length. This allows walls to be placed in any area and configuration much like other structures. A wall "section" is 1 block wide x 6 blocks high x variable blocks length. See the tutorial below for placement considerations.

When you place a wall using the /build wall, no matter the length of the wall section, it will be considered a single wall for war purposes. If any segments of the wall are destroyed during war, the entire section created during that /build wall placement will also be destroyed.

Wall Costs
Each fortified wall segment (3x10x3) currently costs 100 coins. A single 3x10x3 segment will end up costing 200 due to the logic of a start and end position being build in the same 3x10x3 area.

Example: For a wall length of 100, if you build two wall sections, each of length fifty, it will cost [(100 * 100) * 2] = 10000. When attacked during war, there are 2 wall sections of 50, each with its own hit points. If one of the wall sections is destroyed, 50 segments will be destroyed.

Every chunk that has a wall section in it costs 50 coins per day in upkeep.

If you decide you have placed your wall incorrectly, you can erase the wall by using the command /build demolishnearest*
