Prior to the Moderately Friendly Update, walls could be repaired using healing items, such as the Honey Poultice.The presence of Hounds being an enemy where walls are important to have could also be a reference to The Three Little Pigs.

The pigs in the story each had a house made of either straw (hay wall), sticks (wood wall), or bricks (stone wall).

The first three kinds of walls could be a reference to 'The Three Little Pigs'.

This also applies to stone walls, but only in multiples of six (6 stone is required to craft 6 stone walls). Since Thulecite Walls only take one Thulecite to build and each wall drops Thulecite Fragments when hammered, the player can make the walls, hammer them down when they get useless and still craft the original Thulecite back as long as they place the walls separately and don't combine any of them.Before they were implemented, Thulecite Walls had a grayish color instead of the current golden one.Once they are broken down completely it can take eight or nine pieces of wall to completely build back up to a top level wall, due to the way the repair function works. In addition, the cost to fully repair a completely destroyed wall is much higher than just breaking the wall down with a hammer, and starting fresh. Likewise using cut stone is a loss versus using another piece of stone wall. Since it ultimately takes six rocks to make six stone walls, using rocks directly to repair a wall is very inefficient. In repairs, one rock will add considerably less health to the wall than one stone wall will. It has 200 health when first built and a maximum of 400 health. It can be attacked to reduce it to first tier and then destroyed, leaving a destroyed Stone Wall. Hammering the wall will yield two Rocks from fourth tier and one Rock from other tiers. A Stone Wall is first built in its second tier but can be repaired (upgraded) into a third or fourth tier by adding another piece of Stone Wall or enough Rocks or Cut Stone.

The Stone Wall is the second strongest of the four walls, second only to the Thulecite Wall. It is crafted as an Item and deployed as a Structure that prevents movement by both creatures and characters.
