Extensions

Extensions can be obtained from the shop, the crate, or the blacksmith stations.

At most 3 extensions can be applied to each wagon. Once an extension is added, it can only be removed at the Blacksmith Station and cannot be replaced when adding new extensions.

Some extensions are not compatible with some wagons, and the extension effects may differ depending on the wagon. Please refer to the individual wagons page for details.
