All maps contain walling, dynamic lighting, local sounds, and canopies where relevant to a map. Many of our map packs contain third-party modules to add additional tactics and dynamic play, these include:
![]() Levels allows instant transitions between floors, or moving your token on top of canopies, creating vertical elevation on a map! |
![]() Mass Edit allows drag-and-drop pre-fab buildings and modular dungeons, as well as helping create dynamic environment changes! |
![]() Tile Scroll lets us create moving tiles and canopies, adding scrolling or rotation to static images to create more dynamic animated maps! |

This module will be updated to the latest stable version of Foundry after supporting third party modules are updated. This module is compatible with earlier versions of Foundry, but requires manual installation of older versions of any third party module dependencies. |
