The Weeping Colossus
Board

The infamous (and mostly to-scale) Weeping Colossus boss dungeon from the Princes of the Apocalypse module. Featuring hidden creatures, ambience, and the Colossus itself! Use for your own cool lava dungeon or in conjunction with the module.
(Feel free to trash the Colossus itself and replace it, it’s very simplistic for optimization purposes)
