I bought this as a pdf and printed it on foam board using GMP and PosterRazor so I could use each room separately. My players loved this dungeon! The portals follow a logic for how you get from one room to the next and the colored bits (e.g. portals, dragon heads, fountains) are coordinated enough that it really lends itself to a puzzle challenge. And the elements of both sides of the map have enough elements that use the same color scheme so you can connect them within the same dungeon. There's a lot of replay value here and this map is a breath of fresh air from the traditional arcane dungeon (i.e. alchemy lab/library/magic circle/wizard tower).
