Below you'll find two versions of all the maps for Cryptmaster. The first is "low spoiler" it contains the floor maps, marked with the locations of Chests, Skulls, Npcs, etc. none of which are labeled (except fragments, which still have their numbers - mostly because I don't think they spoil anything). The second set has the same, but all the nodes are labeled. Skulls are labeled with the answers to their riddles, npcs have their names and the answer to story-required riddles (or boss fights). There are, however, limitations to this.

Most chests appear to be randomized. Meaning you can get one of many items OR a mimic when opening them. Because of that, it is generally not possible for them to have labels. HOWEVER certain chests seem to have static items inside. If I am pretty sure a chest always has the same item it is labeled.

Another note: Fragments move, so you may find them a few spaces away from their marked areas on the map.

Finally, you may need to copy the image url to a browser tab to make out details on the maps with text. A lot of these floors are huge, and Steam simply doesn't make previews large enough to show all the text.

Please note, these maps were put together in 1.033. v1.034 moved a couple of things around (I believe just the N/M skulls and where you get one of the paladin helms). The map should still be 95% correct, but be aware of these discrepancies.

These are spoilered to prevent accidental viewing. Mouseover the little black boxes to see the maps (from there you can copy URLs, etc).
