This guide expects you to follow maps in numerical order, though there are several things you can do in a different order. A numbered marker always refers to the corresponding numbered entry in the text. Apart from numbered markers, the maps also use several icons to depict items you may find that are mentioned in the walkthrough but not singled out as special finds. Shortcuts for speedrunners are not described in this walkthrough: this guide is intended to take you to every single item, puzzle and secret.
A few bracers are actually named Brace in the game, and that is the name I will use in the walkthrough.
Gates refer to doors (whether openable or not) that you can see through. Doors refer to those you cannot see through.
Secret doors refer to any gate, door or wall that can be opened. On rare occasions I may call them secret walls.
Buttons usually refer to the easily visible types: the large button fit into a panel, the square metallic type, or the thin rectangular one. Hidden button indicates either the tiny square ones or a small 'loose brick' in the wall. A rune-engraved button appears as a wall panel with the Grimrock rune (which can be seen above most arches) on it and is most difficult to make out unless you know what to look for. Buttons in the Cemetery are all easily visible even though they are tiny. Buttons and levers are always found on human-made hard (permanent) surfaces, never on natural rock faces, landslide debris, crates and such.
When directed to fall down into a pit, you can refer to the map for the lower level to help you. Except for the Slime Dungeon, these isolated regions are not annotated with numbered markers and descriptions, but the maps can still help you locate items. Descriptions of what to do when falling into pits are given alongside the instructions themselves (except for Slime Dungeon), so you will still be able to follow along.
When instructed to “shoot a projectile” you need to fire either a thrown weapon or missile as a weapon (i.e., don’t drop an item on the top half of the screen).
Except for the early parts of the walkthrough and a few sprinklings here and there, you will usually not be told how many or which enemies you will be facing in each spot. Once you get used to spotting and fighting (or evading) enemies, the walkthrough will stop holding your hand in that regard.
The generalised term skeletons refers to a mix of any of skeleton warriors, skeleton archers, and their pack counterparts.
This walkthrough does not recite the various notes, scrolls, runes and visual cues you can read, and thus does not tell you how the solution to every puzzle is deduced. Solutions are given without any reasoning. If you are so inclined, you can read everything as you are playing the game and pay attention to your surroundings.
Projectiles
If you are using any projectiles, keep a track of their count. Although the game automatically picks up any projectile you shot, there are multiple ways to lose them. One, you equipped a different projectile during the fight, leaving no hands free to pick up the ones you fired. Second, projectiles that land on pressure plates are not automatically picked up (the game assumes you need to keep the pressure plate weighed down). Finally, if an enemy was lunging onto your tile when you killed it, the projectile will land on your tile, not the enemy’s, so you will have to walk forward and back to reacquire it.
Elemental arrows and quarrels will not be automatically retrieved if they hit an enemy because they will lose their elemental properties and become different (normal) items.
Confusion can also occur if you have two characters shoot (say) Rocks. Either one of them may retrieve all of them, and they may not be distributed in the way that you did.
Legend
In the legend below you may notice that Rocks and Shurikens get their own icons but Thrown Axes and Knives do not—they fall into the general Weapon category. It was just easier to create certain icons and not others. For the same reason, all wearable gear is lumped together. The text will inform you what items you will find in each region.
