Map Iconography Glossary
Visual guide to every symbol, color, and indicator on CritForge battle maps.
CritForge battle maps use standard cartographic symbols drawn from tabletop mapping conventions. This glossary covers every symbol, color, and indicator you'll see on your generated dungeon maps.
Room Numbers
Circled numbers appear at the center of each room in GM view. These are hidden in Player View so your players only see the map itself.
- Numbering is continuous across floors in multi-level dungeons (Room 1 on the ground floor, Room 7 on the second floor, etc.)
- Corridors don't receive room numbers -- only named rooms are numbered
- Purpose labels (italic text near the top edge of a room, like "Armory" or "Throne Room") appear when you toggle room labels on. These help you quickly identify what each room is during play
Connection Types
Connections between rooms are drawn as symbols in gaps along the walls. Here's what each one means:
| Symbol | Type | What It Means |
|---|---|---|
| Line with arc | Standard door | A normal door. The quarter-circle arc shows the swing direction |
| Line with arc + lock mark | Locked door | Requires a key or DC check to open |
| Dashed "S" mark | Secret door | Hidden from players. Visible to you at reduced opacity in GM view |
| Gap in wall (no symbol) | Passage | An open doorway with no door |
| Hatched rectangle | Trap door | A floor-level entrance, often leading to a lower level |
| Three vertical bars | Portcullis | A barred gate that can be raised or lowered |
| Two side-by-side arcs | Double door | A wide entrance with two door panels |
| Curved archway lines | Archway / Portal | An open archway. Portals also render as archways |
| Small barred rectangle | Window | A window opening in the wall |
Secret doors only appear in GM view. When you switch to Player View, they vanish entirely unless you've marked them as revealed.
Locked doors show the lock indicator on top of a standard door symbol, so you can tell at a glance which doors your players need to pick or bash through.
Wall Styles
CritForge generates walls in different styles depending on the dungeon environment:
- Architectural walls -- Clean, straight lines for constructed environments like castles, temples, and fortifications
- Cave / natural walls -- Wobbly, organic outlines that look hand-drawn, mimicking natural rock formations. These use variable-thickness Bezier curves inspired by the Dyson Logos cartographic style
- Mixed construction -- Some dungeons combine both styles. A dwarven mine might have architectural corridors leading into natural cavern chambers
- Secret corridor walls -- Rendered as dashed lines at reduced opacity. Only visible in GM view
Wall outlines may include a stone-colored band fill to give them visual weight, especially in the parchment rendering style.
Furniture and Feature Icons
Rooms contain furniture and dungeon features rendered as small symbols or sprites:
Structural features:
- Pillar / Column -- Filled circle
- Pit -- Circle with crosshatch interior
- Pool / Water -- Wavy-line filled area
- Altar -- Stepped rectangle
- Fireplace -- Rectangle with flame symbol
Furnishings:
- Tables, chairs, beds, chests, barrels, thrones, and braziers appear as Kenney sprites (small pixel-art icons) placed within rooms based on each room's purpose
Terrain features:
- Rubble, vegetation, water, and magical effects appear as textured areas or icon markers within rooms
Some features may render at slightly reduced opacity depending on the room's lighting and depth.
Tactical Overlay
The tactical overlay is a toggleable layer that adds combat-relevant information on top of the map. You can enable individual overlays independently.
Threat Zones
Semi-transparent red rectangles showing each enemy's melee reach. These use grid-square (Chebyshev) distance, so a creature with 5 ft. reach highlights all adjacent squares, while a creature with 10 ft. reach covers a wider area.
- Melee threats -- Red (standard weapon attacks)
- Spell melee threats -- Violet (for enemies using melee spell attacks)
- Creature footprint -- Darker red square showing the actual space the creature occupies
Ranged Zones
Amber dashed-border rings showing enemy ranged attack or spell ranges.
Cover Indicators
Cover zones highlight terrain that provides protection:
| Pattern | Cover Type | Game Effect |
|---|---|---|
| Blue diagonal hatch | Half cover | +2 AC, +2 Dex saves |
| Blue crosshatch | Three-quarters cover | +5 AC, +5 Dex saves |
| Solid violet fill | Total cover | Can't be targeted directly |
At low zoom levels, hatch patterns simplify to solid fills for readability.
Movement Range
Blue filled squares showing all cells reachable from a selected token's current position, accounting for movement speed.
Line of Sight
Blue-grey tint overlaid on squares that are obscured or blocked from the selected token's perspective.
Trap Zones
Traps show two distinct zones:
- Trigger zone -- Violet crosshatch squares marking where stepping activates the trap
- Effect zone -- Orange dotted-border squares showing the blast or damage radius
Conditions
Kenney icon stamps on affected squares showing active status effects (poisoned, frightened, restrained, etc.).
NPC and Enemy Tokens
NPC Tokens
NPCs appear as sprite tokens with a colored ring indicating their attitude:
| Ring Color | Attitude |
|---|---|
| Green | Friendly |
| Amber/Orange | Neutral |
| Red | Hostile |
At low zoom, NPCs simplify to colored discs matching their attitude color. At high zoom, you'll see the sprite plus a name label.
Hidden NPCs appear at 40% opacity in GM view and are completely invisible in Player View.
Player View shows all visible NPCs as plain white discs -- no attitude rings or labels -- so your players don't get meta-information about NPC disposition.
Enemy Tokens
Enemies appear as colored disc markers (using the map style's enemy color, typically red) with:
- A type label below the token (e.g., "Goblin", "Skeleton")
- A count badge if multiple creatures share the same position
- Size scaled to the creature's footprint (Medium = 1 square, Large = 2x2 squares)
Enemy tokens are GM-only -- they don't appear in Player View.
Entry and Exit Points
Stairs
Stair symbols include directional arrows (up or down) and a floor connection label showing where they lead (e.g., "Level 2", "Cellar"). Multi-floor traversal shows a small circled number indicating how many floors the stairs span.
Dungeon Entrance
The primary dungeon entrance is marked with a distinct entry point symbol at the map edge.
Ladders
Ladders function like stairs but use a distinct symbol. They connect floors just like staircases.
Depth and Elevation
CritForge uses subtle color shifts to convey depth in multi-level dungeons:
- Entrance level rooms appear at full brightness
- Each level deeper progressively darkens the room fill by about 6%, up to a maximum of 35% darkening
- Corridors are darkened an additional 10% beyond their room neighbors, making them read as transitional "less lit" passages
This depth tinting is automatic -- you don't need to configure it. It helps you and your players intuitively sense how deep into the dungeon a room sits.
Floor Tabs (Multi-Level Dungeons)
Multi-level dungeons show a tab bar above the map with one tab per floor. Each tab displays the floor's name (e.g., "Ground Floor", "Cellar", "Upper Floor").
- The active floor tab is highlighted
- Stair connections display labels like "Stairs to Cellar" so you can quickly see where vertical connections lead
- Clicking a stair connection navigates to the linked floor and centers the view on the corresponding arrival point
Color Reference
A quick summary of what each color means across all map layers:
| Color | Where You'll See It | Meaning |
|---|---|---|
| Cream / parchment | Room interiors | Floor fill (parchment style) |
| Dark charcoal | Between rooms | Void / solid rock |
| Brown | Wall outlines | Structural walls and door frames |
| Red | Tokens, threat zones | Enemies and melee danger areas |
| Violet | Tactical overlay | Spell melee threats, trap trigger zones, total cover |
| Blue | Tactical overlay | Cover, movement range, line of sight |
| Amber / Orange | Tactical overlay, tokens | Ranged zones, hazards, neutral NPCs |
| Green | Token rings | Friendly NPCs |
| White | Player view tokens | NPC markers (no attitude info) |
Tips
- Toggle overlays independently. You don't need all tactical layers on at once -- enable just threat zones for combat planning, or just cover for positioning analysis.
- Use Player View before sharing your screen or exporting. It strips out GM-only information like secret doors, hidden NPCs, enemy positions, and room numbers.
- Zoom matters. Some details (NPC names, hatch patterns, sprite art) only appear at higher zoom levels. If something looks like a plain colored disc, try zooming in.
