Fog of war is a Pro feature. You paint it with the Vision tool (V), or let dynamic vision uncover the map as the party marker moves. Either way, every hex carries one fog level, and your players see the map through it.
Your fog is not your players’ fog
The fog you see in the editor is deliberately thin, so you can keep working on fogged ground. Your players see the same fog far darker, and on a Hidden hex, solid:
| Fog level | Your players see | You see |
|---|---|---|
| Revealed | Everything | Everything |
| Explored | The hex dimmed to half, POIs and labels shown | A light warm tint |
| Terrain-only | A light veil; POIs and their names hidden | A faint cool tint |
| Hidden | Nothing: the hex is covered completely | The hex darkened about half |
You always see every POI, whatever the fog. The tints tell Explored and Terrain-only apart, since both look alike in brightness.
To see the map as your players do, click DM View in the View menu to switch to Player View. Reveal Fog in the same menu hides the fog from your DM View while you work; your players are not affected. See who sees which POI for the rules on points of interest.
Painting fog by hand
In the Vision tool’s Fog brush, pick a level and paint over hexes. Brush size works as for terrain. Under Whole map, Reveal All and Hide All set the fog of the whole current layer at once, replacing anything you painted; both can be undone.
On the surface, Hide All only reaches hexes that have terrain or fog already. On an Underdark layer it covers the whole layer, unpainted rock included.
Erasing a hex with the Eraser removes its terrain but keeps its fog.
Dynamic vision
Switch on Dynamic vision and the map uncovers itself around the party marker. The party marker is a token: place one with the Token tool (M) and switch on Party marker in its editor. Drag the token and the view follows.
What the party can see right now shows clear, even on a Hidden or Terrain-only hex. When the party moves on, the hexes it saw turn Explored, so its trail stays on the map. Dynamic vision never dims a hex you painted Revealed. Sight only works on the layer the party marker is on.
How far the party sees:
- Base Vision Range sets 1 to 10 hexes; the default is 3.
- Conditions subtract from it: dawn and dusk 1, night 2; rain 1, fog 2, storm and blizzard 3. The range never drops below 1.
- Distant landmarks reveal lets prominent places be seen from farther away, for example a castle from 6 hexes or a village from 4, if nothing blocks the view.
Sight is blocked by walls you drew with the Edge tool, by unpainted hexes, and by Solid Rock. Other terrain, including mountains and forests, does not block it.
Reveal by uncovers a whole region, every hex of one terrain, or the hexes along a path, with an optional margin of up to 3 hexes on either side of the path.
You can still paint fog by hand while dynamic vision is on. The brush is how you hide something again, or reveal a place the party learned about without seeing it.
Hexes you never touched
A hex with no terrain and no fog of its own counts as Revealed on a map with hand-painted fog, and as Hidden while dynamic vision is on, until the party sees it.
When your players get the change
Fog you paint with the brush reaches players almost at once. Other changes, including Reveal All, Hide All and Reveal by, reach them when the map next saves, a couple of seconds after you stop. See sharing with players.
