How Fog Works in Hexer
Reveal hexes as players explore
Start with the entire map hidden. Click individual hexes to reveal them, or place a party marker that automatically clears a vision radius. Fog persists between sessions — pick up where you left off.
Four fog levels
Revealed — everything shows. Explored — a dim memory of ground the party has seen. Terrain-only — the land shows, its places stay hidden. Hidden — nothing shows. Paint any level onto any hex, or let dynamic vision mark what the party has explored.
Dynamic vision modifiers
Terrain, weather, and time of day modify sight range. Dense forests reduce vision. Night cuts it further. Mountaintops extend it. All configurable.
Works on every layer
Each of the four layers — Surface, Caverns, Deep Caverns, The Underdark — has independent fog. Reveal caves below without spoiling the surface. Learn about Underdark layers →
Tokens that appear in sight
Give a map token the "In sight" visibility and players see it only while the party can see its hex. The enemy scouts show up when the party crests the ridge, and vanish again when it moves on.
Share fog state live with your players.
You see the full map — every hex, note, and secret. Toggle to the player perspective with one click to preview exactly what they see through the fog.
Generate a share link and send it to your group. As you reveal hexes or move the party marker, their view updates instantly. Players don't need an account — just open the link.
