The Eraser (E) removes terrain from hexes. It is free, and it works in the Hex and Combined views. On a phone it is one of the five tools in the bottom toolbar.
Erase
Click or drag across hexes, or tap and drag on a touch screen. It only affects the layer and scale level you are looking at. Each stroke is one step for undo (Ctrl + Z, or Cmd + Z on a Mac).
Size runs from 1 to 5, as for the Brush, and the two share one setting. Size 1 erases one hex, and each step adds a ring of hexes around it. Press , and ., or use the stepper on a touch screen.
What it removes, and what stays
Erasing a hex clears everything stored on the hex itself:
- its terrain, including a custom colour or icon;
- its side of any wall drawn with the Edge tool;
- its connections, on both ends, made with the Connection tool.
A wall between the erased hex and a painted neighbour stays on the neighbour’s side and is still drawn. To remove it, click the edge with the Edge tool from inside the neighbour.
Points of interest, notes, tokens, paths and regions on the hex stay. To clear the POIs, notes, tokens and paths too, select the hexes with the Select tool and delete them.
On a detailed scale level, an erased hex shows the terrain of the larger hex it sits inside again. On an Underdark layer, an erased hex becomes empty ground, not Solid Rock.
Erasing keeps fog
Erasing removes terrain, not fog, so it never changes what your players see. A Hidden hex stays Hidden after you erase it, and the POIs and notes on it stay hidden with it. Terrain you paint there afterwards takes the same fog. While dynamic vision is on, a hex the party has explored stays explored.
On a detail level, a hex that follows the fog of the larger hex it sits in keeps following it. To change the fog, use the Vision tool.
