Magma Flow[]
By Peter Cobcroft at GameBoardGeek.
An added level of detail to help work out direction of lava more easily.
When adding any kind of non-natural room, roll a D6:
| 1-3 | Flammable door (not stone or magical) |
| 4-6 | Non-flammable door (stone, magical, crystal etc) |
| Age | Modifier |
|---|---|
| Age of Civilisation | +1 |
| Dwarven Civilisation | +1 |
| Miners other than Dwarves and Druegar | -1 |
| Breeding Group | -1 |
| Dungeon Master | +1 |
When lava events occur (volcano etc) and start filling the map, the flow is stopped by non-flammable doors and will fill up the area until pressure (if applicable) causes the magma to move upwards.
