Weather
Eventually weather tables for each region may be developed, but for now the following system is used.
Procedure
- At the start of the expedition, check starting weather by rolling d6 to determine the starting column, and a d20 for the row.1)
- At every subsequent dawn and dusk, roll a d20 for the current column. The result may cause a change of column, as seen below.
| d20 | Clear (1-3) | Cloudy (4-5) | Precipitation (6) |
|---|---|---|---|
| 1-2 | Re-roll. If 1-2, go to Storms table. | Re-roll. If 1-2, to go Storms table. | Re-roll. If 1-2, go to Storms table. |
| 3-5 | Excess heat | ← Clear | ← Cloudy |
| 6-8 | Clear | Cloudy | ← Cloudy |
| 9-11 | Clear | Cloudy | Light rain |
| 12-14 | Clear | Cloudy | Light rain |
| 15-17 | Clear | Cloudy | Hard rain |
| 18-20 | Cloudy → | Rain (d2 for light or hard) → | Hard rain |
In the winter, rain will be sleet/snow.
Storms
| d10 | Storm |
|---|---|
| 1 | Special storm. |
| 2-10 | Blizzard (winter) or lightning (other seasons). |
Effects
Clear
- Orcs and goblins fight at a penalty. Vampires will be destroyed. Wraiths are powerless. And so on.
Cloudy
- Orcs, goblins, vampires, wraiths, etc. are not affected by sunlight.
Light rain
- -1 to missiles.
- 80% visibility and encounter distance.
- Any invisible creatures can be attacked at -4, as their general position is revealed. (Excludes psionic invisibility.)
Hard rain
- -2 to missiles.
- 50% visibility and encounter distance.
- Any invisible creatures can be attacked at -4, as their general position is revealed. (Excludes psionic invisibility.)
- 50% movement speed, due to mud.
- Double movement point cost.
Lightning
Only possible outside of the winter moons. Blizzard otherwise.
- Counts as the precipitation column. Starting rain is either light (25%) or hard (75%).
- If “Cloudy” is rolled, the lightning storm ends, and the “Precipitation” column is rolled on once more.
Blizzard
Only possible during the winter moons. Lightning storm otherwise.
- Counts as the precipitation column. “Light rain” has the effects of “Hard rain”, and “Hard rain”'s effects are doubled (excluding ability to strike invisible at -4).
- If “Cloudy” is rolled, the blizzard ends, and the “Precipitation” column is rolled on once more.
Excess heat
Only possible during the summer moons. Counts as clear otherwise.
- Double movement point cost.
- Any chances to start a fire (due to carelessness or intention) are doubled.

For the curious, this system was inspired by Chainmail's weather rules.
