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
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.
