====== 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.((For the curious, this system was inspired by Chainmail's weather rules.))
  - 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 [[calendar|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 [[calendar|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 [[calendar|summer moons]]. Counts as clear otherwise.

  * Double movement point cost.
  * Any chances to start a fire (due to carelessness or intention) are doubled.
