So I finally get around to do some checking of the available mods:
Ortorin damaging weather (middle script weight mod)
penalty for thunderstorms, ash storms, blight storms, snow storms and blizzards
usually fatigue lost, some damage via spell effect, immunity based on race
Blight infections (light script weight mod)
4 possible diseases in blight storm
Serious weather (middle script weight mod)
penalty for ashstorms ,blight storms ,blizzards
damage via script
modifies weather patterns after defeat of Ur
Weathering Weather (heavy script weight mod)
complex fatigue loss
4 possible diseases to catch
penalty for rain, thunderstorm, ashstorm, blightstorm, snow, blizzard
Erin's improved weather (middle script weight mod)
penalty for ashstorm,blight storm,blizzard, thunderstorm
damage via spell effects
modifies weather patterns after defeat of Ur
4 possible diseases to catch
Endrek weather effects (light script weight mod)
penalties for ashstorm,blight storm,blizzard
(also gives blindness + night eye = same visibility, but worse chance to hit)
I did not check the spell effects itself much.
Now I personally would prefer something that makes more penalties. I really like the detailed fatigue penalty system in weathering weather, but the script seems a bit too heavy to me. What I would imagine is basically Erin's mod as base plus some expansions.
penalty for:
rain - fatigue light
thunderstorm - fatigue medium, blindness + night eye light
ashstorm - fatigue heavy, blindness + night eye medium, disease low
blightstorm - fatigue heavy, blindness + night eye heavy, fire damage, disease medium
snow - fatigue medium, blindness + night eye medium, cold damage very light?
blizzard- fatigue heavy, blindness + night eye heavy, cold damage
plus abot's lightnings for more fun in thunderstorm.
What do you think?
