So, I have some specific situations in mind and I would like some ideas on how to handle them, with some ideas as to the possible consequences for failure. Thanks in advance for any assistance. Just so you know, they are in the far northern reaches of Jaiman, the Quellbourne area to be exact (up on the 2000' high plateau and heading north into the mountains there), and it is late spring. I would imagine that the area would correspond to Alaska or Norway/Sweden on Earth, roughly. (Terry if I am wrong, please correct me.) So, while it is late spring, it is still very cold, generally above freezing during the day and just below freezing at night.
I am doing this in three "legs": (1) The Plateau - generally flat, but of high elevation, (2) The Foothills - funny enough, they start out a little lower than the plateau but, of course, eventually rise higher, plus there is a small patch of Cold Moors here, and (3) The Mountains - this is the roughest part of the trip, being as much up and down as across. Each leg is estimated at taking roughly 5-days (though they are traveling much different distances during each leg, of course) and will have it's own situation. They are in order, below: (These do not include any creature encounters, as those I don't have any problem dealing with, and I don't want to have creatures in with these, at least not right now.)
Heavy Rainstorm: The group is out in the open when this strikes, up on the plateau, so I don't see them finding shelter so much as making shelter, so survival skill check? If so: What difficulty? And what "punishment" for failure? Colds and such, giving them negatives for several days and slowing them down? Possibly killing a mount or two?
Late Snowstorm/Minor Blizzard: Here the group will be in the foothills of the mountains, so they could possibly find shelter, which is still a survival check. Failure means....? Some Tiny Cold Crits to simulate frostbite?
Avalanche: Nothing too huge, mostly to make the passage more difficult, forcing the players to think of the best/safest way to continue on. Other than some climbing checks, which would be made really difficult for the animals, I don't have any idea of how to handle this.
My main reason for having these things in here are to reinforce the idea that skills and abilities other than combat and combat support are very important and should not be slighted. Though, I do not want to smack my players in the face too hard with this, just make sure they get the point, and hopefully in a fun, exciting game-moment way.
Ooh. I forgot to mention that they will be needing to cross a melted-snow swollen, fast moving river at one point. It is at what would be a decent crossing-point otherwise (damn, I forgot what those were called), but with the increase in the volume of water it is more dangerous than usual. I am sure some animal handling will be involved here, which is probably how I am going to handle this: the PCs have to control the animals which will do most of the work crossing the river. Failure could mean anything from lost equipment, to beings swept away by the current, I imagine. But, again, I don't necessarily want this to be insta-death (though it very easily could be, I know), so how do I handle the situation if one totally flubs their handle animal check and the horse goes bonkers?
