.... is the assassin vine a tomato plant?
Actually, it's a lot more similar to a Grape Vine. You can even make wine from its fruit, in the correct season.
The rest of the day passes relatively peacefully, some more travelling is accomplished and Charlarn heals the party to the peak of good health. Setting up camp that night, the party does its best to shelter itself from the weather, but the temperature drops steeply during the night.
Severe Cold effects the party. Those with proper equipment (winter blankets at the minimum) need only make one saving throw at DC 15. Those without need to make a saving throw at each of the following DCs: 15, 16, 17, 18, and 19. (A total of 5 saves.)
For each missed save, take 1d6 nonlethal damage. If you take any nonlethal damage, you are fatigued from hypothermia.
Also, feel free to make survival checks to protect yourself from the weather, which may provide saving throw bonuses for the skill user and/or his or her companions. This check can be made untrained, as I recall.
If Iggy takes damage during the night, each time will add one hour to the time needed to get enough sleep to regain spells. Divine casters do not appear to suffer from this problem.
You will be going higher into the pass tomorrow. You may wish to note any changes in memorized spells.
