Open your magic menu, and go to the Powers tab. Select Survival Skills, and then press your Shout key (Z by default). You are given this power after you start Frostfall.
Probably. Frostfall is compatible with almost everything. See here.
It's an optional feature, but yes.
Yes, including unlit Giant campfires. Hit it with a torch or a flame spell / shout. Frostfall is compatible with Sneak Tools by Borgut1337. Dynamic Fires by Woodbyte, however, is not compatible (in the sense that they do the same thing).
Frost Resistance helps reduce exposure, and Nords start with 50%. If you're not a Nord, you can make up the difference later with magical equipment.
No. They have been desert-dwellers for thousands of years, and the assumption could be made that they are genetically disposed to dealing with heat, not cold. In Ta'agra (the Khajiiti native language), "khajiit" means "desert-walker". They don't receive a penalty, however. Nor do any other races. I would like for all players to be on more or less the same footing throughout the game; your actions should be the most important factor dictating your survival capability, not the race you were born to.
Exposure Rate is independent of your time scale. Use whatever time scale you like. This includes using a time scale mod, or setting the time scale yourself with console commands.
Are Vampires (including from Dawnguard) supported? Are Werewolves supported? Does werewolf fur keep you warm?
Followers will use the extra bed rolls in your tent, if you have any. They will also warm their hands near a fire when you are warming up.
Having at least one follower gives you the Will To Survive effect, which grants you an additional 5% Exposure Resistance.
NPCs and Followers are not affected by the cold or exposure.
Frostfall 2.5 added a spell (Kindle) that can restore your exposure at the cost of one firewood. Fire-based magic in general will never be given the capability to restore your exposure for the cost of magicka alone. See here for my thoughts on the issue.
Yes! You must use SkyUI 4.1 or newer, or the Mod Configuration Menu WILL NOT WORK! I cannot provide you with SkyUI tech support; for all SkyUI-specific questions, please contact the SkyUI team. If your Mod Configuration Menu does not appear, please consult the SkyUI Nexus page, and all related troubleshooting documentation.
If you use SkyUI, the Survival Settings configuration power will be removed from your magic menu.
Use Survival Skills, Create Item, and craft some Snowberry Extract. If you don't like this feature, you can turn it off under Survival Settings, Exposure, Water. If you use SkyUI 4.1+, you can open the Mod Configuration Menu, and go to the Gameplay page, and uncheck "Frigid Water is Lethal".
Quivers clip with cloaks super-badly and look dumb sticking out of the top of the backpack. Anything for this?
Try using my optional file, Belt-Fastened Quivers. It won't completely solve the problem, but it does look better (in my opinion).
The latest version of Skyrim. That's it.
Yes. DO NOT clean Frostfall using TES5Edit yourself. It has already been cleaned. You will break it.
You don't have to have it, but there are features that won't work without it. For instance, you need SKSE to prevent exposure gain while in dialogue. This is helpful when talking to particular NPCs in very cold places. SKSE is also a requirement of SkyUI.
Using Frostfall with Script Dragon is not supported. See here.
I'd rather not. A lot of work has gone into getting the Tamriel worldspace to behave the way I want it to. To reverse course now would mean undoing a lot of work. I will happily support a new, tropical or desert-based landmass mod.
No. See note about fire magic, above.
Yes, I can, but I won't. At least, not for Frostfall. I never want to punish the player for doing too much of what they thought they should have been doing. I think that it would be a poor design decision, similar to damaging the player for picking up too many heart pieces in The Legend of Zelda games.
I don't think it's a good idea and would encourage unimmersive behavior (dashing everywhere, jumping continuously). You already do not gain exposure during combat, by default, which simulates this idea.
It was determined that Become Ethereal lasts too long and has a recast time too short in order for this to be balanced, and I can't change the parameters of this shout in Frostfall (since this is not a difficulty, perk overhaul, or cooldown timer mod).
