Survival Mode Improved - SKSE is an SKSE plugin implementation of Survival Mode Improved. Survival Mode has been rebuilt from the ground up utilizing C++ (CommonLibSSE-NG) rather than Bethesda's much slower scripting language, Papyrus.

This SKSE plugin is built using CommonLibSSE-NG, and is compatible with versions 1.5.97 through 1.6.659 and up. (Not VR)
Please be sure that you have the appropriate versions of the requirements below.
- Address Library for SKSE
- SKSE64
- CC Survival Mode - Yes, you still need the survival mode esl for this. It pulls and uses many forms from said file.
Soft Requirements:
- I HIGHLY recommend you use some sort of Crash Logger. I don't expect there to be crashes, but you should be using one of these regardless as it will help you and/or mod authors diagnose issues.
- Survival Control Panel is still suggested so that you may modify warmth ratings, and enable/disable features such as arrow weight, sleep to level up, etc.
Regarding crash logger, should you ever run into bugs or crashes, please refer to the F.A.Q on how best to report these.

- Campfire - Integrated compatibility
- Campsite - Integrated compatibility
- Undeath Remastered and Classical Lichdom - Integrated compatibility (All needs will stop when you become a lich.)

- Adamant - A Perk Overhaul (or other perk overhauls) - Please make sure these mods load AFTER SMI.
- Mundus - A Standing Stone Overhaul (or other standing stone mods) - Please make sure these mods load AFTER SMI.

Cold
- Overall, a bigger emphasis is placed upon weather than before. Progression should match SunHelm’s cold pretty closely.
- Cold progresses 85% slower for vampires.
- The Reach is now its own region separate from the “cool region”. It is just slightly warmer.
- The health damage penalty for freezing water has been drastically reduced. It was way too intense.
- The warmth rating effectiveness is capped at 80% (This means it maxes out at reducing cold rate by 80%)
- Seasons have been added. Each month has a multiplier tied to it, and will affect the temperature.
- The Cold widget will now only display when the ambient temp is at least chilly.
- Nords are now 15% resistant to the cold, and Khajiit are 10% resistant. (Down from 25% and 15%)
- Argonians' weakness to cold has been removed. It was unfair to have them be the only race with a racial debuff. There is even lore to back this decision up. (See “On Argonians”, A book in ESO)
The cold stages are as follows:
- Warm - Health Regeneration +10%
- Comfortable - No effect
- Chilly - Total health is reduced
- Very Cold - Total health is reduced. You move 10% slower
- Freezing - Total health is reduced. You move 25% slower
- Numb - Total health is reduced. You move 50% slower
Fatigue
- As with Cold and Hunger, rate, update interval, and stage values have been updated to be much slower among some other balance changes. Rate is 10pts/hour
- Sleeping restores 30 Exhaustion per hour.
- “Drained” is now called “Slightly Tired”.
- Both Vampires and Werewolves can no longer get the Well Rested Bonus.
- The player can now become "Rested" while sleeping in exterior areas.
The fatigue stages are as follows:
- Rested/Well Rested/Lover's Comfort - All skills improved 5/10/15% faster
- Refreshed - No effect
- Slightly Tired - Total Magicka is reduced
- Tired - Total Magicka is reduced. Skill rate reduced by 10%
- Weary - Total Magicka is reduced. Skill rate reduced by 25%
- Debilitated - Total Magicka is reduced. Skill rate reduced by 50%
Hunger
- Vampires will no longer need to deal with hunger. Instead, the existing feeding mechanic already covers this.
- Hunger rate, update interval, and stage values have been updated to provide a less annoying experience. You will become hungry much slower. Rate is 10pts/hour
- Eating now checks for “VendorItemFoodRaw” for raw food as well. (from Connor’s survival mode)
- Food restoration categories have been reworked with the following values
- Very Small: 30hunger
- Small: 50 hunger
- Medium: 80 hunger
- Large: 150 Hunger
The hunger stages are as follows:
- Well Fed - Magicka regeneration +5%
- Fed - No effect
- Peckish - Total stamina reduced
- Hungry - Total stamina reduced. Melee attacks are 10% less effective.
- Famished - Total stamina reduced. Melee attacks are 25% less effective.
- Starving - Total stamina reduced. Melee attacks are 50% less effective.
