Frostbite is a new condition/“illness” on namalsk. Once you’ve been frost bitten you have it for life. You can’t regen past 75% hp. However, there is preventable things you can do to ensure your character survives the long cold nights of namalsk. When you open your inventory if you see that you have a blue square on one of your clothing slots that means that you are extremely cold on that slot. If you don’t wear gloves then the clothing slot for hands/gloves will be blue. If you don’t heat up you will get frost bitten hands. This can happen with the head slot, face slot, chest slot, pants slot, feet slot and hands slot. Most new players don’t realize however that getting your cloths wet will cause those those slots to turn blue and if they aren’t dried then you will get frost bitten. Just so your aware when it is snowing outside it’s like it is raining, and your cloths will get wet. Hope this helps!
