You have superior vision in dark and dim conditions. You can see in darkness up to 60 feet as if it were dim light, and in dim light as if it were bright light. You can't discern colors in darkness, only shades of gray.

Frostfolk are naturally adapted to extreme cold, thriving in temperatures far below freezing. Their bodies resist cold damage, allowing them to withstand icy winds and glacial conditions with ease. However, this adaptation comes at a cost—heat and fire are their greatest weaknesses. Their physiology is highly vulnerable to fire damage, causing them to suffer double damage from fire-based attacks.

In warm environments, Frostfolk struggle to regulate their body temperature, leading to fatigue and potential exhaustion. Exposure to temperatures above freezing can weaken them over time, requiring careful clothing, shelter, or magical assistance to survive outside their frozen homeland. Despite their resilience to cold, prolonged exposure to extreme sub-zero temperatures can also be dangerous if they are unable to maintain their core warmth.

Their society revolves around their resistance to cold, utilizing specialized clothing and materials that enhance their endurance while avoiding excessive heat. Fire, in their culture, is feared and rarely used except in absolute necessity, as even small flames pose a significant danger to them.

If the surrounding temperature drops below minus 50 °C or you are exposed to lethal cold damage, you enter a life-preserving stasis. In this state, your bodily functions slow dramatically—your heartbeat and breathing become minimal, reducing energy consumption almost entirely.

During stasis, you require no food or water and are completely immune to cold damage. You are completely immobile and faintly perceive your surroundings but remain vulnerable to external threats. If an external force disturbs you—such as intense vibrations or direct attacks—you remain defenseless until your body awakens.

The duration of your stasis depends on your Constitution modifier:

• Base duration: 5 days

• Positive Constitution: Multiply by your modifier (3 => 5 × 3 = 15 days)

• Negative Constitution: Divide by the absolute value (minus 2 => 5 ÷ 2 = 2.5 days)

• Minimum duration: Less than 1 day in stasis

Once the temperature rises to a range between minus 10 °C and minus 30 °C, your body naturally begins to awaken. The transition back to full consciousness takes several minutes as your bodily functions gradually recover.

You are incapacitated—you can’t move, speak, take actions, bonus actions, or reactions. You faintly perceive your surroundings, but you don’t benefit from passive perception against threats. You are not considered unconscious, but all attack rolls against you have advantage, and any hit from within 5 feet is a critical hit. While in this state, you do not require food or water and are immune to cold damage.

End of Stasis & Limitations: When the stasis duration ends, but the surrounding temperature remains below minus 50 °C or other lethal cold conditions persist, the body still awakens. Upon awakening, all bodily functions fully return, and the character resumes their normal state—including all environmental influences affecting them.

The stasis can only be used once per month. The body requires sufficient time for full recovery before it can enter the life-preserving state again. Attempting to enter stasis again before the month has passed will fail.
