Your innate power sustains your life force. You can alter your body to match your surroundings, allowing you to withstand punishing environments.
- You ignore the effects of extreme climate, for example high altitude, heat and cold (but not cold or fire damage).
- You only need to eat, drink, breathe, or sleep half the regular needed amount. To gain the benefits of a long rest, you can spend 4 hours engaged in light activity, rather than sleeping during any of it.
