Cold Blooded [PCF]

As a cold-blooded creature, you cannot generate your own heat, and are normally the temperature of your surroundings. You have the ability to survive some what comfortably in temperatures from -10ºC to 55ºC (14ºF to 131ºF). 

If you are in temperatures of 38ºC (100ºF) or higher, you gain 10ft of movement. If you are in temperatures of 4ºC (40ºF) or lower, you lose 10 movement speed.

Your body temperature may also be affected by spells or damage. This feature does not stack with itself, but may stack with the environmental bonus or penalty.
      - If you are hit by fire damage, you gain 10 movement speed until the end of your next turn.
      - If you are hit by cold damage, you lose 10 movement speed until the end of your next turn.
