Devil's Sight may not work, but a Bat familiar has Blindsight 60ft. You could have it perch on your shoulder and use its sense instead of your own, though your DM may impose a penalty depending on how you intend to use it. Trying to walk around when your vision doesn't align with your eyes can be disorienting.
Hey guys, I just wanted to know if you can see in a fog cloud if you have devil's sight?
Nope, fog is not darkness. Fog would be a physical barrier made of water vapor.
IMHO, Earthdawn is still the best fantasy realm, Shadowrun is the best Sci-Fi realm, and Dark Sun is the best D&D realm.
