Be careful if you retreat without disengage skill, anyone within melee range will get a chance to hit you but not in this case.

• Heavily obscured: Per the player's Handbook, A heavily obscured area blocks vision entirely. A creature effectively suffers from the blinded condition when trying to see something in that area.

• The blinded condition: A blinded creature can’t see and automatically fails any ability check that requires sight. Attack Rolls against the creature have advantage, and the creature’s Attack Rolls have disadvantage.

• Creatures in the fog also can't take attacks of opportunity while inside, unless they have blindsight. From the player's Handbook (p. 195): "You can make an opportunity attack when a hostile creature that you can see moves out of your reach".

Disadvantage works both ways so I'm still saying any creature who is blinded makes attacks with disadvantage.

Ranged or targeting spells can't be made in the blinded state.
