[RPG] Is a creature immune to blindness affected by Fog Cloud (or other Heavy Obscurement)

conditionsdnd-5e

"A heavily obscured area—such as Darkness, opaque fog, or dense foliage—blocks vision entirely. A creature effectively suffers from the Blinded condition when trying to see something in that area."

So is a creature immune to the Blinded condition affected by Fog Cloud or Cloudkill?

Best Answer

Blinded vs "Effectively Blinded"

Blinded is a condition that is inflicted upon a creature. "Effectively Blinded" is a behaviour that a creature must follow even though it is not under the Blinded condition.

Immunity to being blinded only means that they cannot suffer from that condition. They can still encounter situations where objects and entities are obscured from their vision. In those cases the rules for targeting while blinded apply but only when attempting to target entities obscured by the fog.
