"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?

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.


Immunity to the Blinded condition does not allow you to see through Fog Cloud, etc.

If the effect does not specifically impose the Blinded condition, a creature immune to the Blinded condition is still affected by the Fog/Darkness/whatever.

Rules only do exactly what they say, so while the creature is effectively suffering from the Blinded condition, they are not actually Blinded, so their immunity does not apply.

    \$\begingroup\$ Yes, the question has both a positive and negative variant of the same question, so adding a quote of the question being answered would help to clarify. \$\endgroup\$
