It doesn't!Okay, but now that leads me to the next question. Why does not treating Darkness as an opaque ink-blot allow creatures to see through walls? I don't understand it that way, either.![]()

Claim A: "the Darkness spell needs to be an opaque ink-blot because otherwise creatures can see through walls."
What I was trying to say: "I'm not saying (Claim A)."
Hopefully that makes it clear? I do not think either of the interpretations of the Darkness spell as creating opaque or transparent darkness leads to creatures being able to see through walls.
I do think that the basic rules have an inconsistency, where the addition of silhouettes to the vision rules violates the rules for the Blinded condition (by letting observers see backlit creatures they are effectively Blinded to), but not adding silhouettes to the vision rules causes backlit creatures/objects/walls to fail to interrupt an observer's ability to see the lit area behind (meaning the creatures/objects/walls must not be opaque).
Does that make sense? (Same question for @FitzTheRuke.)
