No flips for you!
Not sure what you're getting at, here. Are you saying this refutes me, as 'casts a shadow' isn't exactly clear. If you believe it means 'actively blocks light as real objects do' then, no, I think Sage Advice is full of it and that this is nothing more than a weak appeal to authority. If you mean 'the illusion will have realistic shadows as part of it's creation' then we're in agreement -- you can create the illusion of a shadow, but it's not a real shadow.Sage Advice (as quoted above) says if the illusion includes sensory effects and/or movement, then it casts a shadow.
The defining break I see here is what happens in late afternoon when you create an illusion that would, if real, have a shadow that would extend outside the area of effect of the illusion spell? I say 'no shadow outside the aoe.' What do you think the above says?
Gosh, Misty, if only I had said in the bit your quoted "unless specifically stated" then I wouldn't have that egg on my face. Wait a second....Invisibility is an illusion spell, for what that is worth. Most of the mid to higher level illusions pretty clearly do block things. Most of the lower level ones pretty clearly do not.
This is all covered in that sage advice video linked to above.
