lightning(Q33741) has a nice statement with has effect(P1542)=thunder(Q83301).

heat lightning(Q1993841) should probably have one that notes its absence. I used does not have quality(P6477), but that seems suboptimal as that property completes has quality(P1552).

I suppose we should find more samples before moving ahead with this. Please contribute. (Add your motivation for this property here.) --- Jura 16:35, 5 August 2019 (UTC)

Try it!
Some of the subclasses of items with has effect (P1542) might be good candidates for this properties, i.e. cases where the subclass doesn't have the effect whereas the class does. --- Jura 09:53, 7 August 2019 (UTC)
