[RPG] Can you cast Call Lightning while submerged underwater

dnd-5edruidmagicspells

We are running an underwater campaign where everyone is an aquatic race, and most of the campaign will take place completely underwater. Call Lightning says:

"A storm cloud appears in the shape of a cylinder that is 10 feet tall with a 60-foot radius, centered on a point you can see within range directly above you. The spell fails if you can't see a point in the air where the storm cloud could appear (for example, if you are in a room that can't accommodate the cloud)."

Does this literally mean you must be able to see a point "in the air", or could this work beneath the waves?

Best Answer

I would rule that submarine areas could not accommodate a storm cloud.

The sticking point for me is in the example they give:

for example, if you are in a room that can't accommodate the cloud

It seems to me that this spell description really wants this storm cloud to form in normal storm cloud areas, such as while out of doors. Just as a small indoor space could not accommodate a proper storm cloud, I would rule that underwater areas could not either.
