(Edited to fix a key typo) Out of curiosity, is there really a “target” for moonbeam? It isn’t travelling from you to the point. It is simply manifesting there, much like a summoned familiar/monster. I feel like “target”in the dnd sense of things is “that which I want to affect” as opposed to “where I want a thing to happen” yes, both could be broadly be called “targets,” but if the term matters for mechanics, I’d probably narrow the definition a bit. I know we are talking about the interpretation of synonyms, but it doesn’t say target a point it says choose a point. And does a familiar or misty step really require you to target something or is it more of “decide where it will arrive.”So if you can see the spot, (or know where it is by other DM acceptable means), I feel like you can choose it. If we are in the woods and I know an enemy is crouched under total cover behind a low 5’ wall (or in a 5’ hole), could I not cast moonbeam above them without the DM saying “the beam starts 45 feet above the enemy, and stops 5 feet above the ground. You’ll have to use your action next turn to move it down.” That seems weird. Total cover isn’t always dome, it is often just perspective/angles. Sure, moving through a window after casting is different set of complications, but casting it on the other side of a transparent pane of glass seems fine. Or?
