I noticed when reading Raulothim's psychic lance spell that it inflicts the incapacitated condition but nothing else. As far as I can remember, the incapacitated condition is usually seen as a "rider" to other effects/conditions and not usually seen by itself.
In order to make a flying creature fall, one of only a few specific things are needed:
If a flying creature is knocked prone, has its speed reduced to 0, or is otherwise deprived of the ability to move, the creature falls, unless it has the ability to hover or it is being held aloft by magic, such as by the fly spell.
The incapacitated condition doesn't mention anything that would meet those prerequisites and movement is separated from actions.
An incapacitated creature can't take actions or reactions.
Assuming the creature is not being held aloft by magic, would it still be able to move and not fall since the incapacitated condition, by itself, doesn't meet any of the qualifiers needed to stop the creature from flying?
I want to make sure that I'm not overlooking something because while this seems to be the case rules as written, it goes against my gut instinct based on what "incapacitated" means.
As an adjective:
Deprived of strength or power; debilitated.
As a verb
Prevent from functioning in a normal way.
