The description of the Slow spell says:
You alter time around up to six creatures of your choice in a 40-foot cube within range. An affected target's speed is halved…
It alters time around creatures and reduces their speed to half. Could this be used to affect a falling creature?
Which of the following accurately describes how the Slow spell interacts with falls and falling damage?
The creature moves at half speed and so falls at half speed, taking half damage
The creature moves at half speed but their relative time bubble they move at regular speed. They hit the ground after twice the time but still at the same speed and damage.
They are in free fall for double the time but gravity interacts for the duration. So actually they personally have double the speed. They take additional damage?
They fall at the same rate (aka their bubble continues falling) but inside it they impact at half (double?) speed and take half (double?) damage.
The mental picture for me is definitely the slow-time effect where they are in a bubble of slowmo, slurred speech and all. So I feel like it would have some interaction, but I'm not sure what.
Spells in D&D do what they say they do and no more (unless a DM decides otherwise):
How? Like this:
A creature's speed does not interact with the falling rules.
