Just had a thought. Assume this all happens on one turn via ready actions.
Before turn: PC1 uses ready action to ready a 'Prismatic Wall' spell targeted 10 feet above the ground where the enemies are. It gets angled horizontally so it's parallel-ish to the ground (5-feet would potentially have other enemies occupy it negating the spell).
Start of turn: PW is cast.
PC2 casts 'Reverse Gravity' on the enemies beneath the wall. The enemies proceed to float upwards and into the PW. Once they've hit the apex (at least for that turn), PC2 dismisses the Reverse Gravity, dropping them down and through the PW again, as well as having them take impact damage from falling.
Would this be an effective use of the spells? Would this even be possible? How easy would it be to have this go wrong?

I swear I've seen this exact same question within the past few days...

I don't think readied actions are exactly necessary, but yeah this could work. Prismatic wall uses the word "attempt" to pass through. So there is an argument to be made that forced movement doesn't trigger it.
Also of note, the Wall is automatically vertical unless it is a sphere, so you have to do that. If the DM decides this works, reverse gravity covers more than enough height to pass through the bottom and top of a suspended prismatic sphere, which enemies will pass through in both directions. Could be the most devastating combo dealing 200d6 multi element damage, then sending the petrified target to another plane.
My party did something like this. Prismatic Wall is a nasty, powerful spell of 9th level via a scroll. Very tough combo to beat.
Your main issue is that reverse gravity is too weak a spell at the levels this combo becomes likely.
This combo should not work on anyone that can fly - the spell just reverses gravity and the whole thing about flight is that it lets you ignore gravity.
If someone can fly then the whole dynamic changes anyways; but RAW I'm pretty sure flight doesn't matter. As for Reverse's power... You're not really using it for the power. The damage is nice, yes, but what you really are looking for is to force them into the wall. Technically any spell that can move foes would do, but RG has the unique property of making it so the only way to save against it is to have something to actually grab on to. So you could have all your saves at 99 and roll a nat 20 and still get picked up because this happened when you were standing on smooth marble when it happened.

Indeed, Prismatic Wall doesn't have the usual language of "first time on a turn"
Also, bonus points for another player casting Wall of Force so the enemies take fall damage in both directions.
You sure? I don't see a rule saying it has to be vertical. Heck, I *could* angle it if need-be as well.
The rule is right in the spell: "A shimmering, multicolored plane of light forms a vertical opaque wall..."
Oh... Okay.
