Concept: Catapult + Feather Fall

I'm aware this is a stretch on multiple levels.

Catapult targets objects and Feather Fall targets creatures (so strictly RAW this combo doesn't work).
Feather Fall targets creatures who are falling, it negates falling damage, and ends on the creature once it lands.
Falling damage is bludgeoning damage from colliding with the ground too quickly.
Catapult causes bludgeoning damage by having an object collide with something.

Let's say the creature in question also fits the weight requirements for the level of casting catapult: between 1 lb and 5 x (spell slot level) lbs.

If a DM were to allow a creature to be the projectile of Catapult could casting Feather Fall on that creature negate the bludgeoning damage the projectile creature would receive?

Assuming the DM allows the creature to be catapulted my thought is that if you were to cast Feather Fall, the creature would no longer be moving fast enough to cause any bludgeoning damage to an impacted creature. A better combo would be Catapult + Invulnerability.

It's still good for tactical insertions though. It's like a medieval LALO jump.

In general I am more lenient with non-combat spell combos than combat ones.

With combat combos people try to do more than what spells designed for combat can do.  In other words, they try to make something overpowered.   The classic is the drop heavy object for auto-kill.

For non-combat uses they usually are not trying to be better than existing spells, but instead use magic to do something weaker than existing spells.   They simply do not have the spell they desire prepared/known.

Well, maybe I'm the exception there, but in the right context Prestidigitation used exactly as intended (to clean surfaces) beats a full loadout of combat spells in terms of raw power.

fog cloud + faerie fire 
You can see them, but they can't see you or the rest of your party.

Faerie Fire negates invisibility, not obscurement.

But if they are glowing from faerie fire, you are likely to see them before they see you.   I would rule that faerie fire on you decreases the obscurement you have by one category.  

But that's still a weapon you can get past any guard or magical defence to assasinate a king ;)

Does the spell allow you to make an attack or allow an enemy to make a saving throw?

No?

Then that spell cannot be used to damage an enemy.

General rule.

 in other words your saying no fun at the table lol j/k

so if there is a lever that opens a concealed trapdoor someone steps onto you take no damage from it if the lever is pulled with mage hand?

 Traps, even trapdoors, generally evoke a DEX saving throw.

 I'd agree with this here. For the people attempting to turn level 0-2 utility effects into insta-kills and such? Nay, you're not getting that, and results may vary in how playful your DM is. Optimally, they do give you a little bit to work with, like that dehydrated mouth idea, but you should not be using create or destroy water as a greater Desiccate. 

However, if you can feasibly turn a tier 3 or 4 spell into something lethal... maybe. Like, heck it, you're already spending this level of spell, why not?

The real trick is casting true polymorph first, then catapulting them away because it's embarassing even if they survive

 Couldn't you target Catapult on, say a board?

the launchee takes a short plank, and drags it with them on a rope. Cast Catapult on the board and hop on! since it is neither being worn nor carried, rather, stood on, it should work? maybe? idk.

Catapult can only work on an object between 1-5 lbs.  No way a board plus an adventurer is going to work.

Actually while the nose and mouth may be "open" that does not mean the water would be lethal. Your lungs/stomach may still be closed, that's why you can open your mouth in a pool and not drown. There are other ways to use the spell but as a dm I would never accept this as an instant kill.

 If you hop on the board once it's already been catapulted, wouldnt that work?

At that point, the board is traveling fast enough to deal 3d8 points of damage to whatever it hits.  No you're not going to hop onto that board, and if you somehow could it would hurt.

 But like, jump, and cast it a split second before your feet hit it. The board should only be travelling a few inches before you land on it, probably not enough to deal damage, especially since the board wouldn't be at top catapult speed after going only 6 inches or so.

i'd rule either you take the damage, or nothing at all happens. if its not going fast enough to damage, then the spell failed because you're stepping on the board.  there's no acceleration phase written into the spell. it goes from a harmless board to a full-speed projectile the instant the spell is complete.
