Great way to roll down a mountain, or do a barrel in Niagara Falls maneuver. 

 What would happen if you went underwater with it? It says only air can pass through, but matter cannot, does that mean the sphere would flood with oxygen and hydrogen, just oxygen, or nothing.  I honestly think that just oxygen should pass through.

Question, the sphere blocks spell effect from going in or out, does that mean the person inside couldn’t teleport out?

 Person does not = spell effect, they do not move through the sphere, they jump into a seperate plane for an imperceptible amount of time and then they appear back on the material plane in a different location. I do not think anything should be able to teleport in though, as that would defeat the purpose of the sphere.

 It does NOT say air passes through, it says "though a creature in the sphere can breathe there".

As in, it is an explicit effect of the actual spell that refuses to acknowledge the context the sphere exists in.

i made it into a marble...the barbarian fed it to the plasmoid and trapped it in a magic hamster ball!

great fun!

What if a strong enough creature picks up the sphere-enclosed wizard and throws them off a cliff? Does the person inside the sphere take fall damage?

This spell is very existant, not sure what the issue is exactly.

 You see, this is the Basic Rules version of Otiluke’s Resilient Sphere, a spell in the PHB. However, even though I have the PHB, this spell keeps showing up. Alongside Otiluke’s Resilient Sphere.

"Otiluke's resilient sphere () was an evocation spell that imprisoned its target. To Zakharan mages, always reluctant to acknowledge ajami names and accomplishments, the spell was known simply as resilient sphere, and counted among the spells of the universal province." -- sounds like they're the same spell, but I agree that's confusing.

It sounds to me like, unless you brought some padding into the sphere with you, you'd still take bludgeoning damage from things like rolling down a mountain or heavy impacts. Not directly, but from the sphere wall hitting you. Like why you need padding underneath armor.

A player wants to cast around a door then push or dispelled it hoping the destroy the hinges, should i permit this or hard no.

It says no energy can pass through the barrier, so that means the inside of the sphere appears completely black from outside, right? I mean, if no light can pass, then everything beyond the barrier on either side should be blocked out. Basically, wouldn't that make this feel like a pocket realm? You can't see, hear, feel, etc. anything outside, and vice versa, and nothing can affect you through it, so it would just look like a big blob of unknowable black-hole-ness (or like you're alone inside the sphere, surrounded by the blackness). Also, does this mean, since entropy and energy dispersal from inside are suspended due to the complete energy block-out of the sphere, that a wide-range explosion trapped in an empty sphere would be contained and function as a time bomb triggered when the sphere dissolves? Or would it just get absorbed by the sphere as the umbrella "any effect" clause specifies?

if you use catapult on the sphere, then sense each turn is about 2-3 seconds, then catapult goes around 40mph and if you use it on the sphere when you decide to end the spell the sphere would be 200-300ft in the air causing it to kill almost any non-flying creature.

Unfortunately you actually can't cast Catapult on the sphere, because that spell targets "one object weighing 1 to 5 pounds" and a resilient sphere created by this spell weighs 0 pounds.

The sphere is weightless, not the creature inside, so this is a no go. However, if you can get your hands on some beads of force, you can give your enemies a one way ticket for Faerun's most dangerous airline.

if a morphed druid, as a rat, is locked in that, and then he morphes back to human form... Is he dead?

or other spell effects--can pass through the barrier, in or out,

how does this part work in regards to you if your casting a spell like tsunami which has a casting time of 1 minute. If the sphere is cast on you does tsunami fail or end casting or would it continue you just cant cast anything else after that while in the sphere

So could we turn an enemy into something small using polymorph and then cast the sphere and then once inside let polymorph wear off and crush the enemy inside since the sphere doesn't change size or shape  

just dont use it on anything medium or bigger polymorphed into a rat, unless you want to end everything
