Okay, it's not technically a black hole I'm talking about, not in the strictest sense.
In my current campaign, I'm adding new powers and such to a lot of common enemies to spice them up; some of these powers are stronger or weaker versions depending on the scale of the encounter.
One of the abilities I'm considering is an "AoE" gravity effect that essentially makes a combat maneuver check to pull everything within the radius closer. Until now, monsters I have considered using this with have this effect centered on them (mostly the ones with lots of tentacle attacks), but I'm wondering if it could be used as an AoE burst effect like a spell. A secondary effect I am considering is that as long as the gravity well is active, creatures in the effects radius must hold their breath or suffocate, representing the lack of air in that area.
Obviously, altering the DCs and such with these abilities and carefully choosing the creatures that use them has a lot to do with the CR of the encounter, but what level would you as a player expect a DM to throw these at you? As a DM, what level would you plan to use these abilities on your players? Do you think it even matters as long as the numbers aren't ridiculous?
Just to make sure I'm understanding this right, your basically talking about an implosion effect, where you have a point of origin, and it pulls things in towards it?
If that is the case, pretty sure I've read a spell/metamagic feat that did exactly that. If nothing else, you could create a spell/power/whatever that allowed you to select a specific square, and then have it roll a combat maneuver check to use the reposition maneuver on anything within a given range, with the restriction of creatures/objects affected must end up closer to the point of origin than they began.
If you really wanted to be evil, make it so affected creatures were then considered grappled, to make it harder to escape.

Not sure why you feel this has to be a "gravity effect". Frankly the introduction of any semblance of real world physics into this is probably going to have results you don't intend. For example, I don't see why you feel a gravity effect would remove the air from an area.
It's just a custom magic spell. It draws people closer magically. It uses the power of magic to do it, not gravity. Once you say it's gravity, then your players are going to start thinking "wait, why would a gravitational field have that effect?"
I seem to recall a spell that did something very similar to this in a splat book or something.
Just write up the spell effects, figure out how powerful it is, assign it a level and you're good to go.
Black holes are gravity. A black hole would create a vacuum effect, among other things. I use the term gravity loosely. Also, it's a game where unicorns cast spells and creatures drift in and out of various planes of existence; I think certain allowances can be made.
The idea came from playing too much Borderlands 2; singularity grenades (and phaselock if you go "motion"). If this exists elsewhere, a nudge in that direction would be cool.
I'm also lamenting the lack of Baleful Teleport in core rules. I would have sworn it existed.
Sounds very Romulan . . . never a good plan they always loose.
The first thing that came to mind was using Interplanetary teleport offensively.
I know you can't use it offensively and can't send someone without going yourself. It was just a though.
Seriously though if you're not on the prime or a black hole exists coterminusously to the prime also you could planeshift someone to within 500 miles. That should be enough to get them stuck in it's gravity well. Assuming they can't teleport themselves.

A vacuum effect (a difference in pressure causing air to be sucked in one direction) isn't the same as a vacuum (total lack of air).

Back in the 2e days, I created a spell for my home game that was kinda like this (and what the OP is asking about). The spell essentially opened a small Gate to the quasi-elemental plane of Void. Sucked everything to one small point. Flavor-wise, this could be a small portal to the void between worlds.
To figure out the power level, we can break down the various effects: AOE CMD check sounds like Black Tentacles to me. Opening a portal to the void could be a Gate, but not as big or powerful. So maybe more along the lines of a Plane Shift? Everything falling/being sucked into a single point, would feel like a Gust of Wind, maybe... but probably more like a Reverse Gravity that directs "in", rather then "up".
So... Black Tentacles: sorcerer/wizard 4, Gate: cleric 9, sorcerer/wizard 9, Plane Shift: cleric 5, sorcerer/wizard 7, Gust of Wind: druid 2, sorcerer/wizard 2, and Reverse Gravity: druid 8, sorcerer/wizard 7.
So average of about Spell Level 6 or 7, maybe? You can probably tweak with the various effects to raise or lower that.
Cool idea, though. :)

Should this effect be a combat maneuver check or a Will save?

You can make two versions. One telekinetic based (CM check), one complusion-based (Will vs. Enchantment).
d20 Future had singularity projectile weapons. 10d100 damage? Something crazy like that. They were for ship to ship combat.
I think Andromeda had them too. Maybe those evil furry guys had them?
