Subjecive Gravity Shenanagains

[The Sideromancer]

Basically, this thread is for fun things to do with subjective gravity.

For example: An intelligent item chooses its gravity, and uses that velocity to move other objects/creatures, despite being normally unable to do so.

What if I mentally commanded gravity around me to get so heavy that I create a black hole? Suicidal, but can I do that and have it work?! @-@

What are the relevant rules for subjective gravity?

Subjective Directional Gravity: The strength of gravity on a plane with this trait is the same as on the Material Plane, but each individual chooses the direction of gravity's pull. Such a plane has no gravity for unattended objects and nonsentient creatures. This sort of environment can be very disorienting to the newcomer, but it is common on "weightless" planes.

Characters on a plane with subjective directional gravity can move normally along a solid surface by imagining "down" near their feet. If suspended in midair, a character "flies" by merely choosing a "down" direction and "falling" that way. Under such a procedure, an individual "falls" 150 feet in the first round and 300 feet in each succeeding round. Movement is straight-line only. In order to stop, one has to slow one's movement by changing the designated "down" direction (again, moving 150 feet in the new direction in the first round and 300 feet per round thereafter).

It takes a DC 16 Wisdom check to set a new direction of gravity as a free action; this check can be made once per round. Any character who fails this Wisdom check in successive rounds receives a +6 bonus on subsequent checks until he or she succeeds.

I've no idea about PF, but if it's that subjective, I'd suspect it only applies to you (unless you're talking about a spell, in which case I suspect it has defined parameters and the "subjective" is direction-only).

However, it's irrelevant: once you're consumed into a black hole, it'll be very tiny and will only last for a relatively short period of time. That said, it might could power a starship for a day or two (I dunno - I haven't worked out the energy output of one "you" of blackhole).

(I think you're big enough, but I'm rusty on my black hole research - really rusty.)

EDIT: and based on the rules above, this can't be done in PF anyway - it's not big enough. If my really off-the-cuff calculations are correct (and I don't guarantee they are) that's enough to go about 35 mph, compared to terminal velocity of 120+ on earth. So... not really all that strong of a gravitational force. At least I think. But I'm being distracted by two kids and my own exhaustion so... I'unno. Physicists speak out.

well, the rules are more mundane than my imagination again. XD

Dancing with subjective gravity might be fun. It might also result in injuries.

If you want to fly slower than 150' you need 2+ people hanging on to each other, imagining different directions of gravity. Coordination would be important.

Zero-G for nonsentients/unattended items means that you'll have difficulty with some processes. Brewing, cooking, etc. I have no idea how your water supply could work.

You could go for a nice stroll through the air with your friend by walking on each other's feet, so long as you're roughly the same weight.

How does Reverse Gravity (the spell) interact with subjective gravity? I feel like that might lead to a few shenanigans of its own.

Gravity varies based on mass. Here, you can have gravity without mass. Keeping the Gravitational Constant the same stops people/things from spontaneously imploding, but you can still apply whatever force you want to yourself.
