Has anyone used fiction writing techniques to improve how they play their roleplaying games, and vice versa?  Me, I used to read a lot of fiction writing books back when I had aspirations of trying out fiction.  These days, I prefer to get my creative jollies out in RPGs, but the stuff I learned in those books - strong characters driving the plot, especially - has really improved my game, both on the player and the GM side.  Has anyone had this kind of experience before?

You'll also want to change Aspects so they continue to fit so you can invoke/compel them in-game and have it make sense.

Yes, quite understandable. But I still think ranged webs doesn't model the Spider existence closely enough. It's Fine for others (Like you, TitaniumMan), but for me, I'd rather pull the webbing from my spinnerets manually, more like the spider I emulate.

Note: the character I'm making has a Trouble of "Conflicting Natures", and is expected to at some point be compelled to run off into the woods to do spidery stuff instead of changing back and rejoining the party after a fight. Perhaps it's my concept of the shifter whose creature nature is very strong that's coloring my view of Spider-Man style web shooting.

That's perfectly fine.  Even so, you don't have to use Breath Weapon like an attack if you do take it.  Just take a -1 Webbing version cleared with your GM and fluff it as pulling the webbing from spinnerets.  Breath Weapon reads as a "self-generated projectile".  Just take out the projectile part if you so choose.

Well, I'd tend to prefer what you've described over someone with spider-man style web-shooters; it feels a bit more real to me.  (And more interesting; the trouble aspect in particular.)

Then again, I was never much interested in superhero comics, so perhaps that's coloring my views.

Hey, Sylene's a spiderwoman who's undergoing withdrawal, she's got enough troubles besides her Spider-Man style webshooting :V

I play a spider-esque creature.  We simply turned Breath Weapon into a -1 Webbing power that let you get a free tag with the Sticky Aspect.

I'm just thinking off the top of my head, so I haven't really thought out the process...what if a Stand was an IoP?  Give it a bunch of powers and what-not.  You'd want to give it a toughness power or something because instead of making it indestructable, it would share the characters Physical stress box.  Maybe an extra discount on the IoP for that.  Although since Stands are invisible to most you'd lose the discount for "obvious item", so it'd even out.

Mechanically, that might be the best way to approach it.

Does one person have several Stands that can do different things?  How many Stands can a person tap into at once?

It's usually one Stand per person, though there are Stands that can break up into multiple bodies.  One Stand was actually comprised of six tiny spirits, and another manifested itself as particles that the user could bake into food to make it tastier.  Other Stands have even manifested as mold or a radio tower.

I'll go into more detail, then.  Hamon is a martial art that focuses around mastering the body and harnessing the power of the sun to fight vampires.  By controlling their breath, Hamon practicioners can enhance various biological aspects of their bodies, like nullifying pain or slightly extending limbs by disconnecting joints temporarily.  They can also infuse and transfer energy through objects.  Water is especially effective for this - Hamon is also known as "the ripple" since energy transfers like the ripples in a lake.  In the first demonstration of Hamon, a user was able to strike a frog sitting on the rock, transfering all of the power to the rock and shattering it, leaving the frog unharmed.  It's very effective against vampires and undead by transfering life energy into their bodies and destroying them.

Stands, meanwhile, are a manifestation of a person's spirit, said to be comprised of the same life energy Hamon users tap into.  It's called a Stand since the spirit stands next to you when it appears.  Only Stand users can see Stands, and they tend to subconciously attract each other.  Those who can't see Stands usually consider their activities to be paranormal, like upset ghosts haunting a house to use an example.  Stands are usually humanoid but can come in a variety of strange designs and configurations that represent the kind of spirit the user has.  Their powers usually reflect the user's hobbies or personality traits, but they manifest in strange ways.  Some of them include supernatural reflexes, freezing time, summoning small bodies to kick bullets towards targets, diving through ground as if it was sand, creating portals that can be unzipped via huge zippers, and so on.

Stands have several rules that govern them - only Stands can hurt Stands, any damage a Stand takes is transfered to the user as well, and they must be maintained with the user's breath.  Furthermore, just because a Stand can't be seen by normal people doesn't mean its powers can't manifest in the real world in a variety of ways.

That's why the GM's there, to shut it down if things get too wacky.
