Would she be able to create spell components or otherwise add them to the interface without necessarily purchasing them with points, if she knew any?

How much mana would that example force spell cost her?

New components can be created out of available components. Note: Some system defaults are tied into general system processes and are therefore more efficient than manually crafted components of equivalent effect.

Described force spell imparts 1000 joules of kinetic energy to target. Mana to force conversion ratio is 1 mana to 8 joules. Standard projectile spell envelope is 10 mana. Total spell cost 135 mana.

...Is there a limited set of spell components like that?

Hm.  Okay.

There is a finite set of atomic spell components, in total there are roughly five hundred thousand. Most such components are unlikely to be relevant to any given user.

...The set of spell component tied to/benefitting from interacting with system functions, she means?

Affirmative

...Well, she'll cross that bridge when she gets to it.

...Returning to the earlier subject, if she was able to, for example, observe the workings of a magic item, would she be able to then put the components into her spellcrafting interface without expending points?

There is a component which allows for copying observed components and integrating them into the spell crafting interface assuming you have all relevant permissions to invoke them. It requires magical analysis capabilities as a prerequisite.

...She'll get to that later, then.

She turns her power's analytic side on 'herself', full-blast, and then...

She's going to buy both the physical and mental components she previewed; she'll leave the arcane components til later.

The feeling her power returns for her effort feels like a shrug. It doesn't seem like there's anything broken in her from her power's perspective.

The world seems to slow a touch, her body seems paradoxically slower to respond as well. She is also suddenly extremely aware of the position of her body, she can feel each finger each toe how her legs are oriented how straight she's standing.

A thought pops into her mind unprompted... walls usually exist for a reason... why is there a wall there?

Yes, nothing's wrong, but she does want to see the system at work and that's something that's broken-ish.

She's been meaning to get on the other side of that wall for a while now, but it's hard to think and walk, when you're really thinking.

Still, armed with the barest basics, she supposes now is a good enough time to -

augh this damnable slowness.

Well, that's her own darn fault.  She'll just have to hunt monsters about it --

Oh, wow, that's a scary incentive structure.

Still, she probably ought to do something about this situation's...Thisness.

So, as she takes a second per few seconds(subjective) to handle walking and environment awareness, she continues peppering the system with queries.

Is there an off button for enhancements?

Preview: U[Selective time dilation]

Preview: A[Selective time dilation]

System enhancements are typically alterations to underlying biology and therefore cannot be toggled. Some enhancements such as defensive auras or active magical effects can be toggled if desired.

Time manipulation is not a supported function.

...hmm.

Preview: U[Spatial manipulation]

Preview: A[Spatial manipulation]

Spatial manipulation: Unlocks spellcrafting interface (0.1 points) Adds spatial manipulation components to spellcrafting interface, approximate cost 100 mana per 1% change and per 100 cubic meters of altered space per second, actual cost varies with specifics (0.5 points) Spatial curvature awareness (0.4 points)

There's a sound coming from behind her, it could just be the wind.

Hey look, a loophole.  Also, power, this certainly seems broken-ish - not to mention the subtler consequences it might have.  This was so stupid.  Why did she do it.

(...Excitement and overconfidence in her own cleverness, combined with the feeling that she needed to act now, rather than later, or risk dying (and losing all her stuff).)

Well.  Lesson learned, hopefully.

That sound is not the fucking wind; she would feel the wind, and she doesn't.

She falls into a practiced stance, and prepares for introductions.

Sound, meet Mr. Pointy Stick.

She feels her power start to engage but then pull back when something more urgent takes her focus.

That looks like a squirrel, more precisely three squirrels each of which is... maybe 8 times bigger than a normal squirrel. They're running at her at a pace that is appreciable even with the way the world is now slowed for her.

Oh, bother.

Alright.  Three targets, at speed; at least they're not smart enough to properly flank her.  Pull knife into off-hand, spear one, forcefully deflect two, stab three (with her knife, reverse-gripped).

She still isn't quite used to moving like this but she manages to get into her stance and get her spear in the way of the first squirrel. It's impaled blood splashes out of the wound towards her, it almost jars her spear out of her hands but she manages to keep a hold of it, it's a lot of weight to be holding up at the end of her spear though. The second one she's also able to push to the side with the haft of her spear it lands hard behind her but there's no time to think about that because the third is already leaping and if she wants to stab it like she planned she probably isn't going to be able to hold the spear up with just one hand.

Well, that's what the ground is for!  And also pulling the spear out of the murderous squirrel-alike; that'd work too.

She lets the tip of the spear and the now limp squirrel at the end of it fall to the ground, and brings her knife around to meet the third's leap. She manages to get the knife up in its path and with the reverse grip she's well braced but she doesn't seem to hit something vital with this stab like she did on the first and the squirrel's limbs claw at her arm, they shred through the leather but are stopped by the reinforcing panels.

Sheesh.  She's glad she thought to do that.

Step on dead squirrel for counterforce, pull spear and pivot, use momentum to fling wounded squirrel away, prepare for incoming squirrel 2!

The third squirrel flings away. The second squirrel is already leaping at her but as it's in the air something blurs towards it from further away and the squirrel explodes, showering her with viscera.
