Personally, I'd like to keep advocating for a more personal wish than a wish that's trying to game the system, despite knowing I probably can't convince SV.
The reason we are becoming a magical girl in the first place is a result of the desire our Incubator self shows - to leave behind the limits of it's emotion-ridden human self and rejoin the collective. So I think a wish born from our more human side (perhaps with the self-delusion that it's "so we can better understand humanity through knowing the full scope of their experiences first-hand") is something more narratively interesting than whatever powers we can gain from a wish. I'd much rather a simple "I wish my mom was still alive," maybe even slightly optimized so she doesn't just appear out of the blue and leave everyone confused about how the dead have come back.
Hmm
Honestly, I agree that we probably shouldn't try to optimize too hard. Character matters more, after all.
Plus, the GM *did* say that system breaks tend to either fail or result in certain doom- or, more likely, are simply never considered.
So there's little point in trying to optimize. The rewards will be offset by the cost, after all.
I'd also say that we should think in-character . . . But the issue with that is that Rachel would try to optimize, despite the issues. She's part Incubator, after all.
So, trying to optimize is actually in-character.
Therefore . . . What would she do?
Well, she wants to survive. The longer she lasts the more likely that Kuybey will re-integrate her. I doubt she cares about getting new friends. She doesn't particularly care about her body- or even really herself. She knows all the rules to this game. And she *really* wants to be an Incubator again. She hates that she had to feel things.
. . .
Honestly, wishing to just feel nothing ever again is a really in-character thing for her to do. But the issue with that is it'll kinda contradict the premise of this quest, as well as going against the wish that got Rachel into this situation in the first place. Plus, I don't really want to play as an emotionless husk.
So . . .
She doesn't really care for herself. Or, at the very least, she tells herself she doesn't. So I think she'd be fine with a machosistic wish, if that could give her more power.
[ ] Wish to maximize your own potential, and by extension your strength.
[ ] Write in
On the wish front: Personally, I don't think the former would be fun. It'll be generally useful, but it would kinda max ourselves out. This also implies that we wouldn't need to experiment with our powers, because our potential would be maximized. So no need for Science! sessions.
This would be a tragedy.
So, relating back to what I was saying before, here's my vote:
[X] I Wish for my soul gem to the indestructible and incorruptible. This means that it cannot be destroyed or tainted. However, I know that magic has its costs. I don't have enough potential to negate them. So, in addition I wish for whatever costs I need to accomplish this, both natural and the excess that is no doubt required, be paid to me NOW so that I can achieve my impossible desires!
Here's my reasoning:
It's an attempted system-break by Rachel, something that she would definitely do to boost her power because of her Incubator mindset.
It doesn't negate the cost of the wish, which means that, according to my understanding of Madoka Karmic Balance, we should be able to do it.
Most people wouldn't, when given the opportunity to wish for anything, specifically wish to cause harm on themself. However, Rachel doesn't really care about herself. So as long as this is able to boost her power, she'll consider it.
It's efficient. Normally, the cost would be spread out and monotonous. It'll interfere for a long time. But with this? It'll be over with very quickly.
The reward, basically immortality, is too good to pass up. Who cares if the cost is steep? Who cares if your mere *vessel* has to endure a moment of hell?
Additionally, this is going to give us a bizarre powerset for us to play with. We'll get to have so many wacky Science! sessions.
Finally, if worst comes to worst, the GM can undo things by a few minutes and we can choose a saner option.
Edit:
Also, if the soul combustion is loud enough then it'll attract the notice of our friends, which means an extremely probable contract! We'll take our first steps so quickly!
Edit:
In case you couldn't tell, a major draw of this wish is that it is a tremendously bad idea that seems reasonable on the surface. It seems, to me at least, that Rachel could do this or something like it. Would she regret it? Definitely. Especially in that NOW. But this entire contract is a mistake regardless, so might as well make it a unique and horrific one!
