[jk] "I reject this reality and substitute it with my own! Reality Marble: Puella Magi Rin Magica!"
This is getting nowhere, so I'll start it, I guess.
[x] Use Wand (Earth affinity) and gems to overpower the Gravity manipulation. Without wasting time getting up, use the moment of surprise to throw everything she has at those fakes. Rin Tohsaka will never again be at the mercy of monsters, even if it costs her life!
I have proclaimed my intention to make a suicide run, now I'm going for it. OoC, its a reasonable development, somewhat. She gets over her fear of monsters by accepting that even if she can't win, she won't lose if she chooses to do so. It might develop her resignation to oppose Shinji, of course, but whatever. Tohsaka's delusions and Shinji's idiocy in tandem have long since crossed my limit of patience on this issue.
Also, explosions are plain cathartic, you should always go for explosions if you have any choice.
