I think we're on a "stage" and can expect to be buried under familiars.
Yeah, canon Homura only got attacked by familiars after she went through everything she had for her attack. Basically, she finished her part, so it was time to move to act 2. We've completed our act 1, so it's time for act 2.
If Wally spits out the dark stuff that turns into familiars, presumably sending a stream at each person up here, most are at risk of getting knocked off. We want to stay up here, right? So we need something to be sure people don't need another Homu-bail; can't be wasting seeds on that.
So we need something to anchor to. The best option we have for that is Kyouko's chains — spread out a latticework anchored to the gear that people can grab onto. We also need either the great shield or the sword block, preferably protecting as many people as possible.
Are there any other powers we can draw on here that are likely to help us? Really, we have very little in the way of defensive strength.
Will a Blade Block work if we can't embed the sword in the ground? Doing damage to the gears has been rather difficult, so I'm not sure that option is even possible here.
@TheOneMoiderah : Can we get confirmation on whether this is possible, mechanics-wise?
It popped upwards like it was spring-loaded.
We might possibly have open access to the spring area now? It's inside the gear, and was sealed in by the shaft. Is there any trick we can try?
/pours 15 tons of peanut butter inside the gear works...
