I’m sure enough people have been sitting on this technology for a while, but I’ve never seen it talked about, so here goes.
Sentinel has instant overheads on a large part of the cast. These overheads are possible because of fuzzy guard. I’m not exactly sure who they don’t work on, but as a reference point, they do work on Chris and they don’t work on Morrigan.
Check out this ultra-HD video I made:
Here’s what’s going on:
In the first section of the video, I show what happens if you do instant jump-back H against a crouching Chris – it whiffs. Neutral jump instant L also whiffs, although I didn’t show that.
This second section of the video demonstrates what happens if you do a deep-ish j.H, Chris crouches expecting c.M, and you do instant jump-back H – it hits! If you use an assist with your jump-back H, you can turn this instant overhead into a big combo. Here I use Tron, but there are a shitload of options.
In the final section of the video, I show the real tricky shit. While instant jump-back H is an “instant” overhead, it’s not all that instant. However, j.L is hella instant and is also able to take advantage of fuzzy guard. Here I do deep-ish j.H ~ assist, Chris blocks low expecting c.M, but I do instant j.L (which hits) and continue from there. Again, you don’t need Tron, but you do need an assist.
Hope this helps. Any questions, feel free.
