Alright, I'll throw some 214C FC knowledge your way Chie players! Well, first off, the Narukami thing I was talking about is just that: punish Narukami DP in the corner at the peak of his DP with 214C, it'll fatal and since he's so high up you'll have enough time to just dash up off the fatal and do the 5B > 5C > 2D etc etc normal 214C fatal combo meterless. You can select to end with 5A+B instead of the super ender if you want, since the combo itself builds about 45% and this will give you great oki since normally this will mean the next hit will kill due to comboing into God's Hand. Technically, you can hit Aigis's DP with this too, but this is rather hard and unlike Narukami's it doesn't ensure you'll be super cancel safe.
You can also SMP with this, and it can do a ton of damage if you're already sitting on about 30% meter and a burst. 214C against Narukami/Aigis DP (or jump back buttons, since people love doing this vs Chie too), dash 5B > 5C > 2D > j.BB > dj.C > OMB > (slight delay) 236236D > 2A > [5C > 236B > 236B] x3 > 5C > 236B > 236A > 214C (You can omit the 214C and just go into another God's Hand if you have it). You can do AOA after the second Rampage Skull Cracker too if you want tons of damage AND knockdown, although this will probably put them into awakening and I don't see much of a use for this over just going for damage because of that considering the resources you've already put into that combo anyway.
First time really posting combos and stuff, so I hope this is all somewhat clear.
Edit: I forgot something, oops. The anti-Narukami DP punish timing changes a bit on instant block, you have to walk back a small tick in order to get it, or he'll cross you up, land and probably punish you. Just something to be aware of.
