DST Clockwork Bishop (CB) + Double CB Setpiece No Damage Methods

One thing that's worth mentioning is the fact that every method that I've shown here can be used as ANY character in the game. Obviously some are harder than others, but they have their own advantages so it's up to you which one do you pick.
Feel free to speed video up or to skip to desired method. Next to each timestamp I'll put some kind of label to let you know if shown method is the one I recommend or not (also if it's pointless or not).
I don't mind if you too rate shown methods yourself. In fact, I would like to know your opinions on these methods, which ones do you prefer and why.
Recommendation is rated from 1 to 5 as follows:
1. Not recommended under any occasion/Pointless (NR / P)
2. Not recommended but can be used in certain cases
3. Situational
4. Recommended in certain cases
5. Highly recommended
In case I rate method as 3 It's up to you to decide if it's worth it or not but other than that every other rating I give is based on my opinion.
