2:10 - Bash Invincibility

4:47 - Walk Under Water Glitch
5:27 - Feather Jumps
6:33 - Wavedash
7:16 - Grenade Bash
7:54 - Conclusion

Corrections
There is a 2 frame window for Grounded Sentry Jumps and a 1 Frame window for Midair Sentry Jumps when using Spirit edge
Feather jumps can also be performed by falling off of a platform while holding feather and it can be stored in water by entering and leaving it with swim dash. Also, for doing it with burrow and swim dash you need to be in a grounded state or have a feather jump stored when you use the ability for the feather jump to be stored.
Having Spike makes it so you can no longer do Bash Invincibility.
If you can't seem to pull off some of these tricks it might be because of your framerate. Keep it capped at 60fps to make all of them more consistent.
