Nail Bouncing & Pogoing
Hitting an enemy or certain objects (like spikes or certain projectiles) from above with your Nail will cause the Knight to bounce upwards, resetting your jump. This 'Nail bounce' or 'pogo' is crucial for traversing spike pits, reaching high platforms, and staying airborne during boss fights. Master this technique to avoid ground hazards and extend your attack combos.

Dash Canceling & Invincibility Frames
The Mothwing Cloak and Shade Cloak provide invincibility frames (i-frames) during the dash. Timing these dashes perfectly allows you to pass through enemy attacks or even entire enemies without taking damage. This is vital for many boss fights. Desolate Dive/Descending Dark also grants i-frames during its animation, making it a powerful defensive and offensive tool.
