Thank you!. The two biggest parts of windbombing is that you
1: make sure the round bomb is out before you in to bullet time I think items act differently depending on if they were there before or after entering bullet time
2: pretty quickly, you need to press B to stop aiming your bow. If you dont, it wont work
I saw a video showing the basic button sequence of doing a windbomb. And it's best to hold ZL to focus cause that really helps.
Here's the sequence
ZL, Ls up, X, L, Zr, D-pad up, change to second bomb, L, switch to first, L
Hope this helps in any way 😁
