Seen a lot of people talk about their solution to what happens when Friede does her weird vanishing move. A lot of people try to track her footsteps by ear, or just try to dodge the attack because of it's clear audio cue, but there's a way easier way that lets you know where she jumps to regardless of sound.

When she vanishes, she leaves a trail of frost behind. When she jumps, that trail moves with the force of her jump. So if you can't see her, but you see that frost cloud suddenly shift left, it means she jumped to the right. From there, because she basically won't move unless you come close enough to see her, it's as easy as walking in the direction she jumped. If you wait for her to begin her attack, you can get off a backstab as well. It makes her first form a cakewalk, and makes keeping track of her second form significantly easier.

it is zero help against the third form, god help you
