1. Start from the middle and jump to the platform on the side. On the side platform, she will fire cannonballs, which can be dodged as long as the player doesn't pull directly towards her. It is recommended that players use a path where they can frequently jump from one side to the other. It would be even better if you could grab the super jump and use it to jump right over her projectiles.
2. The attack sequence is always the same. If the player fails or dies, it will be the same in every stage. Therefore, just click-click-pause-click-click, and the opponent's attacks are cyclical. Parrying will cause the player to take a few steps back, so just pay attention to being on the edge of the platform to avoid falling.
The above is the entire content of the Ghost Walker Hel strategy guide, I hope it will be helpful to you.
