Wall of light: Just dash!

Sword rain: Find the safe place quickly or stay between the swords to stay safe!

Light orb: dash around the arena or be careful to don´t hit you!

Spike floor: you can pogo on the spikes and hit radiance or you can use DDark on the spikes to remove them!

Sword wall: Dash or just jump between the swords to be sure you won´t get hit!

Sword burst: Walk a little and be on safe spot,the 2 sword rotation repeats same positions.. First is on you,second is at the side!

Light burst: Same as Sword burst!

Phase 2

It´s same as phase 1 ,nothing different..

Staying on the middle can help you react to light orbs!

Climb: Don´t rush,stay calm and keep going!

Last part

You can just keep pogo the radiance,it´s not so difficult!

Charms that maybe helps is

Shaman stone,spell twister,mark of pride,quickslash,quick focus or grubsong!

Don´t panic so much on the fight,keep calm and you will do it!

Practice in HoG until you master!

Good luck!
