In The Legend of Zelda: Breath of the Wild, you can refer to the following for the high-level fire fighting method of Zelda's Trial of Power:
first step
Place the firewood under the guardian.
Step 2
Slash with the flaming sword. If the guardian doesn't move, it will be considered a success.
Step 3
Go behind the pillar to hide from the laser cannon, or you can use the laser cannon in an open area to practice Link's timing and shield reflexes, waiting for the guardian to be roasted to death.
