After successfully defending the gates for a period, a powerful Hollow will appear. This enemy is a formidable foe. The Hollow has a wide range of attacks, including powerful slams and energy blasts. Use Impa's speed to get behind it and unleash combos. Her clones will help deplete its Weak-Point Gauge quickly. When it charges up a large attack, use a Sheikah Slate Rune (like Stasis) to interrupt it and create an opening.
If you're struggling with Impa, switch to Link and use his more direct combat style. Focus on dodging its attacks and landing heavy blows. The Hollow's Weak-Point Gauge will appear after certain attacks or when stunned. Deplete it for a Weak-Point Smash. This battle is a test of your ability to manage multiple characters and exploit enemy weaknesses under pressure.
