How to Beat Bilocyte

Attack the eyeballs on Levias Land on Levias' head Strike the projectile, hit the left and right fins Hit Bilocyte's eye

Attack the eyeballs on Levias' body

In order to help Levias, first attack with a Spiral Charge towards the eyeballs on the tentacles that grow from Levias. As Levias keeps moving, the distance can only be reduced bit by bit, so you need to be quite close when attacking.

Land on Levias' head

If you destroy all the tentacles, the parasite's body Bilocyte will appear on Levias' head. You can't attack this while riding the Loftwing, so land on Levias' head. Levias is still moving at this time, so fly as low as possible and dive.

Strike the projectile, hit the left and right fins

Once you're on his head, attack the left and right fins by striking the projectiles spit out by Bilocyte. Swing the sword to the right to hit the projectile to the right, and swing it to the left to hit it to the left.

Hit Bilocyte's eye

Destroying the left and right fins will leave Bilocyte vulnerable to attacks. You can deal damage when you hit his eye during this vulnerable state.

Another way of hitting his eye is by using your Bow or by using Skyward Strike.

Bilocyte's Attack Patterns

Body hit (Contact damage) Spitting

Body hit (Contact damage)

Move parallel to Levias

Levias does not attack, but if you hit his body, you will get damaged. Keep in mind that the tail part is big and moves around, so stay away from it.

Bilocyte Spits Projectiles

Hold your shield and flip it back with a sword

Bilocyte makes an attack that spits projectiles at you. You can attack and defend at the same time by striking it back to Bilocyte with a sword. If you are not confident, hold the shield as it will provide insurance if you make a mistake in the timing.
