After you obtain the Falling Star, you can enter the Black Tower and face Veran.
The Black Tower
When you're ready, go to the Past, then go to the southwest corner of Lynna Village, where you can enter the Black Tower. There will be a cutscene.
Continue to the entrance of the Tower. Go east from the worker (the north path just leads to a dead end full of Ropes) and continue around the path, fighting monsters such as Gels, Blue Octoroks, Tektites, and Pig Warriors, to reach the stairs to the level above.
On the next level you will find Shrouded Stalfos, Beamos, Gibdos, Like Likes, and Red Darknuts on the way to the next set of stairs.
Above that, there are Red Darknuts, Blue Darknuts, Green Wizzrobes, Blue Darknuts, and Red Wizzrobes.
In the next room, there are three doors. There will be a cutscene. In a Linked Game, there will be a second cutscene. Go through the door to enter the Black Tower Turret.
Black Tower Turret
This is a maze of staircases. There are Wizzrobes and Darknuts throughout the area. You may need to use bombs to get rid of the Darknuts. To get past the maze, do the following:
- Go up the stairs in the middle of the left wall.
- Go north and use the stairs.
- Use the northwest stairs.
- Go south and use the first set of stairs you pass.
- Go east, ignoring the first set of stairs you pass, then go north and use the stairs at the end of the path.
- Use the stairs to the south.
- Use the stairs in the middle of the north wall.
- Go south and use the stairs.
You will arrive in a room full of staircases. Wait for the flames to move out of the way before proceeding. In this room full of staircases, only one of them goes to the correct place. The correct stairs are to the left of the southeasternmost stairs.
Upstairs, the pots may contain fairies, so be sure to collect those, then go north and use the stairs.
You find yourself in a large area with many enemies around. Your destination is directly north from where you are, but you must first go south. Then you can either go east, then north, or west, then north. Whichever way you go, you'll encounter Blue Lynels, then a Ball and Chain soldier. Get past those enemies, then go to the door in the middle of the north wall.
There will be a cutscene. Go north to start the final battle!
Possessed Ambi Form
This battle is very similar to the one that you fought against the possessed Nayru, but Ambi moves more quickly and shoots more fireballs. She can also send spiders to attack you. Shoot Mystery Seeds at Ambi to separate Veran from her body, then use the Long Hook to pull Veran away. Hit Veran with your sword. After you defeat this form of Veran, there will be a cutscene.
Next, Veran turns into a fairy-like creature and creates four Dark Links. Just hit Veran if she comes near you. She will sometimes fly across the room and spit blue orbs at you. She will sometimes stop and create a large orb that spits smaller orbs in a spiral. The Dark Links move in the opposite direction from you, just like Arm-Mimics. You can defeat them more easily if you go to a corner to make them all go to the same spot, then go toward the middle of the room and attack them all at once. They drop recovery hearts.
When Fairy Veran is defeated, there will be a cutscene.
Veran Phase 2
In this stage of battle, Veran will switch between forms.
She will jump up and try to crush you. Stay away from the area below her to avoid damage. When she reveals her face, hit her repeatedly with your sword.
Avoid the webs that Veran shoots at you. She will sometimes run more quickly toward you. She will sometimes jump into the air, then crash down. Throw bombs at her (Bombchus don't work) to make her show her face. Hit her when her face is visible.
Just hit her when she flies near, or use the Seed Shooter to hit her from a distance. She may go from one side of the room to the other while shooting stingers downward. You can stand between the paths of the stingers to avoid this. She might send smaller bees at you, which you can kill to obtain recovery hearts.
If you're playing a Linked Game, after the cutscene, you will be healed up, then sent to the Room of Rites. You can optionally use the portal where you arrived to go back to the Maku Tree. You can use the portal to return to the Room of Rites when you're ready.
Congratulations! Enjoy the credits, and if you're not playing a Linked Game, be sure to make a note of the Secret to Holodrum password shown at the end so you can start a Linked Game of Oracle of Seasons!
