| How to Complete | |
|---|---|
| 1 | From Hyrule Castle, head northwest until you reach a waypoint that leads to a forest with blue fog. |
| 2 | Once you enter the Eternal Forest, the minimap becomes unusual. Head to the right side first to reach a dead end then head back and turn left to find 3 guards in front of a headstone. |
| 3 | After the cutscene ends, inspect the gravestone. This causes the gravestone to rise up, spawns a floating orb on the left side, and activates The Prime Energy and Null main quest. Use the Tri Rod on the orb to learn the Ancient-Orb Echo.
▶︎ Rescuing the Hero Link Walkthrough |
| How to Complete | |
|---|---|
| 1 | After rescuing Link, talk to him to give his weapons back. Tri asks another confirmation if you want to enter the rift inside as this is a point of no return. Select "I'm ready". |
| 2 | Follow Link and enter the door on the north until you reach a room that will spawn enemies. Defeat all the enemies to open the locked doors. |
| 3 | Enter the door on the right. Use a Flying Tile Echo to break the purple ball on the right side to unlock both doors for you and Link to enter. |
| 4 | Defeat all the enemies in the next room. Spawn a group of Boomerang Moblins to distract the group of enemies in your area and wait until Link defeats the enemies for you. |
| 5 | Use Reverse Bond on the moving platforms to reach the next area. Spawn a Wizzrobe to push the purple orb down to the bottomless pit. |
| 5 | Use the Keese Echo to jump on the geysers and wait for the purple orb to burst out to glide towards the ledge on the left side. Use the Old Bed as a staircase to reach the ladder that leads to the top. |
| 6 | Enter the room on the right and help Link reach the pressure plate on the opposite side. Place two Old Beds that are stacked on top on of each other and use Bind on Link to place him on the same elevation as the tall ledge on the right. |
| 7 | Follow Link as you head north of the area. Jump down to the pit and watch the cutscene that follows. |
| How to Complete | |
|---|---|
| 1 | Spawn a group of enemies such as multiple Boomerang Moblins to distract Null. This allows Link to target the glowing red weakpoints on its arms and put it on a stunned state once all of its arms are gone. |
| 2 | Null will flee after and its arms will start to appear on the walls. Use Bind to extend the arms, allowing your Echoes and Link to attack the glowing red weakpoints. Once Null reappearrs, use Bind to extend its arms to cut them down. The boss will repeat this attack pattern until a cutscene plays, putting you to the next phase of the fight. |
| 3 | The next phase of the fight has you battle Null in a sidescroller format. Use Bind to extend Null's arm to expose its weakpoint and summon two Chompfish Echoes to help you out. Make sure to swim forward and towards the bubbles to regain your air meter and avoid the tornadoes. You can equip the Zora's Flippers or drink Swim Up Smoothies to swim faster during this phase. |
| 4 | After finishing the previous phase of the fight, you will reunite with Link and battle Null on a topdown format. Summon multiple Boomerang Moblins to help out Link and use Bind to extend Null's arms. The boss periodically changes forms to imitate the previous bosses's attack patterns. When this happens, avoid its attacks and respawn the Boomerang Moblins that despawned. |
| 5 | After cutting down all of Null's arms, it will flee and spawn arms from the walls and the floor. Use Bind to extend the arms and have Link and the Boomerang Moblins swarm and attack it. Make sure to move around when Binding as some of its arms may emerge from the floor to attack. |
| 6 | Null will remerge once again and will attack by imitating Ganon's attack patterns. Use the same boss strategy by Binding its arms and allowing your Echoes and Link to attack it until all of the arms are gone. |
| 7 | The boss will start to repeat the same attack pattern where its arms will appear on the walls. After defeating the arms, the boss will emerge and will use the Gohma's attack patterns. Use an Echo that generates fire to burn down the spider webs that it leaves on the floor. Follow the same strategy of using Bind to extend its arms. |
| 8 | Once the Primal Energy appears from Null's core, use Bind to pull it to initiate a cutscene. Tap the A Button repeatedly to pull it from its core, defeating the final boss. |
This refers to the first and last phase of the boss fight where you fight Null from a topdown perspective. Link will accompany you in these phases of the fight.
During the topdown part of the boss fight, spawn multiple Boomerang Moblin Echoes to keep Null distract in order for Link and the other Echoes to attack the glowing red weakpoints.
Once the boss is targeting Link and your Echoes, use Bind to extend one of its arms to allow them to cut it down. Repeat this step for all arms in order for the boss to enter in its weakened state.
During the last phase of the boss fight, Null will periodically transform into the Gohma to release spider webs on the floor. Use an Echo that generates fire such as the Fire Wizzrobe or the Torch Slug to burn down these spider webs.
This refers to the second phase of the fight where you fight Null in a 2D sidescroller format while swimming. You only have your Echoes to assist you in this phase.
It is recommended to use two Chompfish Echoes to attack Null's weakpoint in this phase of the fight. This Echo swims fast and attacks relentlessly, giving you some time to swim around to avoid the environmental hazards such as the tornadoes.
Once you have the boss distracted with your two Chompfish Echoes, use Bind to extend its arms and expose its weakpoint. Your Echoes will automatically target the weakpoint. Repeat this step for all of its arms.
Your air meter depletes over time during this phase of the fight, so you will need to swim towards any air bubbles that will appear to restore them.
The phase of this fight has you swimming while fighting the boss so it is recommended to equip the Zora's Flippers and drink Swim Up Smoothies to increase your swimming movement speed.
This comes in handy as you will need to manage your air meter and fight the boss at the same time.
The Prime Energy and Null main quest is located at the Eternal Forest.
The Prime Energy and Null is the last main quest of Zelda: Echoes of Wisdom. Completing it shows you the ending scene and the credits roll.
Once the credits roll ends, you can resume the game from the last save point and complete any side quests that you have left behind.
