How to complete the Blocked Well in Zelda: Tears of the Kingdom
In this side adventure, you will find out that a long time ago Princess Zelda forced the stable to shut down. The reasons were unknown.
Years later this stable has become a topic of discussion and as a reporter, you must find out why it was shut down.
Drop down into the well
Start off by dropping into the well and swim your way to the Brightcap sticking out of the rock on the left. Collect the Brightcap and find a blocked wall on the right.
Break the blocked wall
Break this wall down using a heavy weapon from your inventory. A hammer is always the best thing to use in these situations.
In the process, you may damage your weapon but at least you can acquire the Opal behind them.
Defeat the Lizalfos
Opals aren’t the only surprise you receive after breaking the wall. You will also encounter three Lizalfos. Although keeping a safe distance is required in these situations, doing so will result in you receiving a spitting attack from the monsters.
Therefore, start off by dealing with the archer and then the other monsters that wield a melee weapon. As you kill the monsters, they will drop 1x Black Lizalfos Horn, 1x Lizalfos Talon, 1x Blue Lizalfos Horn and 1x Blue Lizalfos Tail.
Defeat the Like Like
After defeating the three Lizalfos, you will have to deal with the large Like Like spawning from the top. Simply shoot a bow at the large ball in its mouth.
After defeating it, it will drop a chest for you to loot. Looting the chest will net you 1x Gerudo Claymore. You can also collect the Steal Lizal Shield next to the chest.
Defeat the Electric Lizalfos
Make your way out of the cave from where you fought the Like Like and fight the Electric Lizalfos in your way.
Kill it using your bow and trigger a conversation with Penn to receive 1x Purple Rupee and 1x Lucky Clover Gazette Fabric. This will complete the Blocked Well in Zelda: TotK.
