The Legend Of Zelda: Tears of The Kingdom offers Link many weapons and armor to use in his journey across Hyrule. Many of these gear are legacy armor pieces, allowing Link to wear costumes from his previous games or to dress like iconic characters throughout the series.
One of the legacy armor pieces is Ravio's Hood, which can be found by exploring the depths and fighting in a coliseum. Ravio's Hood increases Link's ability to climb sideways and use less Stamina for those looking to do far climbs, even with limited stamina upgrades.
Getting To The Secluded Coliseum
The Secluded Coliseum is located in the darks of the depths. To enter the depths, you'll need to start from Kakariko Village. Go to the northeast to the entrance to the depths and drop below. Be sure to bring many Brightbloom seeds to light your way to the arena. There are no Lightroots along the way, so pick and choose fight carefully to make sure you don't lose hearts before reaching the Coliseum. Head to the west to reach the Abandoned Kakariko Mine. After clearing the mine, climb the large mountain to the south.
From the top of the mountain, launch brightbloom seeds from your bow further south to see the Coliseum below. The Coliseum's coordinates are 2239, -1908, -0468. Drop down to the outside of the Coliseum, going in through the front gate. Before walking into the main area, be sure to launch more Brightbloom seeds throughout the area to light the area if needed. When ready, approach the chest to trigger the Coliseum.
Fighting In The Secluded Coliseum
The Secluded Coliseum will be five back-to-back waves of gloom-powered enemies that you'll need to beat to unlock the chest. The first wave will be two gloom fire-breath Lizalfos; the second wave will be two gloom ice-breath Lizalfos, and the third wave will be two gloom electric Lizalfos.
For the most part, these three waves are similar, with the melee attacks being the same. The fourth wave is a gloomy silver Lizalfos, being much stronger and dealing a large amount of damage with its slow wind-up attacks. The fifth and final wave will be one of each gloom Lizalfos, with the Silver Lizalfos being the strongest.
Utilize bomb-fused arrows to hurt all four enemies at once, stunning them and making them drop their weapons. This will give you brief control of the battlefield to prepare for the charging enemies. After defeating all five waves, the chest in the center of the Coliseum will be openable, with Ravio's Hood inside. While this helmet is equipped, the Stamina used when climbing horizontally will be decreased.
