Breath of the Wild
The Coliseum Ruins were once an arena used for combat, but like much of Hyrule, they have fallen into despair. They are now filled with strong monsters. There are numerous Black Bokoblins, Black Lizalfos, Black Moblins, and a Lynel that infest the area.
Just outside of the Coliseum Ruins to the south, near the Aquame Bridge, a Hylian named Dai can be found. He wants to enter the Coliseum to fight the enemies, winning their weapons and some treasure. However, he cannot quite bring himself to do it and instead just stands outside, trembling in fear.
A treasure chest can be found at the very top of the Coliseum at the far north end, which contains five Bomb Arrows. A second treasure chest can be found at the top of the ruins at the south end, with this one containing an Amber gem.
The enemies at the Coliseum Ruins will vary in which equipment they hold, depending on how many Divine Beasts Link has defeated. At the center of the Coliseum on the ground floor, Link will encounter a Lynel. On the second floor, there are three Black Bokoblins. There are three Black Lizalfos on the third level and three Black Moblins on the fourth floor.
Zero or One Divine Beasts
If Link has not defeated a Divine Beast, or if he has only defeated one of them, all enemies in the Coliseum will carry weapons from the Hylia Series Soldier class.
For each of the three types of enemies on the upper floors, one of the variants will carry a Soldier's Spear. Another one of the variants will have a Soldier's Claymore. Then one of the variants will have a Soldier's Broadsword and a Soldier's Shield. So if Link defeats all three Bokoblin, he can acquire all four items in the Soldier class of weapons. Defeating all the Lizalfos, will give him a second set of those same weapons.
Two Divine Beasts
After Link has defeated two Divine Beasts, increasing the World Level, all of the enemies in the Coliseum will receive an upgrade. Instead of the Soldier class, all enemies will be upgraded and will now carry items from the Knight class. This includes a Knight's Halberd, Knight's Claymore, Knight's Broadsword, and a Knight's Shield.
Three Divine Beasts
After Link has defeated three Divine Beasts, all of the enemies in the Coliseum will now carry items in the Royal class. This includes a Royal Halberd, Royal Claymore, Royal Broadsword, and a Royal Shield.
All Four Divine Beasts
After Link has defeated all four Divine Beasts, all of the enemies in the Coliseum will now begin to carry elemental weapons. The three Black Bokoblins will carry a Flameblade, Great Flameblade, and a Flamespear. The three Black Lizalfos will carry a Frostblade, Great Frostblade, and a Frostspear. The three Black Moblins will carry a Thunderblade, Great Thunderblade, and a Thunderspear.
When playing in Master Mode, there will be Silver Bokoblin, Silver Lizalfos, and Silver Moblin as the base enemies, all wielding the aforementioned weapons depending on the number of Divine Beasts cleared. Furthermore, the Coliseum will begin with a Blue-Maned Lynel. After all Divine Beasts are defeated, a rare Golden Lynel will appear.
EX Treasure: Phantasma
- Main article: EX Treasure: Phantasma
As part of the EX Treasure: Phantasma side quest, Link can find the Phantom Helmet at the Coliseum Ruins. This chest only appears if The Master Trials DLC is loaded into the game file. Misko's EX Journal will point Link to a battleground, where brave souls tested their skill. The treasure chest with the armor can be found on the ground floor, at the northwest end of the ruins. Use Magnesis to easily spot the treasure chest.

While gradually climbing in elevation. Link can use Ultrahand on the Korok and once high enough, move him to safer ground. After reuniting the two Koroks, Link will earn a pair of Korok Seeds.
- Just east of the Coliseum Ruins, there is a small pond. Hit the Dandeleon here and catch it before it hits the ground to get the Korok Seed.
Bugs and Materials
- The Coliseum is surprisingly close to the Great Plateau, too close for comfort for a location with such threatening enemies. Should the player not follow the Seek Out Impa prompt to head to Kakariko Village, there's a considerable possibility that they'll find the Coliseum just after finishing the tutorial area, all while being both underequipped and unarmored.
- The Coliseum is the closest area to the Great Plateau that is blighted with Malice. Said Malice cannot be removed, as there are no eyeballs to shoot. It's also the closest area to the plateau featuring a Lynel and Lizalfos.
