The Immortals Fenyx Rising mythical boss locations contain some of the hardest fights in the entire game. And not only are they tough battles, but they also lead to new armor and the “Who’s the Boss?” trophy or achievement. Here’s how to find all of the mythical monster bosses in Immortals Fenyx Rising. Just be warned as these are all very tough fights and can demolish players who don’t have a lot of health or stamina or low-level weapons and gear.
Immortals Fenyx Rising Mythical Monster Boss Locations | Ozomene | Valley of Eternal Spring
Ozomene isn’t too tough to find because Athena gives the player a mission to fight her. Ozomene is located west of the Valley of the Eternal Spring on an island.
The island is notable because there is a big cyclone at the top that is visible from a distance.
Get to the exact spot on the above map and a cutscene will play once Fenyx steps into the arena.
Immortals Fenyx Rising Mythical Monster Boss Locations | Medusa| Grove of Kleos
Medusa is also not hard to find as she, like Ozomene, is also on an island to the northwest of the Grove of Kleos.
The island is covered in fog and dead trees, which is a lot like Medusa’s forest in Assassin’s Creed Odyssey.
Once the player makes their way to the center, there will be an arena where Medusa will come out.
Immortals Fenyx Rising Mythical Monster Boss Locations | Polyphemos| The Forgelands
Polyphemos is also on his own island, but this one is a little more out of the way. His island is on the northeast side of the Forgelands in the big colosseum-like arena.
Glide toward the arena. It has purple crystals floating over it.
Once Fenyx gets into the arena, Polyphemos will emerge and be ready to fight.
Immortals Fenyx Rising Mythical Monster Boss Locations | Kottos | War’s Den
Kottos is perhaps the most difficult to find as he doesn’t have his own island, unlike the other three. However, it is possible to hear some beast in the War’s Den area. Kottos is at the top of Ajax’s Fort, which Fenyx travels in during Ares’ campaign.
Climb all the way to the top near the glitter and Fenyx will make a comment.
The beast will then surprise the player and start the battle once they climb to the very top.
