Mythos adds myth-themed boss fights, structures and gear from two mythologies, with more to come.
Turkic realm. Find Tulpar, Asena, Tepegöz, Al Karısı, Yelbeğen, Abra, Arçura and Şahmaran in their own lairs.
Greek realm. Challenge Zeus, Hera, Poseidon, Hades, Athena, Apollon and Aphrodite in their temples.
- Bosses: Each of the 15 bosses has eight custom-animated attacks, its own battle theme and a death fanfare. Each also has a weakness and a special finishing condition you have to work out.
- Structures: Every boss waits in its own structure, and roads and camps lead up to it.
- Minions: Each boss comes with its own kind of guard creature.
- Loot: Bosses drop materials, hearts, weapons, charms, potions and full armor sets with set bonuses. Hearts craft into powerful cores, and each realm ends in a transcendent final weapon and talisman.
- Item abilities: Weapons, staffs and talismans have active powers on cooldowns, such as calling lightning, tidal waves, curses, arrow barrages and charming enemies.
