Update 18 significantly expands the endgame content of Anime Eternal, introducing a brand-new world for veteran players to conquer. The centerpiece of this update is World 22: Shadow Academy, a mysterious new area that brings fresh challenges, enemies, and rewards to the game.
Contents
The Shadow Academy represents the latest endgame content in Anime Eternal, designed specifically for players who have progressed through the previous 21 worlds. This new area features:
World 22 is particularly significant because it's an even-numbered world, which means players can farm Damage-type Shadows from SS-rank bosses here. This makes it an ideal location for players looking to optimize their damage output with the best Shadow equipment.
Update 18 introduces two powerful new gacha units that players can summon from the World 22 banner:
Shadow Garden
Shadow Arts
Both units are designed to complement the Shadow Academy theme and provide players with new options for their team compositions. To obtain these units, players must summon them specifically from the World 22 gacha banner – they cannot be obtained as random drops from stages.
One of the most significant additions in Update 18 is the Eminence System, a new progression mechanic that provides permanent character upgrades. This system introduces:
Eminence Coins
Eminence Progressions Players can spend Eminence Coins on four different upgrade categories:
This progression system provides long-term goals for veteran players and creates a meaningful reason to farm World 22 content repeatedly.

While we don't recommend spending Robux on gamepasses (farming Credits is more efficient), here's the ranking of the most valuable gamepasses in Anime Eternal:
The Shadows system, introduced in Update 16 Part 3, remains a crucial part of Anime Eternal's endgame content. With World 22 being an even-numbered world, it's an excellent place to farm Damage-type Shadows.
Shadows are guaranteed drops from SS-rank enemies found in Worlds 6 or higher. Here's what you need to know:
Damage-type Shadows
Energy-type Shadows
Located in World 6, these upgrades affect your overall Shadow experience:
This system lets you power up individual Shadows:
A: The most significant addition is World 22: Shadow Academy, which introduces a new area to farm, new enemies, and the entirely new Eminence progression system for permanent stat boosts.
A: You must summon for them on the gacha banner associated with World 22. They are not guaranteed drops from stages and can only be obtained through the gacha system.
A: Eminence Coins, dropped by enemies in World 22, are used to purchase four new upgrades: Eminence Energy, Damage, Luck, and a boost to Eminence Coin gain itself.
A: Look for the codes button in the main game menu (usually represented by a Twitter icon or a settings gear). Input the codes exactly as they appear in the list above.
A: Since World 22 is an even-numbered world, you'll get Damage-type Shadows. The best current Shadow is Koku SSJ from World 20, but World 22 may introduce new, more powerful Shadows.
A: We recommend focusing on Energy upgrades first, as Energy helps you rank up faster and increases damage indirectly. Once you have comfortable Energy generation, shift focus to Damage upgrades.
A: Farm Shadow Souls in World 6 or higher, then use them at the Shadow Upgrade Machine. It takes 48,600 Shadow Souls to max level a Shadow from 0 to 100.
A: Shadow Garden and Shadow Arts are designed to be powerful units that complement the Shadow Academy theme. If you're progressing through World 22 content, they're likely worth the investment.
A: Combine Eminence upgrades, Damage-type Shadows, optimal unit placement from our tier list, and use active codes for resource boosts. Focus on Energy generation first for faster ranking.
A: New codes are typically released during major updates, milestone celebrations (likes/favorites), and special events. Check our guide regularly or join the Discord for the latest code drops.
