SECRET BOSS LOCATION in ANIME ETERNAL: Complete Shadow Fighter Farming Guide

Hey everyone! Today I'm breaking down all the SECRET BOSS LOCATION in ANIME ETERNAL where you can farm those elusive Shadow Fighters. If you've been struggling to find where these powerful SS-rank bosses spawn, you've come to the right place. I'll show you exactly where to look and how to maximize your farming efficiency.
The SECRET BOSS LOCATION in ANIME ETERNAL starts from World 6 onward, where all SS-rank NPCs have a chance to drop Shadow Souls. There are currently two types of shadows in the game - DPS damage shadows and energy shadows. These shadows are game-changers because they're the first fighters that can actually help you in battle, significantly boosting your damage output. The mechanic is fantastic, though their reaction time is slightly shorter than regular fighters.
Where to Find Shadow Bosses Starting from World 6

The SECRET BOSS LOCATION in ANIME ETERNAL begins at World 6, and this is crucial - shadows ONLY drop from SS-rank bosses starting from this world onward. Don't waste time farming earlier worlds thinking you'll get shadows, because it won't happen. The drop system is specifically designed for worlds 6 through 20.
Here's what you need to know about the farming process:
Only SS-rank bosses drop Shadow Souls (not S-rank or lower)
Higher world bosses have better drop percentages
Energy shadows and DPS shadows alternate between worlds
You need to delete lower-rarity drops to focus on SS-rank items
The key is to farm areas with multiple NPCs clustered together, even if individual drop rates are lower. More enemies mean more chances overall.
Best Farming Spots and Drop Rates Explained
When looking for the SECRET BOSS in ANIME ETERNAL, you'll want to prioritize areas with the highest concentration of SS-rank bosses. While some isolated bosses have higher individual drop rates, clustered areas often yield better results over time.
Here are the drop rate progressions as you advance:
World 6: First DPS shadow (Statuette boss)
World 7: First energy shadow (Crow boss) - 3% drop rate
World 9: Energy shadow - 6% drop rate
World 11: DPS shadow - 12% drop rate
World 19: Best energy shadow - 21% drop rate
World 20: Best DPS shadow - 24% drop rate
The percentage increases by approximately 3% with each new world, making later worlds significantly more efficient for farming.
Shadow Evolution and Upgrade Systems
Once you've found the SECRET BOSS and collected enough Shadow Souls, you'll need to understand the evolution system. Shadows can be upgraded using special machines and resources you'll find throughout the worlds.
Key upgrade systems include:
Shadow Evolution Machine (increases soul drop rates)
Shadow Upgrade Machine (enhances shadow abilities)
Credit system for extra shadow equipment slots
Token burning for additional upgrades
The maximum shadow level is currently 100, and you'll need to farm substantial tokens to fully evolve your shadows. I recommend focusing on energy shadows first since they help you progress through maps faster.
Pro Tips for Efficient Shadow Farming
Based on my experience with the SECRET BOSS LOCATION in ANIME ETERNAL, here are some essential tips:
First, always complete Obelisk quests - they're bugged but incredibly rewarding for energy damage and XP gains. Second, make sure to collect daily potions, especially if you have premium game passes for bonus resources.
Additional recommendations:
Focus on mythical rarity NPCs for better drop clusters
Save your machine tokens for important upgrades
Delete lower-rarity items to keep your inventory clean
Prioritize energy shadows early for faster progression
Remember that shadows are account-bound on Eternal accounts, so you can't trade or help others with them. The system is designed for personal progression through strategic farming.
