Secret bosses in Anime Celestial X sit off the main paths, hit a lot harder than standard encounters, and pay out far more Yen and unique artefacts. Each of the first four worlds hides one of these fights, plus a World Line Giver NPC that hands out a dedicated quest so your kills actually count.
You can reach every secret boss with basic movement: double jump and dash are enough, and mounts or flying tools like Nimbus are optional quality-of-life, not requirements.
Secret bosses overview and artefact drops
Each world contains one secret boss with significantly inflated health and a small loot table focused on Yen and artefacts. Artefacts are accessory-style items that increase damage, survivability, movement, or other stats. Secret bosses are currently the only way to obtain them, and each boss can drop two different artefacts with low drop rates.
| World | Secret boss | HP | Max Yen | Artefacts and rates |
|---|---|---|---|---|
| World 1 – Namek | Broky | 1M HP | Up to 54K Yen | Frizo Artefact (0.10%), Broky Artefact (0.01%) |
| World 2 – Shinobi Village | Madera | 3M HP | Up to 125K Yen | Madera Artefact (0.01%), Agony Artefact (0.10%) |
| World 3 – Hunters Domain | Miruem | 10M HP | Up to 400K Yen | Chrullu Artefact (0.10%), Miruem Artefact (0.01%) |
| World 4 – Desert Kings | Flamingo | 50M HP | Up to 3M Yen | Shanks Artefact (0.10%), Doflamingo Artefact (0.01%) |
Higher worlds scale up both HP and Yen, while keeping the same pattern of one “rare” artefact at 0.10 percent and one “ultra rare” at 0.01 percent. If you are targeting artefacts specifically, expect extended farming sessions and plan your route to hit all four bosses in one loop.
World 1 secret boss (Namek) – Broky
Broky is the Namek secret boss and serves as the early-game introduction to this system. The fight is straightforward, but the path asks you to chain jumps across floating platforms and up a cliff.
Where to start the quest
The World Line Giver NPC for Namek stands to the right of the Frieza boss. You need to speak to this NPC before killing Broky if you want the kill and rewards to register for the secret boss quest.
How to reach Broky
Why Broky is worth farming
At 1M HP and up to 54K Yen per kill, Broky is a strong early money farm. The Frizo and Broky artefacts also give an early stat bump that speeds up story progression, and this is usually the first secret route players can consistently clear without help.
World 2 secret boss (Shinobi Village) – Madera
Madera takes over as the hidden fight in World 2’s Shinobi Village. The boss sits on top of a building behind the main story boss area and pushes up the difficulty with 3M HP.
Where to start the quest
The World Line Giver for World 2 stands to the left of the Agony boss. Talk to this NPC before engaging Madera so your kills count toward the secret quest.
How to reach Madera
Why Madera is worth farming
Madera’s Yen payout can reach roughly 125K per clear, making it a solid mid-game money farm. The Madera and Agony artefacts offer another set of low-chance upgrades that stack with your World 1 drops, and clearing this route keeps you moving along a simple ground path with one vertical segment rather than complicated platforming.
World 3 secret boss (Hunters Domain) – Miruem
Miruem hides behind a waterfall in Hunters Domain and jumps health up to 10M HP. This is where the fights start to feel more like dedicated farm bosses than simple detours.
Where to start the quest
The World Line Giver in World 3 stands near the Chrullu boss at the end of the right-hand path through the map. Speak with this NPC before you start clearing Miruem so the run counts.
How to reach Miruem
Why Miruem is worth farming
With up to 400K Yen on the table per kill and access to both the Chrullu and Miruem artefacts, this fight offers a noticeable jump in both income and stat potential. The route is short once learned, and the main friction comes from the boss’s health pool and your ability to survive longer patterns while your units work.
World 4 secret boss (Desert Kings) – Flamingo
Flamingo, the World 4 secret boss, pushes the stat requirements much higher with 50M HP and a focus on vertical movement up a tall tower near the Crocodile boss.
Note: Flamingo’s location changed in an update. The boss now spawns on top of a tower to Crocodile’s left rather than behind the surrounding buildings.
Where to start the quest
The World Line Giver for Desert Kings stands behind the Crocodile boss. Make sure you speak to this NPC before climbing to Flamingo so your kills apply to the secret quest rewards.
How to reach Flamingo
Why Flamingo is worth farming
Flamingo offers the highest returns of the four, with up to 3M Yen per kill and two of the most desirable artefacts: Shanks and Doflamingo. Both drops follow the same 0.10 percent and 0.01 percent pattern as earlier worlds, making this boss a long-term target for late-game players looking to min-max stats and movement.
Movement, mounts, and changed locations
All four routes are designed to be completed with standard mobility. Double jump and dash are enough to clear every gap and reach every rooftop or platform. Mounts and flying tools cut travel time, especially on repeat runs, but they are not required to access any of the secret arenas.
Two secret bosses have had their locations adjusted by updates:
- Broky now spawns on the elevated area reached via floating islands from the Frieza arena rather than in an earlier ground-level spot.
- Flamingo now spawns at the top of the tall tower left of Crocodile instead of behind buildings in the same area.
If older routes you learned no longer line up with what you see in-game, use the paths above that rely on clear landmarks such as Frieza’s hill, Agony’s arena, the Hunters Domain waterfall, and Crocodile’s tower.
How artefacts work and why secret bosses matter
Artefacts are accessory-type drops tied exclusively to secret bosses. Each world’s hidden fight can drop two artefacts themed around itself and a nearby main boss, with one relatively rare option and one extremely rare one. These items provide damage, movement, or utility bonuses that stack with your units and other gear.
Because artefacts only drop from these encounters, skipping secret bosses means missing an entire progression layer. The power spikes from even a single drop make routine content and Yen farming faster, and that effect compounds if you run a full four-boss loop regularly.
For players who want even more free resources, Anime Celestial X supports periodic reward codes that you can redeem through the in-game code menu. Those codes are separate from secret boss farming but pair well with it, especially when they grant potions or currency boosts that shorten the grind.
Once you are comfortable clearing the main story bosses of a world, adding the corresponding secret fight and World Line Giver into your route turns daily runs into a reliable source of Yen and long-term artefact hunts.
