- After the trailblazer and the entire team come to the rescue and Seele calls Cocolia a witch, she becomes the Mother of Deception, and, you have to go through hell to fight through her phases.
- After the boss fight and the mission was completed, she was unlocked as a weekly boss fight that could be farmed.
- Getting to the bosses can be extremely easy since all that needs to be done is to open the Survival Index, go to the Echo of War tab, and teleport to the location.
Doomsday Beast
The Doomsday Beast is among the first bosses in the Honkai Star Rail Echo Of War. The Boss itself can be farmed 3 times as the Echo of War offers 3 runs per week, and it resets every Monday at the usual reset time.
It uses 30 trailblaze power to get one drop and has 2 phases. Its main weaknesses include Physical, Fire, Ice and Wind, and it is resistant to Control Effects and Entrancement. There are three main parts to the Doomsday Beast, as listed below.
- Disaster’s Right Hand is one of the first parts, and it is weak to elements like Fire and Ice but resistant to Quantum and Imaginary.
- The Dawn’s Left Hand is weaker, seemingly to elements like Fire and Wind, but is resistant to Quantum and Imaginary.
- The Antimatter Engine has been known to be weaker to elements like Physical and Fire but will be resistant to elements like Imaginary and Quantum, and all three parts will be resistant to Entrancement.
The Doomsday Beast will drop items like the Destroyer’s FInal Road, Lucent Afterglow, Musketeer of Wild Wheat, and Thief of Shooting Meteor.
- Alongside that, there is a chance that it can drop light cones, too (Four-star).
Best Team Comps To Use
Moving on, now that the weaknesses and resistances are known, let’s look at team comps that can be used to beat it.
- The Doomsday Beast is particularly weak to Fire, making it an essential element in a team comp.
If a mono-Fire team needs to be run with Fire-based characters, such as Himeko, Asta, or Hook, it can be used in comps. Any healer, such as Natasha or Bailu, can be used here.
Other than that, best characters, such as Asta, can be deemed pretty crucial for shield shredding, and on March 7th, Dan Heng and Natasha can be free-to-play units that can be used. Below are the best relics that can work for the characters in the fight against the Beast.
| Characters | Best Relics | Best Ornament Set |
| Himeko | Hunter of glacial frost | Space sealing station |
| Asta | Firesmith of lava forging | Fleet of the ageless |
| Hook | Firesmith of lava forging | Space sealing station |
| Bailu | Passerby of wandering cloud | Fleet of the ageless |
| Natasha | Passerby of wandering cloud | Fleet of the ageless |
| Dan Heng | Eagle of Twilight line | Space sealing station |
| March 7th | Knight of purity palace | Belobog of the architects |
Doomsday Beast Abilities
Moving on, quite a few abilities must be faced whenever a fight against the Doomsday Beast occurs.
Antimatter Engine
There are a total of 6 abilities that the Anti-matter Engine will have. They are listed as follows.

Cocolia
Moving on, when it comes to the second boss, it is essentially Cocolia, Mother Of Deception, which has two phases and will reset every Monday at the usual time that the server ends up resetting. It requires 30 Trailblaze Power to acquire the drops.
It is pretty weak to elements like Fire, Quantum, and Lightning but will have resistance to Physical, Ice and even Wind, alongside being pretty resistant to Frozen and Imprisonment. Alongside that, it has two main parts listed as follows.
- One of the first parts is the Lance of Eternal Freeze (Right) which is extremely weak to fire and Lightning but is resistant to Frozen.
- The second part is the Lance of Eternal Freeze (Left), which is weaker to elements like Fire and Quantum but is resistant to frozen.
After defeating her, she can drop relics and Ascension mats, such as Destroyer’s Final Road, Lucent Afterglow, Musketeer of Wild Wheat, and Thief of Shooting Meteor.
- She can also drop light cones like quid pro quo; wildfire, fermata, the river flows in spring, past, and future, woof walk time, and the seriousness of breakfast.
Best Team Comp To Use
Regarding team comps, it’s better to build teams that use characters with elements Cocolia could succumb to. She is pretty weak to Fire; therefore, focus on bringing Fire-based characters, such as Himeko or Hook.
The Fire MC is also incredibly good at tanking damage from Cocolia’s attacks; therefore, stacking Defense on her/him and bumping up their overall defense is essential. Single-target DPSes such as Seele can work well, too, considering she can take more damage when Cocolia is weakened.
Therefore, using characters like Serval, Seele, or Himeko is viable, and healers can include Natasha or Bailu. Below mentioned are the recommended relic sets for these characters.
| Characters | Best Relics | Best Ornament Set |
| Himeko | Hunter of glacial frost | Space sealing station |
| Hook | Firesmith of lava forging | Space sealing station |
| Bailu | Passerby of wandering cloud | Fleet of the ageless |
| Natasha | Passerby of wandering cloud | Fleet of the ageless |
| Fire Trailblazer | Knight of purity palace | Belobog of the architects |
| Qingque | The genius of brilliant stars | Celestial differentiator |
| Serval | Band of sizzling thunder | Space sealing station |
Cocolia’s Abilities
While being busy admiring- I mean annihilating Cocolia, it’s crucial to know of the abilities she can pull off on you, with her primary abilities and using her Lances.
| Abilities | Description |
| Bone-Shattered Cold | Willd eal ice damage to one target. |
| Soulrend Coldstream | It will deal insane amounts of Ice damage to one target. |
| Harbinger of Annihilation | It locks onto one target and then uses Soulrend Coldstream on them. |
| Heartless Annihilator Call | Brings forth Lances of the Eternal Freeze. |
| Creator’s Resolve | After changing the form that she is in, she gains Speed and can deal Imaginary damage. |

| The Creation’s Prelude | It goes into the charge state, and the subsequent attack can use the Genesis Absolute Sound on all targets. |
As for the Lances, they can use their Everwinter Reverberance abilities to deal Ice damage to their teammates.
