Honkai: Star Rail Eidolon for Trailblazer

Eidolons enhance Character’s abilities or provide them with new passive bonuses. Each Character has 6 Eidolon upgrades with each Eidolon upgrade providing a different bonus.

While for the majority of characters the only way to get your hands on their Eidolon is to obtain their dupes (via Warps), there are a few exceptions with the main character - Trailblazer - being one of them. In case of the MC, instead of pulling his/her dupes you need to obtain some special items:

• Shadow of Destruction - for Physical Trailblazer
• Shadow of Preservation - for Fire Trailblazer
• Shadow of Harmony - for Imaginary Trailblazer
• Shadow of Remembrance for Ice Trailblazer

Here's a list of places where you can find all 6 Shadows of Destruction for your Physical Trailblazer:

1. Herta Space Station - Prologue reward,
2. Jarilo-VI - Main Story reward,
3. Trailblazer Rank 19,
4. Trailblazer Rank 30,
5. Internal Purchase Officer on Herta Space Station,
6. Underground Shop on Jarilo-VI.

Overall, since all of those items are available quite early in the game, you will be able to max your Physical MC Eidolon within the first few days of playing.

Here's a list of places where you can find all 6 Shadows of Destruction for your Fire Trailblazer:

1. Jeweler's Pagoda on The Xianzhou Luofu (you can get 4 Eidolons from there).
2. Main Story on The Xianzhou Luofu (you can get 2 Eidolons from there).

Below's video shows the location of the shop:

Here's a list of places where you can find all 6 Shadows of Remembrance for your Imaginary Trailblazer:

3. Event - When Charmony Rings Out (This event is permanent and unlocks the Imaginary Trailblazer for players who have not yet reached Penacony. If you have already unlocked the Imaginary Trailblazer, then this event will give you 1 Eidolon instead. For players who unlock the Imaginary Trailblazer via this event, the final Eidolon can instead be obtained during the Penacony main story)
