Best Honkai Star Rail Acheron Eidolons ranked

Eidolons in Honkai Star Rail unlock the hidden potential of the characters. While the 4-star units gain a decent amount of performance boost with each Eidolon, the 5-stars unlock a significant amount of hidden potential, and in Acheron’s case, it's the latter since she is a 5-star character. When Trailblazers unlock all Eidolons of most of the limited-time 5-star characters, including Acheron, they can become quite overpowered in most activities, turning down the difficulty a few notches.

In this article, we will be ranking every Acheron Eidolon in Honkai Star Rail.

Best Acheron Eidolons in Honkai Star Rail

6) Strewn Souls on Erased Earth

Among all six Acheron Eidolons in Honkai Star Rail, we have decided to put the fifth Eidolon in the sixth place as it is not as effective as the other ones. Although it's the fifth Eidolon, it only increases the level of Skill and Talent by two.

Compared to others, Strewn Souls on Erased Earth is not as useful, and if you are not aiming for all six, you shouldn’t pull for it.

5) Frost Bites in Death

Similar to the previous Eidolon, Frost Bites in Death boosts Acheron’s ultimate and basic attack level by two and one, respectively. However, as it boosts the Galaxy Ranger’s ultimate level, one of her primary sources of damage, we decided to place it in the fifth spot.

Additionally, obtaining Frost Bites in Death is easier and faster than Strewn Soul on Erased Earths.

4) Silenced Sky Spake Sooth

Silenced Sky Spake Sooth is Acheron’s first Eidolon and can easily be acquired after you get the 5-star character. Although it doesn’t grant Acheron a major damage boost, it can significantly increase her overall damage output with the additional 18% CRIT Rate against debuffed enemies.

Since this Galaxy Ranger requires at least one or two Nihility units to function properly, she can consistently use this Eidolon’s effects.

3) Shrined Fire for Mirrored Soul

The fourth Eidolon, Shrined Fire for Mirrored Soul, boosts Acheron’s damage potential by a significant amount. When she enters a fight, Acheron places a debuff that makes the enemies take 8% more Ultimate damage.

While this passive damage boost is decent, it is not worth it, as Trailblazers will have to acquire the previous three Eidolons, which cost a stupendous amount of Stellar Jades. We recommend that you should not pull for Silenced Sky Spake Sooth unless you are going for all six.

2) Mute Thunder in Still Tempest

Acheron’s second Eidolon in Honkai Star Rail, Mute Thunder in Still Tempest, is exceptional, and if luck is on your side, you can easily get this while spending a few Stellar Jades. Among all Eidolons except the sixth, Mute Thunder in Still Tempest can boost Acheron’s outgoing damage by a significant amount.

The passive Slashed Dream and Crimson Knot stack gain is exceptional and allows her to use her ultimate ability frequently. Additionally, it lowers the threshold of the allied Nihility units Acheron needs to proc The Abyss to the fullest. That grants the players a lot of flexibility when building a team.

1) Apocalypse, the Emancipator

As most players know, the sixth Eidolon usually makes the limited characters significantly overpowered in Honkai Star Rail and Acheron is no exception. Apocalypse, the Emancipator grants Acheron's ultimate a passive 20% damage boost while ignoring the opponent’s Weakness type.

This is significantly helpful when players are completing any high-tier/end-game activities. Moreover, in the usual Relic and Planar Ornament domains, she can single-handedly clear a wave of enemies.
