Best Honkai Star Rail Sunday Eidolons, ranked

The newest 5-star character, Sunday in Honkai Star Rail features a total of six Eidolons. Since Eidolons count as power-ups, the more Trailblazers have in their possession, the more potent the character’s abilities will become. Apart from the signature 5-star Light Cones, these power-ups play a significantly important role in boosting the unit’s capabilities.

This article lists all Eidolons for Sunday in Honkai Star Rail and ranks them based on their usefulness. Similar to previous iterations, this list will exclude the third and fifth ones.

Sunday’s Eidolons ranked in Honkai Star Rail

4) Sculpture’s Preamble

Sculpture’s Preamble is the least potent among Sunday's Eidolons in Honkai Star Rail. Apart from granting Energy to this Harmony unit when his turn begins, this powerup lets Sunday activate his ultimate often. Although that helps him keep the DPS units under "The Beatified" effect constantly, it is not that useful when compared to the others on this list.

If you are thinking of boosting Sunday’s effectiveness by pulling for these power-ups, it's recommended that you skip this particular one.

3) Millennium's Quietus

Sunday’s first Eidolon, Millennium's Quietus is a good one if you didn’t get to save up a lot of Stellar Jades. This power-up grants the targeted characters and their summons the ability to ignore the adversaries’ DEF while dealing damage. If paired with an AoE character like Jing Yuan, his summon—Lightning Lord will be able to dish out an absurd amount of damage.

Judging by how good Millennium's Quietus is, you should consider pulling for it in Honkai Star Rail version 2.7.

2) Faith Outstrips Frailty

Faith Outstrips Frailty is one of the best Eidolons for Sunday in Honkai Star Rail. If he has this power-up activated with a complete build, clearing end-game activities like Pure Fiction, MoC, and Apocalyptic Shadow becomes quite easy.

Faith Outstrips Frailty can replenish Skill Points, two to be specific when Sunday activates his Ultimate for the first time in every fight. Additionally, the damage buff from “The Beatified” gets a whopping 30% boost from this Eidolon. If you want your Sunday to be as effective as possible while spending the least amount of Stellar Jades, Faith Outstrips Frailty should be your best bet.

1) Dawn of Sidereal Cacophony

Finally, Sunday’s sixth/last Eidolon, Dawn of Sidereal Cacophony is the strongest one you can get for him. While the other powerups on this list grant minor buffs to his kit, the last one increases every single aspect of his abilities.

Since his damage-boosting buffs are CRIT-centric, Dawn of Sidereal Cacophony plays a major role in boosting their potency. It also indirectly grants an additional damage boost by converting the excess CRIT Rate into CRIT DMG. If you have the resources, this is a must-have Eidolon for Sunday in Honkai Star Rail.
