How to play Sunday in Honkai Star Rail

Sunday's kit overview

As mentioned, Sunday in Honkai Star Rail is a 5-Star Imaginary Harmony unit whose role is to buff his teammates. He is one of the strongest Harmony characters in the game, and adding him to your team will increase your party's overall DMG output.

1) Basic ATK

Sunday's Basic ATK deals Imaginary DMG to one enemy. This DMG scales off the character's own ATK.

---

2) Skill

Sunday's Skill targets one teammate and allows them (and their summon) to immediately take action. Additionally, the DMG they deal is also increased. If the teammate has a summon, their DMG is increased by an additional ercentage.

---

3) Ultimate

When Sunday uses his Ultimate on a teammate, they regenerate Energy (based on their maximum Energy). Both the teammate and their summon are designated as The Beatified, and their CRIT DMG is increased for a certain number of turns.

Sunday's playstyle and rotations

Since Sunday is a buffer, he works well with DPS characters, especially those who have their own summons. This includes characters such as Jing Yuan, Topaz, and Lingsha.

With the Path of Remembrance coming soon in Honkai Star Rail 3.0, a lot of new characters with their own summons will be released, making Sunday a must-have unit for the region of Amphoreus.

For the time being, equip Sunday with a good build and make sure to use him in teams with standard damage-type DPS characters.

Sunday would work really well in a team with Jing Yuan and his Lightning Lord. Here is the character's ideal rotation for a team with these two:

• Use Sunday's Skill on Jing Yuan. This buffs and advances both him and Lightning Lord, and they immediately take action.
• Use Sunday's basic ATK and Skill alternately till his Ultimate is recharged.
• Use Sunday's Ultimate to restore Jing Yuan's Energy and increase both Jing Yuan and Lightning Lord's CRIT DMG.

This rotation applies to any DPS character that Sunday is paired with. Keep using Sunday's Skill and Ultimate on the teammate who can deal the highest DMG.

The best relic set for Sunday is the 4-piece Sacerdos’ Relived Ordeal. As for his Planar Ornaments, 2-piece Lushaka, the Sunken Seas is his best-in-slot.

Focus on the following main stats for the relic pieces:

• Body: CRIT DMG
• Boots: SPD
• Planar Sphere: DEF% or HP%
• Link Rope: Energy Regeneration Rate

Focus on SPD and CRIT DMG substats, as Sunday will need those the most. For his Traces, you can level them according to the following priority:

Skill > Ultimate > Talent > Basic ATK
