☛ Basic Introduction 

 

Sunday is an exceptionally potent Harmony support. He can advance a single party member including their summon by 100%, essentially giving them another turn, giving them a large DMG boost and his Talent increases the CRIT RATE of buffed party members. Additionally, he can restore single-party members a percentage of their Max Energy while increasing their CRIT DMG for a set amount of turns.

Honaki Star Rail Sunday

 

☛ Trace Priority 

 

Sunday relies mostly on his Skill and Ultimate rather than his Basic ATK. To maximize his potential, focus on upgrading his Skill and Ultimate with his Talent. His Talent is the second important one since it gives CRIT Rate to his buffed party members. In short, his trace priority is Skill = Ultimate > Talent > Basic ATK.

 

☛ Light Cones 

 

1. Best

 

Honaki Star Rail - Sunday signature light cone - A Grounded Ascent

 

A Grounded Ascent

 

After the wearer uses Skill or Ultimate on one ally character, the wearer regenerates 6 Energy and the ability's target receives 1 stack of "Hymn" for 2 turn(s), stacking up to 3 time(s). Each stack of "Hymn" increases its holder's DMG dealt by 15%. After every 2 instance(s) of Skill or Ultimate the wearer uses on one ally character, recovers 1 Skill Point.

 

This light cone gives the most benefit for Sunday by making Sunday from almost SP neutral to SP positive and giving his buffed party member extra DMG.

 

2. Good

 

Honaki Star Rail - light cone - Dance Dance Dance

 

 Dance Dance Dance

 

When the wearer uses their Ultimate, all allies' actions are Advanced Forward by 16%.

 

This light cone works best especially if you are trying to fit in extra turns in Memory of Chaos/Pure Fiction or AV in Apocalyptic Shadow and Sunday has a 3-turn ultimate rotation assuming he’s using Skill all the time.

 

Honaki Star Rail - light cone - But the Battle Isn’t Over

 

But the Battle Isn't Over

 

Increases the wearer's Energy Regeneration Rate by 10% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 30% more DMG for 1 turn(s)

 

This light cone works similarly to his signature light cone with having Energy Regeneration Rate, SP, and extra DMG for the buffed party member.

 

Honaki Star Rail - light cone - Past and Future

 

 Past and Future

 

When the wearer uses their Skill, the next ally taking action (except the wearer) deals 16% increased DMG for 1 turn(s).

 

This light cone gives extra DMG for the buffed party member and should be the base light cone for him if you don’t have the light cones mentioned above.

 

☛ Relics & Ornaments & Stats 

 

1. Relics

 

As for Sunday's best relics, Sacerdos' Relived Ordeal is the best choice for him.

2-Pc: Increases SPD by 6%.
4-Pc: When using Skill or Ultimate on one ally target, increases the ability target's CRIT DMG by 18%, lasting for 2 turn(s). This effect can stack up to 2 times (s).

☛ Recommended Teams 

 

A. Summon Team

 

Sunday’s kit makes him a powerful support character in a summoner-based team composition, where the DPS’s primary source of damage comes from their summon. His ability to advance a party member’s action by 100%, effectively giving them an extra turn, greatly benefits both the summoner and their summon, allowing for rapid consecutive attacks and maximizing overall DPS potential. This immediate action boost, combined with his significant DMG increase buff, allows Sunday to synergize well with characters like Jing Yuan, who can quickly rack up damage output from his summon.


In addition to action advancement, Sunday’s skillset provides valuable CRIT DMG and CRIT Rate boosts to the buffed ally, which is critical for enhancing the team’s overall damage consistency and burst potential. His Ultimate also enables him to restore a percentage of Energy for the buffed character, helping the DPS regain Ultimate charge faster, thereby maintaining high uptime on powerful skills. These attributes make Sunday not only a strong support for standard DPS characters but a particularly effective partner for those whose damage revolves around summons, as his buffs apply to both the summoner and their summon.

B. Hypercarry Team

 

Sunday isn’t just limited to summoner-based teams; he also excels in hyper carry compositions, where the strategy centers around empowering a single DPS character to deal most of the team’s damage. In a hyper carry setup, Sunday’s ability to advance a DPS character’s action by 100% becomes especially valuable, effectively granting the hyper carry extra turns and allowing them to maintain high DPS output without interruption. His powerful DMG boost and CRIT Rate increase further enhance the hyper carry’s burst potential, maximizing the effectiveness of each turn and helping the hypercarry reach even higher damage thresholds.

 

Sunday’s Energy regeneration support also pairs well with hypercarries that rely heavily on their Ultimates for high-damage output. By restoring Energy to the hyper carry, Sunday helps keep their Ultimate available more frequently, enabling consistent bursts of damage that can quickly eliminate enemies or handle high-HP bosses. Furthermore, with the right Light Cones, such as his signature one that regenerates Energy and boosts DMG over multiple turns, Sunday can maintain a positive SP balance, supporting the hyper carry without overusing Skill Points and ensuring a smooth rotation throughout extended battles.

 

In a hypercarry team with DPS characters like Seele, Dan Heng • Imbibitor Lunae, Jingliu, or Argenti, who benefit greatly from rapid, high-damage actions, Sunday’s kit amplifies both frequency and impact. His CRIT DMG and CRIT Rate boost enhance the hyper carry’s critical hits, and his turn advancement skill means the DPS can go again immediately, layering attacks that further stack up the damage. This makes Sunday flexible, invaluable support who can anchor both summoner-based and hyper-carry teams, making him a versatile addition to many team compositions.

In conclusion, Sunday is an exceptional Harmony support character, especially effective in a summoner-focused team composition. With his ability to advance a party member’s actions, provide significant DMG boosts, and support CRIT DMG and Energy regeneration, Sunday can be the key to unlocking the full potential of DPS characters who rely on summons. Properly equipping him with the recommended light cones, relics, and planar ornaments will ensure he maximizes his supportive abilities. By focusing on the appropriate trace priorities and team compositions, you can effectively integrate Sunday into a variety of team setups, enhancing both his synergy and overall team performance.
