The gaming community has witnessed the evolution of Sunday, the 5-star Imaginary character on the Path of Harmony, into one of Honkai: Star Rail's most versatile support units. His unique ability to empower allies and their summons has made him indispensable in the current meta, particularly after the groundbreaking Remembrance update. Sunday's kit revolves around amplifying damage output, boosting CRIT stats, and enabling rapid action sequences that can devastate opponents when properly built.
"Sunday completely transformed my approach to team building," explains veteran player Maya Chen. "His synergy with summon-based DPS units creates damage potential that simply wasn't possible before."
Indeed, Sunday's skill allows both a buffed ally and their summon to immediately take action while enhancing their CRIT Rate. His Ultimate regenerates Energy and applies 'The Beatified' status, granting a significant CRIT DMG boost based on Sunday's own CRIT DMG plus a fixed value. When his skill targets a Beatified ally, he recovers a valuable Skill Point - creating a powerful feedback loop for sustained combat advantage.
Light Cone Selection: The Foundation of Power
The cornerstone of any Sunday build is selecting the appropriate Light Cone. While several options exist, clear hierarchies have emerged in the competitive scene.
Top-Tier 5-Star Options:
-
A Grounded Ascent (Signature) - Remains unmatched after all these patches, providing Energy regeneration and stacking DMG buffs (up to 45%) when using skills on the same ally
-
But The Battle Isn't Over - Increases Energy Regeneration Rate by 10% and provides 30% DMG boost to the next ally taking action
-
Earthly Escapade - Boosts Sunday's CRIT DMG while automatically enhancing allies' CRIT stats
For players without access to these premium options, several 4-star alternatives remain viable:
-
Past and Future - The F2P champion, granting 16% DMG boost to the next ally taking action
-
Carve the Moon, Weave the Clouds - Provides random but powerful buffs
-
Planetary Rendezvous - Excellent for Imaginary-focused teams
"The gap between A Grounded Ascent and Past and Future has narrowed with recent balance adjustments," notes content creator JackGaming. "F2P players can absolutely make Sunday work without breaking the bank."
Optimal Relics and Ornaments
Sunday's effectiveness hinges on thoughtful gear selection that amplifies his supportive capabilities:
Relic Set: Sacerdos' Relived Ordeal
-
2-piece: +6% SPD
-
4-piece: After using Skill/Ultimate on an ally, target gains +18% CRIT DMG for 2 turns (stackable twice)
Ornament Set: Broken Keel
-
Effect: +10% Effect RES
-
When Effect RES ≥30%: All allies gain +10% CRIT DMG
When building Sunday, prioritize these stats in descending order:
-
CRIT DMG (aim for 200%+)
-
SPD (ideally 1 point less than main DPS)
-
Energy Regeneration Rate
-
Effect RES (minimum 30%)
-
HP
Team Composition Strategies
Sunday's versatility allows him to excel in numerous team configurations. His particular strength lies in enhancing characters with summons or those following the Path of Remembrance.
Top-Tier Sunday Teams in 2025:
| Core | Flex Slots | Strategy |
|---|---|---|
| Sunday + Jing Yuan | Robin + Bronya | Hypercarry with action acceleration |
| Sunday + Remembrance DPS | Pela + Lynx | Summon-focused damage amplification |
| Sunday + Imaginary DPS | Sparkle + Dr. Ratio | Imaginary damage exploitation |
| Sunday + Amphoreus | Robin + Healer | Memosprite multiplication |
"What makes Sunday exceptional is his ability to fit into almost any composition while providing meaningful buffs," explains esports coach Diana Wong. "Unlike specialized supports, he brings value to virtually any offensive strategy."
The recent introduction of additional Remembrance characters has only strengthened Sunday's position in the meta. His ability to double-buff both the character and their summons creates multiplicative damage potential that few other supports can match.
Trace Priority and Skill Development
Not all of Sunday's abilities contribute equally to his effectiveness. For optimal resource allocation:
-
Skill (highest priority) - The core of his kit
-
Ultimate and Talent (equal priority) - Critical to rotation effectiveness
-
Basic Attack (lowest priority) - Can be completely ignored
Sunday's Evolution in the Meta
Since his introduction, Sunday has transitioned from a solid support option to a meta-defining character. The introduction of the Remembrance path in Version 3.0 dramatically increased his value, and subsequent balance adjustments have only reinforced his position.
"If you're building a team around a summon-based DPS or Remembrance character in 2025, not including Sunday is essentially handicapping yourself," states competitive player Alex Rodriguez. "His value multiplies exponentially in those compositions."
Sunday represents the pinnacle of HoYoverse's support design philosophy - accessible enough for casual players to utilize effectively, yet with enough depth and scaling potential to satisfy optimization-focused veterans.
For players looking to maximize their account's potential in the current Honkai: Star Rail landscape, investing in Sunday remains one of the most impactful decisions possible. His combination of immediate action granting, CRIT stat enhancement, and summon empowerment creates a unique support package that continues to define the game's most powerful team compositions.
🌟 Pro Tip: When using Sunday with Remembrance characters, always apply his Ultimate before his Skill to maximize the CRIT DMG bonus during the immediate action turn!
Whether you're a day-one player or just starting your journey in Honkai: Star Rail, Sunday represents one of the most valuable additions you can make to your roster - a testament to thoughtful character design that has stood the test of time through multiple game updates and meta shifts.
