Sunday Build Guide: Maximizing Aglaea Remembrance Team Damage In Version Four Update
The Celestial Return: The Remembrance and Harmony Power Couple
Trailblazers, the stars have aligned once again! As we navigate the complex currents of the Amphoreus expansion, HoYoverse has just dropped a massive announcement that is shaking up the meta. The highly anticipated return of Aglaea (Remembrance: Lightning) and Sunday (Harmony: Imaginary) is imminent.
For those who missed their initial debut, or for veterans looking to vertically invest in their Eidolons, this is the moment we have been waiting for. These two characters are not just strong individually; they represent the pinnacle of the "Remembrance Summon" meta that has come to define the late Version 3.X and early 4.0 era. In this comprehensive recap and guide, we will dive deep into why these two are inseparable, how to build them for the current endgame content, and the smartest strategies to secure them for your roster.
Aglaea Recap: The Queen of Remembrance
Aglaea is the trailblazer of the playable Remembrance Path. Unlike the traditional destruction or hunt units we were used to in the early days, Aglaea introduces a mechanic that fundamentally changes turn economy: the "Memory Construct" (Summon).
As a Lightning character, Aglaea doesn't just deal damage; she summons a "Seamstress" entity to the action bar. This entity acts independently, dealing massive Lightning DMG based on Aglaea’s stats. The beauty of her kit lies in her Ultimate, which doesn't just nuke the enemy—it instantly Advances Forward her summon, effectively giving your team extra turns.
In the current #HonkaiStarRail meta, Aglaea is the gold standard for sustained DPS. She excels in longer fights found in Apocalyptic Shadow where consistent toughness breaking and frequent actions are key. If you struggled with the recent lightning-weak bosses in the Memory of Chaos, Aglaea is your solution.
Sunday Recap: The Conductor of Harmony
If Aglaea is the engine, Sunday is the supreme fuel. As an Imaginary Harmony character, Sunday was designed with a specific niche that has only grown stronger with time: Summon Buffing.
While characters like Sparkle and Bronya buff the character, Sunday buffs the Master and the Servant. His skill, "The Order's Baton," applies a unique state to an ally that increases the DMG of their summoned entities by a staggering amount. Furthermore, his Ultimate restores Energy to the entire team and provides a specific "Crit DMG" boost that applies solely to attacks initiated by summons or follow-up attacks.
This makes Sunday the best-in-slot support for Aglaea (and Jing Yuan, if you are still maining the General). He fixes the one issue summon-based characters have: the disconnect between the character's speed and the summon's speed. Sunday’s ability to manipulate the action value of summons specifically makes him a non-negotiable pick for the Remembrance team.
The Perfect Synergy: Why You Need Both
The synergy between Aglaea and Sunday is often described as "exodia" by the theory-crafting community.
Double Advance: Aglaea advances her summon with her Ult. Sunday advances Aglaea (or her summon, depending on his trace setup) with his Skill. This creates a loop where the "Seamstress" attacks 3-4 times in a single cycle.
Skill Point Efficiency: Sunday is surprisingly SP positive if built fast, which feeds Aglaea’s hungry rotation.
Element Coverage: Lightning and Imaginary cover a vast majority of the elite enemies in the current version, making this duo a "brute force" solution for almost any content.
If you already have Aglaea but lack Sunday, your priority for this rerun should absolutely be Sunday. The damage increase from replacing a standard support (like Tingyun or Ruan Mei) with Sunday in a summon team is calculated to be around a 40% overall DPS increase.
Pull Strategy: Eidolons or Light Cones?
With both banners running, resource management is critical. Here is the priority list for the average player:
Sunday E0: The support enables the archetype.
Aglaea E0: The DPS carry.
Sunday's Light Cone: Provides massive Energy Regeneration, which allows for a 3-turn Ultimate rotation.
Aglaea E1: Often enables her summon to ignore a portion of enemy DEF.
Aglaea's Light Cone: A great stat stick, but replaceable with Herta Shop options if you are tight on jades.
Economic Strategy: Preparing for the Double Banner
Let’s be realistic: a double rerun of top-tier meta characters is a threat to your Stellar Jade stash. Many Trailblazers have been drained by the recent Lunar New Year events. If you are looking at your jade count and sweating, you are not alone.
To ensure you don't miss out on this meta-defining duo, you need a smart financial plan. Buying directly from the in-game store is the standard route, but veteran players know there are more efficient ways to top up.
I highly recommend you take a moment to Google search for "buffget". It is a platform widely trusted by the high-tier community to optimize their gaming budget. By using buffget, you can discover options to buy cheap Monochrome (Oneiric Shards) that are safe and fast.
Typically, you can secure a discount of around 20% compared to standard regional pricing. That 20% savings can be the difference between hitting hard pity for Sunday or going home empty-handed. It is the smartest way to stretch your budget during these heavy banner cycles.
Relic Recommendations for the Rerun
Since their initial release, new Relic sets have dropped.
For Aglaea: The Hero of the Triumphant Moment set (released in 3.0) is her new best-in-slot. It grants bonuses specifically when a "Summon" takes action. If you are still running the Band of Sizzling Thunder, it is time to re-farm.
For Sunday: The Messenger Traversing Hackerspace remains solid for speed tuning, but the new Lushaka planetary set is excellent for buffing the team's Summon DMG if he is the fastest unit in the party.
Team Compositions: The "Remembrance" Core
The ideal team for this rerun cycle looks like this:
Main DPS: Aglaea
Buffer: Sunday
Debuffer/Sub-DPS: Pela (for DEF shred) or a Nihility unit.
Sustain: Huohuo (Energy Battery) or Aventurine (Follow-up synergy).
This team composition leverages the "HSRSpecialProgram" logic we saw in the livestream: stacking buffs that specifically target the "Summon" action bar to bypass standard turn limitations.
Conclusion: Don't Miss the Harmony of Remembrance
The return of Aglaea and Sunday is more than just a banner rerun; it is a second chance to buy into the strongest team archetype in the current version of the game. Whether you are struggling to clear Conundrum 12 in the Simulated Universe or just want to see big numbers in the Memory of Chaos, this duo delivers.
Plan your pulls carefully. Prioritize the support (Sunday) if you want longevity, but don't underestimate the raw power of the Remembrance DPS (Aglaea). And remember, if you need that extra push to reach pity, utilize buffget to ensure your resources are used as efficiently as possible.
The Express is leaving the station, Trailblazers. Make sure these two are on board before it departs!
