Light Cone Banners

Time Woven Into Gold (Aglaea): 635 ATK, 396 DEF, +12-20 SPD. Grants +54-90% CRIT DMG at max stacks—massive damage boost.

A Grounded Ascent (Sunday): Regenerates 6-8 Energy to allies, grants +36-54% DMG. Hard pity at 80 warps (12,800 Jades max).

Generally, new characters > signature weapons for account value, especially F2P.

Aglaea Analysis: Remembrance DPS

Level 80 stats: 1,241 HP, 698 ATK, 485 DEF, 102 SPD. Her Garmentmaker summon inherits 35% SPD and has Max HP = 66% Aglaea's HP + 720.

Garmentmaker acts independently, creating dual-damage system. Requires SPD breakpoints at 134/135 or 160/161 for optimal rotations.

Target Stats:

  • SPD: 134/135 minimum (160/161 for advanced)
  • CRIT Rate: 100%
  • CRIT DMG: 120%+
  • ATK: 2,600+

Main Stats: Body (CRIT Rate/DMG), Feet (SPD), Sphere (Lightning DMG%), Rope (ATK%/ERR)

Substats: CRIT Rate > CRIT DMG > SPD > ATK%

Best Teams

  • Hypercarry: Aglaea + Sunday + Tingyun + sustain

Honkai Star Rail Aglaea best team setups including hypercarry with Sunday and budget F2P variants

  • Dual Support: Aglaea + Sunday + Ruan Mei + sustain
  • Budget F2P: Aglaea + Yukong + Asta + sustain

Sunday is her premier partner—100% action advance affects both Aglaea and Garmentmaker, plus 30% base CRIT DMG + 12% from Ultimate.

Eidolon Value

E1: +25% DEF ignore = 18-22% damage boost. Strong but not essential.

E0 fully functional. E1 costs 14,400-28,800 Jades—better spent on new characters unless you have complete roster.

Sunday Guide: Harmony Support

Level 80: 1,241 HP, 640 ATK, 533 DEF, 96 SPD. Kit revolves around action manipulation and CRIT DMG amplification.

Skill: 100% action advance to ally + summon. Grants +30% DMG (standard) or +50% DMG (summons).

Ultimate: Restores 20% Max Energy (min 40), grants CRIT DMG = 30% of Sunday's CRIT DMG + 12%. With proper build, provides 60-80% CRIT DMG to carry.

Mechanics

100% action advance guarantees buffed character acts next—enables precise rotation control. Consumes one skill point per use.

Optimal SPD: 134, one point below DPS carry. Ensures Sunday acts immediately before buffed target.

vs Other Harmony Units

Honkai Star Rail Sunday vs Robin Ruan Mei Bronya harmony support comparison chart

Robin: Team-wide buffs, excels in follow-up teams Ruan Mei: Break efficiency, RES PEN, SPD buffs Bronya: Action advance + CRIT DMG but lacks energy regen

Sunday's distinction: energy regeneration + summon buffs create irreplaceable value for Remembrance teams. For Aglaea, his +50% summon DMG and Garmentmaker action advance outperform Robin/Ruan Mei.

Eidolons

E0 provides complete functionality. E1 increases damage bonus (+40% standard, +60% summons) but not essential. Better to invest in other characters.

Account Gap Analysis

Step 1: DPS Audit

Catalog existing DPS by element:

  • Lightning: Jing Yuan, Acheron, Serval
  • Physical: Clara, Sushang, Luka
  • Fire: Himeko, Asta, Hook
  • Ice: Jingliu, Yanqing, Herta
  • Wind: DHIL, Blade, Sampo
  • Quantum: Seele, Qingque, Xueyi
  • Imaginary: Dr. Ratio, Yukong

Identify gaps. Lack Lightning DPS? Aglaea fills critical weakness. Strong across all elements? Support depth matters more.

Step 2: Support Coverage

Assess Harmony/Nihility/Sustain depth:

  • Harmony: Bronya, Ruan Mei, Tingyun, Yukong, Asta, Hanya
  • Nihility: Silver Wolf, Pela, Welt, Luka, Sampo
  • Sustain: Aventurine, Luocha, Huohuo, Gepard, Bailu, Lynx, Natasha

Strong supports enable multiple teams from limited DPS. Sunday's universal applicability makes him high-value for support-deficient accounts.

Step 3: Endgame Performance

Review recent clears:

  • Memory of Chaos Floor 12: 36-star consistent? Which chambers fail?
  • Pure Fiction: AOE or single-target struggles?
  • Apocalyptic Shadow: Mechanics or damage issues?

Failure patterns reveal gaps. One team fails consistently? Need DPS (Aglaea). Both struggle with buff uptime/energy? Need support (Sunday).

Common Patterns

Strong DPS, Weak Supports: Sunday enables all DPS to perform higher.

Support-Rich, DPS-Poor: Aglaea maximizes existing support investments.

Elemental Gaps: Aglaea fills Lightning weakness.

Skill Point Issues: Sunday's energy regen reduces SP pressure.

Decision Matrix

Scenario 1: Lacking Premium DPS

Only 4-star DPS? Face fundamental damage limitations.

Recommendation: Aglaea. Provides immediate, substantial damage increases.

Scenario 2: Strong DPS, Limited Supports

Premium carries but only 4-star supports? Underutilizing DPS potential.

Recommendation: Sunday. Universally enhances all existing DPS.

Scenario 3: F2P Budget (<180 Pulls)

Must choose one character.

Recommendation: Execute diagnostic. Damage failures? Aglaea. Buff uptime/energy issues? Sunday. Uncertain? Sunday provides broader long-term value.

Scenario 4: Future Meta (Version 4.0)

Recommendation: Sunday ages better. Supports remain relevant across versions while DPS face power creep. Safer long-term investment unless critical DPS gaps exist.

Scenario 5: Collectors

Recommendation: Pull preferred character. Difficulty allows well-built 4-star teams to clear all content. Enjoyment > marginal efficiency.

Resource Management

Hard pity: 90 warps. Soft pity: 74 warps. Featured 5-star: 75% rate. Max cost: 180 warps (28,800 Jades) for guarantee.

Average cost: 72 warps (14,400 Jades) with soft pity.

Guarantee Math

At 0 pity, ~55% chance within 90 pulls. 45% need 180-pull guarantee.

14,400 Jades = ~50% chance if starting from 0 pity. Risk-averse players should budget for 180-pull guarantee.

Character vs Light Cone Priority

Light Cones provide 15-25% damage increase vs 4-star alternatives. New characters enable entirely new teams.

Priority:

  1. Missing characters filling gaps
  2. High-value E1/E2 Eidolons
  3. Signature Light Cones for main DPS
  4. Support Light Cones

Rerun Prediction

Both likely won't return until version 4.2-4.3 (4-6 months). Waiting means missing months of progression. Opportunity cost often exceeds Jade savings.

Trial Testing Protocol

Test 1: Rotation Smoothness Execute full cycle. Evaluate intuitiveness, SP constraints, energy generation.

Test 2: Damage Benchmarking

Honkai Star Rail Aglaea benchmark damage numbers for Skill 80k-150k and Ultimate 200k-400k

Record numbers. Aglaea Skill: 80k-150k, Ultimate: 200k-400k. Sunday buffs: +40-60% DPS damage.

Test 3: Team Synergy Test with existing roster. Compare to current setups.

Test 4: SP Economy Track SP across three cycles. Should maintain neutral/positive.

Benchmarks

Competitive Aglaea: 150k+ Skill, 350k+ Ultimate with standard buffs.

Sunday: +40% minimum DPS increase with full buffs.

Compare trial to current Memory of Chaos times. 20+ second improvement = meaningful upgrade. <10 seconds = marginal value.

Post-Pull Implementation

Week 1: Trace Leveling

Day 1-2: Ascend to 80. Prefarm materials before pulling.

Day 3-4: Prioritize Skill and Ultimate traces first.

Day 5-7: Complete Talent and bonus traces. Requires 3M Credits, 8 Tracks of Destiny.

Relic Farming

Expect 2-3 weeks dedicated farming for functional 4pc set. Focus correct main stats first, optimize substats over months.

Don't delay using character for perfect relics—functional builds > benched characters.

Team Integration

Identify who gets replaced. Test multiple configurations across 3-5 Memory attempts. Track clear times and survival.

Redistribute relics from replaced characters to accelerate implementation.

Alternative: Skip Both

4-Star Viability

Competent teams clear all content:

  • Team 1: Herta + Asta + Tingyun + Lynx
  • Team 2: Qingque + Bronya + Pela + Gepard

Require higher relic quality but achieve 36-star clears.

Save for 4.0

Arrives 6-8 weeks after Phase 3. Skipping accumulates 15k-20k Jades. 4.0 typically introduces meta-defining characters.

Eidolon Investment

Alternative: invest in existing character Eidolons. High-value targets:

  • Bronya E1: Removes Skill turn delay
  • Ruan Mei E1: Increases RES PEN
  • Seele E1: Additional talent triggers

Expert Recommendations

F2P/Low Spenders

Sunday. Universal support provides broader long-term value. Enhances all current/future DPS.

Exception: Zero premium DPS? Prioritize Aglaea for baseline damage.

Dolphin/Whale

Both, prioritize based on gaps. Dolphins can acquire both across Phase 3 and reruns. HSR Oneiric Shards top up via BitTopup enables budget-conscious acquisition.

Whales: E0 both minimum. Aglaea E1 > Sunday E1 for Eidolon value.

New Players (<3 Months)

Aglaea. Need DPS for story progression. Sunday requires existing DPS investment to generate value.

Alternative: If beginner pulls provided adequate DPS, Sunday enhances existing damage.

Endgame Veterans

Based on diagnostic. Execute complete gap analysis. Decision depends on which addresses larger bottlenecks.

Comfortable with current clears? Skip both, save for 4.0 or invest in Eidolons.

FAQ

Should I pull Aglaea or Sunday? Aglaea if lacking Lightning DPS or need second team damage. Sunday if strong DPS but limited Harmony supports. Sunday offers broader long-term value; Aglaea provides higher immediate damage.

Better for F2P? Sunday—universal support maintains relevance across versions. Exception: zero premium DPS needs Aglaea first.

Aglaea without signature? Yes, functions with 4-star alternatives. Signature provides 20-25% increase but character > weapon for account value.

Sunday universal support? Works with all DPS but excels with summon characters (+50% summon DMG). Doesn't replace Robin/Ruan Mei in all scenarios.

Jades for guarantee? Max 28,800 (180 warps). Average 14,400 (72 warps) with soft pity. Existing pity reduces costs.

Memory of Chaos requirements? Two functional teams with elemental coverage, sustain, sufficient damage. Aglaea addresses Wind-weak enemies; Sunday improves all compositions.
