Farming Timeline

Start Date: January 14-18

Begin 10-14 days before launch for optimal efficiency:

  • Daily regen: 240 Power (180 natural + 60 daily training)
  • 10-14 day total: 2,400-3,360 Power
  • Covers RNG variance + 2 weekly resets

Priority Order

Week 1 (Days 1-7):

  1. Weekly boss materials (time-gated)
  2. Stagnant Shadow materials
  3. Overworld enemy materials

Week 2 (Days 8-14):

  1. Crimson Calyx materials
  2. Remaining Stagnant Shadow runs
  3. Golden Calyx (Credits) if needed

Fuel Usage

Max Fuel capacity: 2,400. Use Fuel for Calyx farming (highest volume), save natural Power for Stagnant Shadow. With max Fuel, complete prefarm in 3-4 days.

Signature Light Cone Analysis

Aglaea: Time Woven Into Gold

  • SPD boost: +12 to +20 (S1-S5)
  • CRIT DMG stacks: +9-15% per stack, max 6 stacks (+54-90% total)
  • Basic ATK DMG: +9-15%

Performance: 18-22% DPS gain over best 4-star at S1, 25-28% at S5. Eases SPD breakpoint requirements (134/135+ or 160/161).

Sunday: A Grounded Ascent

  • Energy regen: 6-8 per activation
  • Hymn stacks: +15-24% DMG per stack, max 3 stacks (+45-72% total)

Performance: 12-15% team DPS gain at S1. Enables faster Ultimate rotations (15-20% more frequent).

Signature vs Eidolon

Aglaea E1: +25% DEF ignore (2 stacks) = 18-22% damage boost. Matches signature value, but signature eases relic requirements via SPD substats.

Sunday: Signature likely exceeds E1 value for most teams. Support Eidolons provide less individual value than DPS Eidolons.

Pull Strategy by Spending Tier

F2P ($0-15/month)

Income: 4,000-5,000 Jades/patch

Priority:

  1. Secure featured character (14,400 avg, 28,800 max)
  2. Save for future meta

Pull signature only if:

  • Won 50/50 early
  • Character is main DPS
  • Low Superimposition 4-star alternatives

Dolphin ($50-200/patch)

Can afford one character + signature with planning.

Approach:

  • Secure character first
  • Evaluate signature vs upcoming banners
  • Pull if next 2-3 patches lack must-pulls

HSR Oneiric Shards recharge via BitTopup maximizes monthly budget value.

Whale (Unlimited)

Standard: E2-E6 + S1 signature

  • Always get S1 for limited 5-stars
  • Prioritize Eidolons after signature
  • Target E2 breakpoints (largest DPS spike)

Account Progression

Early game (TL 1-40): Character roster only, skip signatures Mid game (TL 41-60): Consider signatures for main DPS Late game (TL 61+): Signatures become optimization priority

Farming Efficiency

Stellar Jade Budget

Phase 3 Income (15 days)

  • Daily Training: 1,800 Jades
  • Memory of Chaos: 800 (2 resets)
  • Pure Fiction: 800 (1 reset)
  • Apocalyptic Shadow: 800 (1 reset)
  • Events: 300-800
  • Gift of Odyssey: 10 Special Passes (1,600 value)

Total F2P: 5,600-7,400 Jades (35-46 warps)

Pull Requirements

Character:

  • Average: 72 warps (14,400 Jades)
  • Worst: 180 warps (28,800 Jades)

Light Cone:

  • Average: 65 warps (10,400 Jades)
  • Worst: 80 warps (12,800 Jades)

Budget Scenarios

  1. Single character: 28,800 Jades (guarantee)
  2. Character + signature: 41,600 Jades
  3. Both characters: 57,600 Jades
  4. Both + signatures: 83,200 Jades

Pity Management

  • Track via Warp > Records
  • Soft pity: 73+ (character), 65+ (LC)
  • 4-star pity: every 10 pulls
  • Guarantee carries between phases
  • Stop pulling at high pity on unwanted banners

Common Mistakes

  1. Prefarming before confirming pulls: Wait until you have guaranteed Jades (28,800 character, 41,600 character+LC). Exception: weekly bosses (time-gated, convertible).

  2. Neglecting Credits/XP: Reserve 2-3 days Power for Golden Calyx and Bud of Memories. Need 3,308,000 Credits + 400-450 XP books per character.

  3. Ignoring material overlap: Aglaea and Sunday share zero materials. Map overlaps before farming multiple characters.

  4. Poor Power management: Allocate 100% Power to prefarm during 10-14 day window. Pause relic farming and unnecessary activities.

  5. Late weekly boss start: Begin immediately when planning pulls. 12 materials = 4-6 weeks. Use Dream Ticker conversions to accelerate.

Team Compositions

Aglaea Teams

Core: Aglaea + Sunday + Harmony (Sparkle/Bronya/Tingyun) + Sustain (Aventurine/Luocha/Gallagher)

Material notes:

  • Sunday uses different Calyx (Harmony vs Remembrance)
  • Tingyun (Phase 3 rate-up) shares no materials
  • Aventurine uses Penacony materials (no overlap)

Alternatives:

  • Hypercarry: Aglaea + Sunday + Sparkle + sustain
  • Dual DPS: Aglaea + secondary DPS + Sunday + sustain

Sunday Teams

Optimal partners:

  • Aglaea (primary synergy)
  • Future Remembrance characters
  • Jing Yuan (existing summon DPS)

Priority: Build Sunday before other supports—his summon buffs (+50% vs +30%) are irreplaceable for Remembrance teams.

Multi-Character Farming

Efficient schedule:

  • Mon-Wed: Aglaea Stagnant Shadow + Calyx
  • Thu-Sat: Sunday Stagnant Shadow + Calyx
  • Sun: Weekly bosses
  • Daily: Overworld materials
