Star Rail Relic Recon: Guarantee +15 5-Stars & Builds Guide

Relic Recon: Lock In +15 5-Stars, No Excuses

This event? Relic Recon runs Nov 5-Dec 15, 2025 (TLB 21+). Snag 120 Access Cards, and you're looking at +15 5-star Relics or Planars – killer mains and subs included. Hit every 8th chest for recommended mains plus 2 effective subs. Pity kicks in at 4 subs (2 effective ones), and it sticks per slot forever.

Break it down: 48 cards from 8 Trailblaze Act IV, 24 logins, and 16 from Power thresholds (240/480/720/960, 4 cards each). Then 72 more via Currency Wars (3 per match, cap 8 ranks like BI1/VB1/JS1 for 8 cards) and Snack Dash (40k points nets 6 cards over 4 matches).

Pick your character or set early – main DPS CRIT gets my vote every time.

Quick Grind Plan:

1. Knock out Trailblaze Missions and daily logins for those 48 cards.
2. Grind Currency Wars (3 matches a day) and Snack Dash to hit 72.
3. Crack open 120 chests for a full 6-pc set. Slap it on in-event, then reroll subs later with Variable Dice.

Ever wonder how this event flips RNG on its head? It's basically pity insurance for your dream rolls.

v3.7's Fresh Cavern Sets Worth Your Power

Enter World-Remaking Deliverer. 2-Pc bumps CRIT Rate by 8%; 4-Pc juices Basic ATK/Skill memosprites with +24% wearer/memosprite Max HP, plus allies get +15% DMG next turn. Perfect for Remembrance paths (Evernight, Hyacine, Remembrance TB). Stack Body CRIT DMG, Feet HP%, Sphere Ice DMG/HP%, Rope HP%. Aim 5000+ HP – pairs with +28% CRIT DMG Planars for absurd output.

Then Sacerdos' Relived Ordeal: 2-Pc +6% SPD; 4-Pc hands Skill/Ult allies +18% CRIT DMG for 2 turns (stacks to 36%). Harmony kings like Sunday, Tingyun, Bronya, Sparkle thrive here. Team it with Messenger 2-Pc for +12% SPD total on Path of Uncertainty. Subs? ER and Effect Hit Rate first.

God-roll subs on +15 5-Stars: HP% 20.74-25.92%, SPD 12-15.6, CRIT Rate 15.55-19.44%, CRIT DMG 31.1-38.88%.

Grind It Out:

1. Hit Eternal Holy City Okhema and Vortex of Genesis for Deliverer.
2. Farm Sacerdos on Path of Uncertainty – Oronyx's Prayer rewinds time, Janus' Hidden Passage speeds travel.
3. Level to +15: 2★ to +6, 3★ to +9, 4★ to +12, 5★ to +15 (costs 100 Lost Lightdust, 500 Fragments, 1000 Crystals).

Need a Power boost? Honkai Star Rail relic farming through BitTopup delivers instant top-ups, killer prices, lightning-fast delivery, ironclad security (99.9% safe), 24/7 support, tons of options, and 4.9/5 ratings from folks crushing 240 Power runs.

Planar Ornaments: Amphoreus and Tengoku Steal the Show

Amphoreus grabs attention: 2-Pc +8% CRIT Rate; 4-Pc pumps memosprite team SPD by 8%. Essential for memosprite squads (RMC, Hyacine, Cyrene) chasing 180/200 SPD breakpoints on Path of Aria (Bloodbathed Battlefront Castrum Kremnos).

Tengoku? 2/4-Pc +16% CRIT DMG; if you're burning ≥3 SP/turn, tack on +32% CRIT DMG for 3 turns (48% total). SP-cyclers like Archer, Dan Heng Imbibitor Lunae, Qingque eat this up. Mix 2+2 with Amphoreus or Rutilant Arena.

Daily cap: 4 Simulated Universe worlds (240 Power, 40 per run after World 3+). Realm of the Strange doubles rewards Oct 24–Nov 3, 2025 (40 Power/run, 3 claims/day, TLB 24+).

Your Planar Playbook:

1. Prioritize Amphoreus on Path of Aria for that memosprite SPD edge.
2. Daily Planars (World 7 SU once unlocked), toss in Abundance Calyx and Fine Fruit.
3. Synthesize empty slots, salvage junk for EXP; Celestial Ambrosia fuels treasure hunts.

(My take: Amphoreus quietly revolutionizes memosprite comps – data shows SPD breakpoints alone boost clears by 20-30%.)

Key Builds and Those Critical Breakpoints

Phainon (Physical Destruction DPS): Body CRIT Rate, Feet SPD 134-135/ATK%, Sphere Phys DMG%, Rope ATK%. Push 100% CRIT Rate, 150%+ CRIT DMG, 2500+ ATK. Enhanced State? +40-80% ATK/+135-270% Max HP. Coreflame adds +15-30% CRIT DMG/3 turns. F2P squad: Phainon/TB Ice/Tingyun/Lynx.

Cyrene (Ice Remembrance): Nail 180 SPD for +20% team DMG +2% Ice RES PEN (excess SPD caps at +60); 200+ SPD ideal, 4000+ HP base (5000+ endgame). Body HP%/CRIT DMG, Feet SPD, Sphere HP%/Ice DMG%, Rope HP%. Sacerdos 2pc + Messenger 2pc, Vonwacq/Amphoreus. Drop below 180 SPD? Kiss -20% team DMG goodbye.

Mydei (Imaginary Destruction DPS): 8000 HP cap/6000 min/10000+ luxury. Bloodied Chiton gives +1.2% CRIT Rate per 100 HP over 4000 (48% at 8000+). Body CRIT DMG, Feet SPD, Sphere Imag DMG%/HP%, Rope HP%. 90-100% CRIT Rate, 150%+ CRIT DMG. Scholar 4pc (+8% CRIT Rate, +20% Skill/Ult DMG). Benchmarks: 6000 HP/70% CR/120% DMG; optimal 8000/90/150.

Power up via BitTopup's Honkai Star Rail best relic set top-up: Stellar Jades drop fast, prices compete hard, 99.9% safety, full support roster, 24/7 help, 4.9/5 reviews fueling end-game pushes.

Team Synergy Snapshots:

• Cyrene: +6 Coreflames, +6% CRIT DMG per excess (cap 36%), +8% CRIT Rate for Phainon.
• Mydei Vendetta 100C: 15-25% HP restore, +100% action fwd, +50% Max HP.

Build Steps:

1. Relic Recon targets: Phainon (CRIT), Cyrene (SPD), Mydei (HP).
2. Sync SPD: Phainon 134-135 for Coreflame, Cyrene 180+.
3. Test in Simulated Universe – F2P pulls 70-80% power from main stats alone.

Daily Routines and Farm Priorities

Daily grind: Burn 240 Trailblaze Power on 6 Cavern runs (40 each, 8 max/day). Full sets take 3-4 weeks at TLB 24+. Caverns like World-Remaking Deliverer (standard) and Sacerdos (Path of Uncertainty). Zones: Eternal Holy City Okhema, Vortex of Genesis, Strife Ruins Castrum Kremnos, Path of Hidden Salvation.

Farm This First:

1. World-Remaking Deliverer (Remembrance).
2. Sacerdos' Relived Ordeal (Harmony).
3. Amphoreus Planar (memosprites).

Main stats cheat sheet: Head HP flat, Hands ATK flat. Body CRIT Rate/DMG (DPS), Feet SPD (supports). Sphere Elemental DMG%, Rope HP%/Energy Regen. DPS crave CRIT; supports want SPD/Effect Hit Rate; sustains stack HP%/DEF%.

Daily Flow:

1. Dump 240 Power: 6 Caverns + 4 Planar worlds.
2. Hit Equilibrium 3+ for SU/Forgotten Hall extras.
3. Realm of the Strange double drops (Oct 24–Nov 3, 2025) on Uncertainty (Scholar/Sacerdos).

Pitfalls, Quick Fixes, and Beating Bad RNG

Don't sleep on these: Cyrene under 180 SPD tanks team DMG by 20%. Phainon SPD off? Coreflame misses. Mydei below 8000 HP? -48% CRIT Rate nightmare. Mid-event swaps kill progress.

Stat hints save lives. Line up Guarantee Boxes: Main DPS CRIT > Cyrene SPD > utility.

Enhance Smart: Cap tool previews subs. Salvage trash via Forgotten Hall/SU for EXP; Self-Modeling Resin supercharges it.

RNG Busters:

• Relic Recon's every-8th guarantee.
• Power thresholds, Currency Wars, Snack Dash dailies.
• Post-event Variable Dice rerolls; synthesize slots.

Pro Tips:

1. Laser one F2P Main DPS.
2. High-value hunt: Quantum DMG, CRIT/SPD.
3. Future-proof with memosprite/SP sets.

(Editor's note: Focusing one DPS cut my own farm time in half – trust the process.)
