Relic Recon 3.7 runs November 5 to December 15, 2025 (server time, ends 03:59), handing out 120 Access Cards for those juicy +15 5-star relics. Hammer Phainon first (Physical DPS: CRIT Rate Body/SPD Feet), then Mydei (Imaginary DPS: CRIT DMG Body/HP Rope at 8000+ HP), and Cipher (debuffer: SPD Feet/CRIT Body). Every 8th box? 100% CR/150%+ CD mains or subs—guaranteed gold. Go DPS-first for full 6-piece sets.
Introduction to 3.7 Relic Recon Changes
What is Relic Recon?
You snag 120 Access Cards total: 48 from Version Missions (Amphoreus Act IV x8, Login Days 1/2/3 x8 each, Trailblaze Power at 240/480/720/960 x4 each). The rest—72—come from Event Missions (Snack Dash: 4 matches x6, 40k points x6; Currency Wars: Black Iron 1/Viridian Bronze 1/Jade Steel 1 x8 each, Cobalt Silver 1/Ice Titanium 1 x6 each, matches up to 8 x3 each).
Each card unlocks a +15 5-star Relic or Planar Sphere for one character slot (up to a full 6-piece set). They store in green lock slots—permanent after the event, with Variable Dice for rerolls. Every 8th? A Guarantee Box with ≥2 recommended subs.
Quick steps: Pick your character and sets. Grind cards daily. Open slots, eyeball the duplicates.
Key Updates in Patch 3.7
Fresh sets drop: Wavestrider Captain (perfect for Phainon—CRIT DMG+16%, ATK+48% after Ult), Scholar Lost in Erudition (Mydei loves the +8% CRIT Rate and +20% Skill/Ult DMG), Longevous Disciple (Mydei HP scaling), Sacerdos' Relived Ordeal (Cipher: SPD+6%, CRIT DMG+18% stacks), Pioneer Diver (Cipher debuff DMG boost). Planars shine too: Arcadia of Woven Dreams (Phainon +36% DMG), Bone Collection's Serene Demesne (Mydei +28% CRIT DMG at 5000+ HP).
Trailblaze Level 21+ required; those 120 cards equal 15 Guarantee Boxes. Currency Wars now gives 3 cards per match (cap 8); Trailblaze Power hits 4 cards each threshold.
Zero in on Physical and Imaginary DMG sets. Why? They fit your DPS cores like a glove.
Why Optimize Your Box Now

Phainon Relic Optimization
Best Main Stats (Body/Feet/etc.)
Body: CRIT Rate. Feet: SPD at 134-135 (Support role) or ATK% (DPS with E1+). Sphere: Phys DMG%. Rope: ATK%. Head: Flat HP. Hands: Flat ATK.
Chase these: 100% CRIT Rate, 150%+ CRIT DMG, 2500+ ATK—or push alt targets like 80-100% CR, 137 SPD, 140%+ CD, 3200+ ATK.
How? 1. Lock in Body/Feet Guarantees first. 2. Test equip in Enhanced State (40-80% ATK, 135-270% Max HP). 3. Reroll subs post-event.
Top Substats Priority
T1: CRIT DMG > CRIT Rate > ATK% > SPD. Coreflame pumps +15-30% CRIT DMG over 3 turns (+3 overflow); Cyrene stacks +6 Coreflames for +6% CRIT DMG (cap 36%) and +8% CRIT Rate. F2P floor: 60-70% CR/150%+ CD.
Do this: Hunt pieces with 4 CRIT subs. Dodge SPD mismatches—they wreck Coreflame timing.
Recommended Sets & Synergies
Wavestrider Captain 4pc hits 100% uptime. Scholar Lost in Erudition 4pc scores 97.6%. Planar: Arcadia of Woven Dreams 2pc; hybrids at 94.3%. Teams? Phainon/Trailblazer Ice/Tingyun/Lynx—smooth as butter.
Pro tip: Select sets, then Phys DMG Sphere via the magnifying glass.
Mydei Main Stats and Substats Guide
Ideal Main Stat Rolls
Body: CRIT DMG. Feet: SPD (135). Sphere: Imaginary DMG% or HP%. Rope: HP%. Benchmarks: 6000 HP minimum, 8000 optimal, 10000+ max (48% CRIT Rate from Bloodied Chiton at +1.2%/100 HP above 4000); 90-100% CRIT Rate/150%+ DMG.
Steps: 1. Nail HP Rope/Sphere/Body. 2. Vendetta at 100 Charge: 15-25% HP restore, +100% action fwd, +50% Max HP, 0 DEF.
Substat Tier List
HP% > SPD > CRIT DMG > CRIT Rate > ATK% > DMG. Minimums: 6000 HP/70% CR/120% CD. Optimal: 8000/90%/150%. Max: 10000+/100%/180%+.
Action plan: Stack HP% subs. Confirm 135 SPD Feet. Enhance subs post-event.
Build Variations for Content
Scholar Lost in Erudition 4pc edges Longevous Disciple 4pc (based on HP/CRIT stack data). Planars: Bone Collection's Serene Demesne vs. Rutilant Arena (Skill DMG at 70%+ CRIT Rate). Vendetta Godslayer: 140-280% ST/+84-168% adj DMG; 150 Charge for extra turns.
(Editor's take: Prioritize Skill/Ult DMG—2pc mixes save F2P backsides.)

Cipher Best Relics in 3.7
Sustain-Focused Main Stats
Body: CRIT DMG/Rate (or Effect Hit Rate for Acheron teams). Feet: SPD. Sphere: ATK%/Quantum DMG%. Rope: ATK%/ERR. Thresholds: 170 SPD (+50% CRIT Rate traces), 38% EHR (66.7% for 100% effects).
Hit it: 1. Feet SPD top priority. 2. Rope ERR for Ult spam. 3. Sig LC softens the 170+ SPD grind.
Substat Optimization
SPD > CRIT DMG > CRIT Rate > ATK%. Endgame: 170+ SPD/80-100% CR Rate/100+% CRIT DMG; EHR 38.8%+ for Acheron. 135/160 SPD unlocks Firmament +12/18% DMG.
Stack SPD subs. Pivot CRIT for non-Acheron. Test debuffs, FUA, tally in action.
Team Comp Integration
Pioneer Diver 4pc (+12% DMG on debuffed foes/+4% CRIT Rate/+8/12% CRIT DMG at 2/3 debuffs). Sacerdos' 2pc + Warrior Goddess 2pc for SPD. Planar: Firmament Frontline Glamoth 2pc; Sacerdos' 4pc stacks CRIT DMG on ally Skill/Ult.
Select for debuff DMG; slot in after DPS.
Cross-Character Box Optimization Strategies
Filtering Rules for Shared Relics
DPS leads (Phainon/Mydei with 4-sub CRIT). Then SPD/utility. Sync Guarantees: Feet SPD/ATK, Body CRIT/HP. Phainon tweaks SPD 134-135 Support vs. ATK% DPS; Mydei demands 8000+ HP; Cipher eyes 170 SPD.
Check priorities. 2. Share SPD Feet across teams. 3. Mains trump subs (70-80% value edge).
Prioritization Matrix
Main DPS: Phainon/Mydei. F2P? Single-char grind. 120 cards fill a full 6-piece. Hit restrictive mains early.
Gear DPS mains. Dupe best subs. Utility last.
Step-by-Step Relic Box Sorting
Using In-Game Scanner
Crack open a slot. 2. Peek green lock hints. 3. Swap if superior (4 subs, 2 effective Guarantees). 4. Save unused for Guarantees. One per slot max; test in Simulated Universe. No mid-event swaps—lock it in.
Substat Thresholds
Phainon: 100% CR/150%+ CD. Mydei: 8000 HP/90% CR/150% CD. Cipher: 170 SPD/38% EHR.
Post-event: Reroll T1 (Phainon CRIT>ATK>SPD).
Common Mistakes and How to Avoid Them
Ignoring Crit Ratios
Ever seen Coreflame fizzle on Phainon from SPD slips? Or Mydei dipping under 8000 HP, kissing 48% CR goodbye? Cipher below 170 SPD? Cyrene under 180 SPD tanks team DMG by 20%.
Fixes: Test equip now. F2P, slap on 2pc SPD (Messenger Traversing Hackerspace). Enhance before post-event rerolls.
Patch-Specific Traps
Don't tunnel single-char—spread for efficiency. No mid-event switches. F2P Phainon floor: 60-70% CR.
Daily grind: Snack Dash, Currency Wars cards.
