HSR 3.7 Amphoreus Guide: +8% CRIT Rate & Team SPD

Diving into 3.7's Planar Ornaments

Amphoreus drops Nov 4, 2025 (NA), or Nov 5 (EU/Asia) during 3.7 Phase 1. Tengoku hits the same window, zeroing in on Memosprite comps that churn out 6 Recollections per cycle. Amphoreus amps CRIT Rate and team SPD; Tengoku piles on CRIT DMG by burning SP. Farm Amphoreus from Nov 4–26, and hit Relic Recon Nov 5–Dec 15 for those extra +15 5-star pieces.

Breaking Down Amphoreus, the Eternal Land

2-Piece: Straight +8% CRIT Rate (stacks with 4pc) that shines on Cyrene or Hyacine.

4-Piece: +8% SPD for the whole team whenever a Memosprite's on-field (non-stackable). It procs off RMC summons, easily outrunning 174 enemy SPD once your allies hit 200+ SPD.

The numbers don't lie: Hyacine breaks 200+ SPD for 85-95% Pure Fiction clears and 0-cycle Stages 9-12. Cyrene gets +40% MoC summon DMG and +28% true DMG from Memosprites.

How to build? Equip it on RMC first. Feet for SPD, Body CRIT Rate, Rope ERR. Substats? SPD > Talent > Skill > Ult > Basic. Pair with 2+2 Rutilant Arena or Vonwacq.

(Quick editor note: I've seen too many players sleep on this for speed-tuned teams—it's a game-changer.)

Tengoku@Livestream: The Full Scoop

2-Piece: +16% CRIT DMG, no questions.

4-Piece: Another +32% CRIT DMG if you're burning 3+ SP per turn for 3 turns—tops out at +48%, neck-and-neck with Celestial Differentiator.

Proof in the data: Archer squeezes out +3.5% burst DPS over BananAmusementPark; pairs great with A+ tier SP-cyclers like Sparkle or Bronya.

Build steps: Slap it on Archer (BiS), DHIL (3-SP Skills), or Qingque (3 tiles). Commit to 3 SP/turn burn. Substats lean CRIT DMG/SPD. Farm it on-demand versus Lushaka.

Head-to-Head: Amphoreus or Tengoku?

Amphoreus is high-priority for Memosprite squads; Tengoku's a medium pick for SP-draining DPS.

SPD/Team Boost: Amphoreus's +8% crushes Tengoku's zero.

Comparison of Amphoreus and Tengoku Planar Ornaments in Honkai Star Rail

CRIT Edge: Rate for supports (Amphoreus); up to +48% DMG for DPS (Tengoku).
Who Fits? Amphoreus owns Remembrance (RMC/Hyacine/Cyrene); Tengoku barely touches supports.
Farm Order: Amphoreus must-farm; Tengoku whenever.

Performance-wise, Amphoreus nails sub-3 MoC in Triple Remembrance (6 Recollections/cycle). Tengoku hits +72% CRIT DMG on Phainon+Cyrene—but SP mismatch kills healers.

Test it yourself: Run Simulated Universe. Compare 200+ SPD Hyacine on Amphoreus vs. Tengoku. Farm Amphoreus for those Memosprite comps first.

Tailored Picks for Remembrance Supports

RMC (1): Full 4pc Amphoreus for lightning-fast Memosprite summons.

Hyacine (2): 2pc Amphoreus + 4pc Warrior Goddess (5000+ HP, 200+ SPD, 130%+ CRIT DMG, 30%+ Effect RES, 140 Energy). A6 guarantees 100% CRIT Rate, +40% DMG to Memosprites; Sig LC adds +30% SPD and 500% DMG.

Cyrene (3): 4pc Amphoreus (+70 Energy, 300% amp, +40% DMG to non-Chrysos for 2 turns, +50% CRIT Rate on Ult). SS at E0S1; E1 edges out sig LC.

Trailblazer Ice/Evernight: Plug the SPD/CRIT Rate gaps. F2P E6 TB with Herta/Tingyun/Gepard clears 70%+ content.

Pro tip: Hyacine ascension needs 15 Fear-Stomped Flesh, 15 Courage-Torn Chest. Rotation? RMC Mem → Cyrene Skill → advance → resummon. Prioritize 8 Tracks of Destiny, 3M Credits in traces.

Ever wonder why Remembrance feels mandatory right now? It's that team-wide speed.

Smart Farming Plays

Radiant Feldspar in Penacony: 40 Trailblaze Power and 1 Immersifier per run. Amphoreus is top priority (shares with Lushaka); Tengoku's secondary.

Events juice it up: Planar Fissure Nov 17–Dec 1 for double drops; Relic Recon Nov 5–Dec 15 (+15 5-stars).

F2P route: E6 TB + S5 Memory's Curtain (86% DPS/12% SPD). Whales? Full Amphoreus on Cyrene/Hyacine for sub-3 MoC.

Daily grind: 40 Power into Amphoreus. Stock Immersifiers. Watch for 2+2 inconsistent triggers.

Pitfalls to Dodge

Don't slap Amphoreus on non-speed-tuned teams (Vonwacq suits Cyrene better there). Tengoku demands 3 SP/turn—skip if your sets already deliver. Zero Tengoku synergy with Remembrance (SP clash). Always resummon dead Memosprites; hybrid 2pc falls short of full 4pc.

Quick fixes: Test rotations in Simulated Universe. Stack 30%+ Effect RES on Hyacine (A4 cleanse). Ditch high-ER Bronya.

Real Test Data & Benchmarks

Amphoreus shines: Hyacine 20-30% faster than Acheron; Cyrene sub-3 MoC, +72% CRIT DMG paired with Phainon; PF 85-95% clears versus hypercarry's 3-4 cycles.

Tengoku: Archer +3.5% burst; matches BananAmusementPark.

Key metrics: MoC at 6 Recollections/cycle in Triple Remembrance; PF 0-cycle 9-12 with 200+ SPD.

(My take as editor: These numbers come from community sims—your mileage varies with relics, but they're rock-solid baselines.)

When to Grab What

Go Amphoreus for any Memosprite/Remembrance core. Tengoku? SP-heavy Archer/DHIL, farm on-demand. Alternatives: Vonwacq (Cyrene), Warrior Goddess (Hyacine), BananAmusementPark (Archer).

Future-proof bet: Amphoreus into 3.8+. MoC reset Dec 8 (800 Jade free).

Start with Amphoreus on supports; Tengoku for SP beasts.
