HSR Speed Breakpoints 2025: 90-160 SPD Tiers for Dahlia Super Break

2025/12/20
HSR speed breakpoints: AV = 10,000 / SPD, tiers 90, 93.4, 106.7, 120.1, 133.4, 146.7, 160.1 SPD. Dahlia (Dec 16, 2025) prioritizes Speed/Break Effect for Super Break; Clara 90 base low SPD, Seele 115 base high SPD.
What Are Speed Breakpoints in Honkai Star Rail?
SPD Basics and Action Value Mechanics
Here's the simple math: AV = 10,000 / SPD. Lower AV means you act first—it's that straightforward. Hit 90 SPD, and you're locking in 0 actions every cycle 4. Bump to 93.4 SPD? One action across all cycles. 106.7 gets you two in cycle 6; 120.1 nails two in cycles 1 and 6; 133.4 doubles up on 0, 3, and 6.
Just plug your SPD into the formula. Level up characters for those base SPD bumps—they add up fast.
Why Breakpoints Matter for Turn Order
Think Clara with her 90 base SPD: perfect for tanking without chasing speed. Seele at 115 base? She's built to blitz. Need at least 121 SPD for Topological Acceleration Band? Check.
To nail it:
- Calculate your team's AV sync.
- Chase SPD on relic substats.
- Test it out in Simulated Universe cycles.

HSR 2025 Meta: Why 160 SPD for New Supports?
Patch 2.7+ Changes Impacting SPD
May 2025 tier list (v3.2) shakes things up: Lynx pumps party Speed, Silver Wolf slows foes with debuffs, Asta advances turns. Super Break? It's screaming for 160.1+ SPD buffs.
Enter Dahlia, Fire Nihility dropping Dec 16, 2025. Dance Partner gives 35 Energy on entry, her Skill sets a 3-turn Zone with +50% Break Efficiency straight to Super Break. Synergies? Firefly, Rappa, Lingsha get zero-downtime loops; traces amp Speed/Energy for Fire allies.
New Supports Like Dahlia Analyzed
Dahlia thrives on Iron Cavalry relics and Sprightly Vonwacq planar for Speed focus. Eidolons crank Super Break DMG; her trace Lament recovers Skill Points.
Stack to 160.1 SPD for two actions in cycles 2 and 4. Pair with Asta's +36 SPD buff. Deploy that Zone through high action density—boom.
Do You Really Need 160 SPD? Pros vs Cons
Efficiency Comparison: 134 vs 145 vs 160 SPD
134 SPD: Two actions turn 1, then 6 by turn 4. Early pressure.
146.7 SPD: Two actions in cycles 0, 2, 4, 6. Balanced frequency.
160.1 SPD: Two in cycles 2 and 4. Tailored for support buffs.
Push to 173.4 for two in cycle 3; 186.7 for two all cycles; 200.1 for three in cycle 0.
Research on available data shows 160 SPD shines for Super Break zero downtime. Downside? Relic grind hell, and you lose Break Effect investment. (Editor note: I've crunched these in MoC clears—worth it for meta teams, overkill for F2P sustain.)
EHP Trade-offs for Sustain Supports
Clara's 90 base says don't overinvest—avoids EHP hits. Seele's high base makes it easier. Fugue (SS-tier Break) tunes high with Tribbie (S-tier Penetration).
- Check base SPD.
- Cap at breakpoint—no waste past 160.1.
Step-by-Step Guide to Hitting SPD Breakpoints
Relic Substat Priority
Musketeer 4-set nets +6% SPD; hunt Speed on body/rope.
- Farm those SPD main relics.
- Slap on Topological Acceleration Band for SPD.
- Asta's +36 team buff seals it.
Light Cone and Trace Priorities
Dahlia's traces boost Speed/Energy for Fire allies. Max the relevant ones. Slot SPD Light Cones. Sync Lynx/Silver Wolf Speed boosts.

SPD Breakpoint Tables for 2025 Supports
Doomspike Supports (e.g., Asta, Silver Wolf)
Asta's B-tier, but Silver Wolf's A-tier debuffs demand timing. 93.4 SPD: One action all cycles. 120.1: Two in 1,6. 160.1: Buffs land perfectly.
Harmony Sustain (e.g., Lynx, Dahlia)
Lynx (A-tier Speed healer); Dahlia +60% Super Break, 200% Follow-Up. Target 133.4 SPD for cycles 0,3,6. Test AV sync. Tweak for 50% Efficiency Zone Super Break.
Common SPD Mistakes and How to Avoid Them
Overstacking Without Team Sync
Slap 160+ on Clara? EHP tanks. Fix with AV=10,000/SPD—cap per role. Dahlia trap: Speed chase ignores Break Effect.
Ever seen your tank die first? Yeah, that's it.
Ignoring Enemy SPD Scaling
- Simulate team order.
- Cut overcaps.
- 121 SPD as baseline.
Case Studies: 160 SPD Clears in MoC & Pure Fiction
Dahlia at 160 SPD? Firefly zero-downtime with 35 Energy, 60% Super Break on Broken foes. Rappa meta pair; Fugue SS-tier amps it. F2P route: Asta + relics to 134 SPD for early clears. High-end: 186.7 SPD Seele owns all cycles.
Tools and Calculators for HSR SPD Tuning
Core formula: AV=10,000/SPD. Note bases (Clara 90, Seele 115). Layer buffs/relics. Iterate breakpoints.
Simple. Effective.
Future-Proofing Your Builds for 2025 Patches
Dahlia (Dec 16, 2025) demands Speed/Break Effect—farm Iron Cavalry, Tribbie traces. Weekly relics push 160.1 SPD. Super Break meta loves 146.7+.
