What Speed should my DPS aim for in Honkai Star Rail?

134 is the classic first target because it grants two actions in cycle 0. Faster teams push for 160.1, which gives two actions in most cycles. Anything in between those numbers gains little, so stop at a breakpoint and invest the rest in damage stats.

How is Action Value calculated?

Action Value equals 10,000 divided by Speed. Lower acts first: a 134-Speed character has an AV of about 74.6 and moves well before a 100-Speed enemy at AV 100.

Why is 134 Speed called a breakpoint?

Because 133.4 is the lowest Speed that earns two actions within cycle 0's 150 AV budget in Forgotten Hall-style content. Below it you act once in the opening cycle; at or above it, you act twice.

Does higher Speed give more energy?

Indirectly, yes. More actions per cycle means more Skills and Basic Attacks, which generate more energy and Skill Points — one reason supports and healers are usually built fast.

Speed is the most misunderstood stat in Honkai Star Rail. Stacking it feels productive, but its value arrives in steps, not smoothly: between two breakpoints, extra Speed changes almost nothing, and crossing one can transform how a character plays. This guide explains the math and the targets worth building for.

Action Value: how turn order really works

Every unit in battle has an Action Value (AV), calculated as 10,000 ÷ Speed. The lower the AV, the sooner the unit acts. A character at 134 Speed has an AV of about 74.6, so they take their turn well before an enemy at 100 Speed whose AV sits at a flat 100. When a unit acts, its AV resets based on its Speed, and the race starts again.

Endgame modes budget fights in cycles. In Forgotten Hall-style content, the first cycle (cycle 0) holds 150 AV and each later cycle holds 100 AV, so six cycles give you 650 AV of total action time. A breakpoint is simply the Speed at which a character squeezes one more full action into that budget.

The key breakpoints

Speed	What it earns across the first cycles
93.4	One action in every cycle — the floor for consistent tempo.
120.1	Two actions in cycle 1, on top of one per cycle elsewhere.
133.4	The first breakpoint with two actions in cycle 0 — the famous '134 Speed'.
146.7	Two actions in cycles 0, 2, 4 and 6.
160.1	Two actions in most cycles.
186.7	Two actions in every cycle.
200.1	Three actions in cycle 0, two elsewhere — extreme investment territory.

The 133.4 breakpoint earns its fame because cycle 0 is where fights are won early: two actions before the first cycle ticks over lets a damage dealer fire off a Skill and an Ultimate in the opening round, which is how 0-cycle Memory of Chaos clears are built.

Why more Speed is not always better

Three cautions before you strap Speed boots on everyone. First, between breakpoints, Speed is wasted — 145 Speed plays almost identically to 134 in a six-cycle fight, so those substat rolls usually serve you better as Crit or ATK. Second, some kits actively prefer going slow: Clara, for example, wants enemies to hit her so her counters fire, and a slow Clara gets hit more. Third, turn order inside your own team matters — supports should generally be faster than the damage dealer they buff, so the buff is up before the big hit lands in cycle 0.

Supports and sustains are the usual high-Speed builds: more turns mean more Skill Points generated, more energy, and faster Ultimate uptime for healing or cleansing. Damage dealers typically park at 134 or 160 and spend the rest of their budget on damage stats.

Where Speed comes from

A character's base Speed rises with level, and a few characters start naturally fast — Hanya and Seele top the base Speed charts, while Clara sits at the bottom by design. On top of that, Speed comes from the main stat of relic boots and from random substat rolls, which is exactly why it competes so fiercely with damage stats when you are deciding which relics to keep.
