Warframe Sirius Orion Strength Build & Clash Rotation

Updated 8 November 2026 · Standard formula, shown below

This guide explains how to build the Sirius Orion melee weapon for maximum Strength in Warframe, and how to correctly execute the Clash stance combo rotation to get the most damage. You’ll learn the best mods, the exact combo inputs, and how the stance’s forced procs work, so you can take this weapon into Steel Path and Archon Hunts with confidence.

What the Sirius Orion Is and Why Strength Matters

The Sirius Orion is a Tenno melee weapon released with the Jade Shadows update. It’s a heavy blade with high base critical chance and a unique gimmick: its heavy attacks and certain combos have forced Slash procs, which bypass armor. “Strength” in this context refers to two things: the weapon’s raw damage output (via mods) and the Strength of the forced status procs from the Clash stance. Unlike Warframe abilities, melee weapons don’t scale with Ability Strength, so building “Strength” means maximizing base damage, critical damage, and status chance to make each slash proc hit harder.

Best Sirius Orion Strength Build (Mods and Setup)

For a pure Strength build, you want to stack damage, critical, and attack speed. Here’s a proven setup that works for most content:

Stance: Clash (mandatory for the rotation below)
Sacrificial Steel – boosts critical chance to 220% (with Sacrificial Pressure), enabling orange crits.
Sacrificial Pressure – +165% melee damage, pairs with the above.
Primed Fever Strike – +165% Toxin damage for viral combo.
Shocking Touch or Voltaic Strike – electric for corrosive or viral+electric.
Berserker Fury – attack speed, crucial for combo fluidity.
Blood Rush – scales critical chance with combo multiplier.
Weeping Wounds – status chance scales with combo, making slash procs more frequent.
Organ Shatter (or Amalgam Organ Shatter) – +90% critical damage.
Primed Reach – optional, for range, replaces one elemental mod if you prefer.

For the Exilus slot, use Primed Smite Grineer or a faction mod if you’re min-maxing. The build focuses on critical hits and forced slash procs, which is the highest single-target damage for this weapon.

Clash Stance: Full Combo Rotation Explained

The Clash stance for heavy blades has three main combos. The one you’ll use for damage is the Rending Cleave combo (pause combo) and the Whirlwind Slash (forward block combo). But for a pure rotation that maximizes forced slash procs, you’ll alternate between the pause combo and the block combo.

Here’s the exact input sequence for a full rotation:

Start with the pause combo: E, E, wait 0.5s, E, E. This ends with a spinning slash that has a 100% forced Slash proc.
Immediately follow with the block combo: Hold right-click (or block key), then E, E, E. The final hit of this combo also forces a Slash proc.
Repeat: The pause combo’s final hit has a built-in forward lunge, which closes distance, so you can chain directly into the block combo without repositioning.

This rotation keeps your combo counter high and applies at least two forced slash procs per cycle. For heavy attack builds, you can replace step 2 with a heavy attack (right-click + E) to get a massive forced slash proc, but that consumes combo counter, so it’s better for a separate heavy attack build.

How Forced Slash Procs Work with This Rotation

Forced slash procs are status effects that are guaranteed to trigger on specific hits, regardless of your status chance. In the Clash stance, the pause combo’s final hit and the block combo’s final hit have forced slash procs. This is why the Sirius Orion is strong: even without status mods, you’ll get bleeds. But with Weeping Wounds and high status chance, you’ll also get viral procs from your elemental mods, which multiply the damage of those bleeds.

Note that the slash proc damage is based on the weapon’s base damage, modified by mods and combo multiplier. So building Strength (damage) directly increases the bleed damage. Critical hits on slash procs also multiply the bleed damage, so critical mods are essential.

Common Mistakes and How to Avoid Them

Not using the pause correctly: The pause combo requires a 0.5-second delay. If you press too fast, you’ll do the basic combo instead. Practice the timing in the Simulacrum.
Using the wrong stance: The Sirius Orion only works with heavy blade stances. Clash is the best for forced slash procs; Tempo Royale is better for mobility but has fewer forced procs.
Ignoring attack speed: Without Berserker Fury or a riven with attack speed, the rotation feels clunky and you’ll lose DPS. Attack speed also makes the pause timing easier.
Not building for viral: Slash procs are physical damage, but they’re amplified by viral status. Always include at least one cold and one toxin mod (or a combined elemental) to get viral.

Sirius Orion vs. Other Heavy Blades

Compared to the Galatine Prime or Gram Prime, the Sirius Orion has lower base damage but higher critical chance. This makes it more consistent for crit-based builds. The forced slash procs from Clash stance are identical across all heavy blades, so the Sirius Orion’s advantage is its high crit multiplier, which works well with the rotation above. If you don’t have the Sirius Orion, you can use the same build and rotation on any heavy blade, but you’ll lose some critical consistency.

Frequently Asked Questions

Does Ability Strength affect the Sirius Orion?

No. Melee weapons do not scale with Warframe Ability Strength. The term “Strength” in the context of this weapon refers to the damage output of the weapon itself, not the Warframe’s stats. Mods like Pressure Point and elemental mods are what increase its Strength.

Is the pause combo timing the same on all platforms?

Yes, the pause timing is the same, but the button prompt differs. On PC it’s the melee key (default E), on console it’s the melee button. The pause is always about half a second. If you’re having trouble, try using a macro or practice in the Simulacrum with a slower attack speed.

Can I use this build for the Archon Hunt?

Yes. The forced slash procs ignore armor, which is the main defense of Archons. However, you’ll need to strip the Archon’s adaptation with enough status procs. The viral+slash combo works well, but you may want to add a faction mod for Grineer to increase damage.

Should I use a riven for the Sirius Orion?

Only if you have one with good stats: attack speed, critical chance, critical damage, or damage. A riven can replace an elemental mod or the reach mod, but it’s not necessary for the build to work. The build above is already high-tier without a riven.

Why is my slash proc damage lower than expected?

Slash proc damage is affected by the weapon’s base damage and the combo multiplier, but not by critical damage mods unless the hit that applies the proc crits. Make sure you’re using the pause combo’s final hit, which has a forced proc, and that you have a high combo multiplier. Also, check that you’re not using a mod that reduces status damage, like some elemental mods that convert damage away from slash.

What’s the best Warframe to pair with this build?

Warframes that boost melee damage or attack speed, like Wisp (Haste Mote), Volt (Speed), or Mirage (Eclipse), are excellent. Also, frames that can armor strip, like Banshee or Saryn, will make the slash procs hit even harder. But the build works on any frame.
