Weapon

Main article: Valkyr Talons

Valkyr Talons are  Valkyr and  Valkyr Prime's signature Exalted Weapon, summoned by activating the ability  Hysteria. The weapon exclusively uses the Hysteria stance.

---

• This weapon deals equal physical damage.
• Innate and two polarities.
• Negates the infinite combo extender of  Xoris, resetting combo count on activation.

Advantages:

• Tied with  Desert Wind for the highest critical chance of all melee weapons.
• Innate 5% lifesteal.
• Very high attack speed.

Disadvantages:

• Low status chance.
• Short range.
• Requires energy to activate and keep active.
• Damage isn't affected by the combo counter.
• As an Exalted Weapon, it cannot benefit from, nor contribute to the set bonus of any Set Mods (excluding the Sacrificial Mod Set; the Gladiator Mod Set can still apply if equipped on Warframe, Melee, or Robotic Weapons, and not on the Exalted Weapon itself).
• Cannot equip Melee Combo Counter Mods (except  Drifting Contact), Acolyte Mods (e.g.,  Blood Rush), or Amalgam Mods (e.g.,  Amalgam Organ Shatter).
• Cannot equip Melee Arcane Enhancements.

Stance

Main article: Hysteria (Stance)

Hysteria is a unique Stance exclusive to  Valkyr Talons that can only be acquired and used by activating  Valkyr's fourth ability,  Hysteria. This Stance overrides the Stance on any currently equipped melee weapon for as long as Hysteria remains active.

A "thrust attack" is a melee strike that intends to hit an enemy with the tip of the blade (the rounded edge of obround melee hitbox). A "360/spin attack" is a sliding sweep attack that hits targets around the player (not always in a 360° arc, but is usually above 180°). A "direct slam attack" is a melee strike that hits a single target at the epicenter of a slam attack. A "radial slam attack" is the area-of-effect component of the melee slam attack. Affected by the Seismic Wave mod. A "ranged attack" is any melee attack that launches a ranged projectile or can hit targets beyond melee range. View Full Legend Average Damage Multiplier per second only applies to single-target DPS calculations. Note that hits marked as "Radial Slam Attack" will not apply at the epicenter of a single target hit so these will not be accounted for in Avg Dmg Multi/s calculations. Combo animation lengths are approximate and are only accurate within a few tenths of a second. Each tile marking in stance preview gifs are 2m apart. Combos labeled with an asterisk (*) are shared between weapons within the same weapon type.
