INTRODUCTION

This build focuses on staying in Hysteria form at all times to be invulnerable to all damage and killing with her Exalted [Talons], grouping with [Prolonged Paralysis] (~20m range), 100% armor stripping with an armor strip such as Tharros Strike and speeding up attack speed by approx 85% with permanent Warcry (due to [Eternal War]). Grouped enemies can be stripped all at once with Tharros Strike and killed all at once with one slide attack.

Archon Shards
Two Cast speed shards is MANDATORY to speed up the cast of paralysis and tharros strike. If no shards, it is highly recommended to drop [Stretch] to [Natural Talent].
Put the Remainder into Energy Max shards

PLAYSTYLE

1. Activate hysteria and Warcry. Getting kills will prolong warcry basically indefinitely.
2. Tap 3 to group enemies with [Prolonged Paralysis]
3. Tap 1 to full strip grouped enemies with Tharros Strike
4. OPTIONAL: Switch to primer (using switch weapon button or aim button) to prime enemies and switch back to melee (with quick melee button) and kill enemies
5. Slide attacks have very high damage multipliers and hit all grouped enemies multiple times (6 x 300% multiplier). Alternatively, [Prolonged Paralysis] also opens enemies to ground finishers (just tap melee on paralysed enemies) which deal MUCH more damage (6 x 2000% multiplier), but don't hit as many enemies or as quickly.

BUILD SPECIFICS

Duration
Duration doesn't really matter here since channelling cost of hysteria can be minimised with maximum efficiency, warcry can be extended infinitely with eternal war as long as you get melee/talons kills and Tharros Strike/pillage/fireblast all work fine with low duration.

Efficiency
We need to hit 190% efficiency with max ranked [Streamline] and efficiency in order to hit the 25% channelling cap with negative duration. This allows you to stay permanently in hysteria without running out of energy.

Range
High range with Overextended +/- [Stretch] is required to scale the range of [Prolonged Paralysis] to approximately 23.5m and Tharros Strike to 21.15m. This means you can pull enemies close to you and hit more enemies than Tharros Strike would originally allow,.

Strength
Tharros Strike requires 200% str to full strip in one cast or 164% str to full strip with [Corrosive Projection] in Aura. We need Transient Fortitude, Power Drift and Molt Augmented to offset Overextended to hit 170% for the full strip threshold.

Aura

• Corrosive Projection is used to reduce full strip threshold.
• Steel charge is good for saving mod capacity/forma and provides a small boost to talons damage.
• Swift momentum is great for maintaining combo duration
• Growing power also slightly boosts talons damage and warcry speed boost
• [Enemy Radar] to improve positioning

Exilus
[Primed Sure Footed] is ideal, but handspring is an alternative.
Preparation is also good so you start off with full energy

Arcanes
Energize - to maintain energy to stay in hysteria
Fury - boosts melee damage after crits, with will be super common

HELMINTH OPTONS

Armor strip
Any armor strip is useful for scaling Valkyr Talons raw damage against armored steel path enemies eg grineer/corrupted.

• Tharros Strike: works well since it has a short range but [Valkyr] is melee anyway, full strips both shields and armor in one cast with low strength threshold, works on acolytes and demolysts and is cheap to cast
• Pillage: radial but line of sight with huge range, requires alot of strength to full strip (400% without [Corrosive Projection] and 328% with), or multiple casts otherwise to strip. This also cleanses status and provides shields, both of which are kind of useless in Hysteria but does have some meme benefit to Paralysis which converts shields to damage.
• Terrify: radial AOE with large range and no line of sight, full strips at only 167% str (or 137% with [Corrosive Projection]) BUT makes enemies run away from you, meaning you need to chase them down to kill you. You can somewhat overcome a bit of this by using grouping [Prolonged Paralysis] but the range of terrify is much larger than paralysis (approx 35m vs 23m) so you will often end up scaring away more enemies than you can group.
• Fireblast: max strip is 75% so always requires two casts, but gives bonus heat proc for [Condition Overload] and knocks enemies down

Silence
Against infested, you will want to use Silence to block ancient disruptors since they will take all your energy while you are in Hysteria. You may want to add more duration by replacing [Fleeting Expertise] with [Constitution]. This also prevents Violence from dispelling your warcry.

Nourish
Nourish is another excellent subsume that provides bonus Viral damage to claws and significantly increases energy gain from orbs, basically actiing as a replacement to arcane energize. You can drop [Streamline] for [Narrow Minded] in this case to prolong the uptime of Nourish.

ARSENAL

Valkyr Talons
See here for valkyr talons builds:
With armor/shield strip, run raw Viral for spin to win: https://overframe.gg/build/499828/valkyr-prime-talons/viral-talons-pure-slide-for-armor-strip/
Without armor strip, run raw corrosive for Grineer/corrupted: https://overframe.gg/build/241532/valkyr-prime-talons/valkyr-prime-talons-red-crit-corrosive-grineer/
Without shield strip, run raw toxin for Corpus focused build: https://overframe.gg/build/241635/valkyr-prime-talons/valkyr-prime-talons-red-crit-toxin-corpus/

Gladiator Statstick
Valkyr also needs a pseudo 'stat-stick' to carry gladiator mods to further boost crit chance.
You can use ANY melee weapon you like as long as you put the three available gladiator mods on - [Gladiator Vice], [Gladiator Rush] and [Gladiator Might].
You will NOT be using this melee to attack or build combo, since [Valkyr Talons] cannot share the combo counter with your melee (it reduces to zero upon deactivation).

Primer
A primary primer like [Cedo] or secondary primer such as [Kuva Nukor] andepitaph are great for providing an outside source of status effects to boost condition overload on Talons. Note, if you use fireblast, you will have a free heat proc, so you can switch the heat element on nukor/[Epitaph] for electric instead. You can then end up with between 5 to 9 elements affecting enemies, meaning talons damage can be boosted by between 400 to 720%. Here are two primer builds:

Kuva Nukor: https://overframe.gg/build/235421/kuva-nukor/kuva-nukor-primer/
Epitaph: https://overframe.gg/build/235422/epitaph/epitaph-primer/

Companion
You can put [Seismic Bond] on any companion (ideally [Dethcube] with [Helstrum] to generate orbs and prime, or [Diriga] for priming) to give free 30% efficiency, allowing you to swap [Streamline] out for [Augur Reach] or [Primed Flow]
