To be noted: I am a Loki main since the beginning (2013), where Loki was even an option to choose from the first 3 starter (Pokemon rip-off), and I must even say, I can sure minded replace the stealth-throne with [Voruna]. Constant invisibility rendering almost any AI useless and dumb, insane amount of damage due to status stacking like crazy - even on bosses e.g. here and has the utility (passives) that everyone would die for: NO FUCKING KNOCKBACK/KNOCKDOWN EFFECT! Fml... No one wanted that effect on any AoE in the first place, DE (and now self-damage will return + knockback/-down is here to stay)! Same goes for the dispell effect after falling through the ground due to your mesh-collision-scripting noob.

### Main Guide:

A "Werewolf", which acts more like a mystic OP Dragon.
They should change their declaration, as she has nothing to do with a real wolf / werewolf, tbh.

I call this build the "[Steel Path Annihilator]."
Why you ask? It originates from my older "[Loki - Marked for Death]" build, but doesn't even has the "[Marked for Death]" subsume!? Because like that. It doesn't even require [Marked for Death] and is even stronger than that. Requires no LoS, neither for the weapon nor for the ability combination.
And is way more effective people play and show builds of her currently with nonsense "high HP, Gloom, armor and stuff" builds.

Her combination of [Terrify] and [Fangs of Raksh], with an AoE melee or firearm weapon is everything you need for this entire kit to work in the most OP way you could think of.

ATTENTION! [Overextended] is 3/5 due to my own personal archon shard synergy! You may want to pay attention to this more carefully for your own build capabilities!
Terrify needs to strip off 100% armor - thus you will need to min-max Ability Strength with (Archon Shards and) [Overextended] to an [Extend] °badum tss° where it reaches its 100% armor strip threshold. Otherwise, the combination might be half as effective on e.g. pesky Eximus units. You can also wait for Molt Augmented to [Reach] the threshold during your session. There is a potential 60% power strength increase in it.
If not owning any of these, [Molt Augment], [Madurai] 40% Strengh Buff and/or any PWR STR [Archon Shards], then you may be better off replacing [Overextended] with something else instead.

Archon Mods. [Archon Stretch] is not a must have. It is another tiny layer of adding an additional energy [Regen] on top of your already powerful third ability (dropping health orbs (regular melee) and energy orbs (headshot) upon kill). Each time you use your second ability and apply any status effect, you will trigger any Archon Mod which has the "applied XYZ status on enemy / killed enemy with XYZ status effect"-condition on it. Voruna is capable of triggering almost all Archon Effects (exceptions made to healing - [Archon Intensify]). And not all of them are viable at all, imo. [Archon Vitality] for example works perfectly on [Ember] (Prime), but will make no sense on [Voruna] due to applying only an additional heat proc to the 10 stacks you already applied via skill, resulting into 11 heat procs, not 20!
So, you could free up some mod capacity by replacing [Archon Stretch] with its regular one, [Stretch].

Use any Arcanes as you see fit. No need in [Arcane Energize] (3rd ability compensates) or [Arcane Guardian] (you will never get a direct hit due to being invisible), choose freely whatever you like. I am still experimenting.

I am strictly against recommending weapons like [Venka Prime], [Kronen Prime] or any other "1 hit = one to few kills" nonsense firearm and melee weapons.
The reason for that is: You can literally stay invisible the entire time, when spamming (either per button press after each attack/fire, or, more recommended, via macro script) your first ability, [Shroud, of Dynar] and execute massive amounts of enemies with AoE weapons instead of regular short-melee types.
When attacking with the [Xoris] or any other good AoE weapon (take [Xoris]. Don't think about [Glaive Prime]. It got nerfed to oblivion, no proper slash procs anymore. RIP) you will be less likely wasting time and energy to recast your first ability after each minor/unimportant kill.
If, for example, you are up to using a Claw weapon, you will spam your attacks quite often on each enemy, so that you will literally drain your energy pool with recasting (especially via macro) your first ability to stay invisible.
And no, the critical buff (3.X times more critical damage and more status chance) from the first ability is not worth it compared to the stealth damage multiplier.

Passives are pretty variable. I often mix-match the first (increased parkour velocity) and second passives (immune to status effects like toxin, electric, stagger, etc.) but I would recommend using her second passive due to AoE weapons may blast you off your shoes - which honestly isn't happening quite reliably due to [Shroud of Dynar] avoiding being staggered/knocked off during cast time before a blast is reaching and affecting you.
Third and Fourth (not available due to subsumed helminth ability on 4) are, imo, not worth bothering with.

As a proper use case, equip a [Dragon Decaying Key] (reducing shields). Why you ask? Simple: You can shieldgate easily with [Terrify] due to [Brief Respite] filling your shield pool over 100% with a single cast. So, take advantage from this! There were no Augur Mods included in my demonstrations; Shields got replenished easily. Who needs [Ulfrun's Descent], when you can cheat death more easily without a freaking cooldown. Amiright?!

• First of all, cast your third ability [Lycath's Hunt] to get a steady supply of health orbs upon melee kill. [Equilibrium] is essential, you may get why. Everytime you get an health orb, you get your energy filled. Guaranteed.
• Secondly, always stay invisible with [Shroud of Dynar]. Keeps you out of sight and also gives you the proper stealth damage multiplier, and makes you move faster in that regard, too.
• Upon reaching a cluster of enemies, cast your subsumed fourth ability [Terrify] to pin enemies in place (they won't run away due to not knowing where your warframe is located at, IF they didn't see you before. Quality AI-smartness programming of DE) and strip off their goodies.
• Then cast your second ability [Fangs of Raksh] more than once, due to the randomized status imbuing.

Now shred them to dust with your weapons at once and hunt down the next pack of grineer/corpu/infi skoom!

Best regards and happy hunting, Tenno!
