Hello there,

Introduction

[Wisp Prime], the [Ignis] fatuus, is here!

I reached up to 449% Strength (solo), without sacrificing other important stats, like Duration, or Range. Given Strength can be further increased by adding (Tauforged) Crimson Archon Shards, your Teammates abilities, Auras, Focus Schools, etc.

Your first question is probably "why I replaced her 2nd ability, not her 4th?"
Short answer?
Heat Inherit!
Wait... what?!
Well, Sol Gate deals Heat and Radiation damage ramp-up per half second to 100% up to a maximum of 1,000% damage bonus. That's a lot of damage! And I never actually used Wil-O-[Wisp]. So... Roar, and now you possess the real "portal to the Sun". Use it after you prime your enemies with HI Primer, and burn them to ashes.

Playstyle:

Alternative builds:

ROAR - Heat Inherit fun build (yup, the above one).
ECLIPSE - Cool weapon platform build.
NOURISH - Totally peaceful build, most used.

Attributes & Abilities:

449% Strength, without anyone's help, buffs, Shards, just you, alone. That's a lot! But why? I'm glad you asked. Let me give you some numbers: +1347 Health added to your base Health, 134.7 Heal/s, +89.8% Movement Speed and Attack Speed, also +134.7% Fire Rate, 8.98x Damage Multiplier, with 89.8% Radiation Status Chance, up to 6 735 Beam Damage/s without any other boosts.
What about Helminth abilities, you ask? OK sure, I'll give you even more numbers: up to +898% more Weapons Damage Bonus thanks to Eclipse, +157% Damage Vulnerability for enemies affected by Sentient Wrath, +134.7% Increased Damage for you and your Teammates thanks to Roar, +116.8% more Weapons Void Damage Bonus thanks to [Xata]'s Whisper. Just a few examples of how Strength affect this build.
Those numbers can be further increased by Shards, your Teammates, Specters, Auras, Focus Schools Abilities, etc.

145% Range gives all your Reservoirs 7.5 m Radius, 22 m Shock Range for your Shock Mote, 22 m Blind Radius for your Breach Surge, and 58 m Beam Length.

Negative Efficiency should not be any problem for you, because you are not a caster, you cast Motes in place, and you take them, you cast Breach Surge when you need it, you will probably barely use her 4th ability... and you will recast your chosen Helminth ability whenever its expires.

128% Duration is well enough. 38.40 s Mote lifespan, when you leave its Radius, 20.50 s Blind Duration, and various numbers for your chosen Helminth ability.

Why no [Rolling Guard] or [Primed Sure Footed]? Well, mostly because you are going to control an entire room full of enemies with your Shock Mote, and because you are going to jump like a bunny on Heroin, because this gives you complete invisibility to enemies while you're using melee weapons and jump.
If you feel like you need one or both of those mods... feel free to add them.

Suggested Aura Mod:

For best results use Aura Forma, so that it can be changed, when needed.

Suggested Exilus Mod:

Must be unlocked with an Exilus Adapter.

Suggested Warframe Arcane Enhancements (Max Rank Description):

Suggested Archon Shards (Tauforged):

Suggested Focus School:

Suggested Helminth Subsumable Abilities:

Suggested Loadout:

Summary:

Ah yes... [Wisp Prime]. Simps can't wait for her... all thanks to her... skills ;) Skills that are very useful on the battlefield... healing, crowd control, blinding, damage buff... all of which are greatly appreciated by the rest of the team... You know what else Simps appreciate? HER ASS! Yes! Don't write nonsense here, I know what distracts you so much in this game... Her biggest "advantage" are definitely well-shaped buns and their animations while standing and moving.

Enjoy! YOU SIMP!
