A general use type of build for [Titania Prime] when paired with a Good pair of Pixias will melt and do just about every type of content in Warframe.

BUILD

For the Build use any type of Aura you want with some forma you can use any of your favourites like [Corrosive Projection], [Brief Respite], [Steel Charge], and even [Enemy Radar]
I have chosen to focus on Strength and Duration for this build because I wanted to, as much as possible, keep Titania's 4 toggled at all times. With this in mind feel free to;

• Replace [Overextended] with another mod of choice. While not needing that much range to effectively play [Titania] I wanted to keep my range atleast on the positive side to get as much off my 4 as possible while also being able to help teammates in proximity with Energy economy from Nourish.

• Replace Streamline with another mod of choice, use this slot as a quality of life slot that is extra flexible for different build types.

• For the exilus slot use [Preparation] for energy on spawn, Primed or non [Primed Sure Footed] for extra insurance especially when running [Titania] with Zenurik or if you're comfortable with using Energy Pads on every start of the Mission.

Edit: I went with [Equilibrium] rather than [Streamline] for better survivability and energy economy on the long run. This may cost you 1 or more forma when running something in your exilus slot but i've yet to decide best in slot since i still refuse to just run [Primed Sure Footed] on every build :(

For the Arcanes, feel free to replace both Arcanes with any of your choosing, I recommend Arcane Energize especially if you wont run her with Nourish, Molt Efficiency if you want to get that Duration from somwhere else other than [Narrow Minded], Molt Augmented, just like Efficiency if you dont want to use [Blind Rage] for strength, and Arcane Avenger if you want to run that extra Crit Chance on her.

As for her Skills I wanted to replace Lantern with Nourish to keep up my Energy economy especially since I am running [Titania] with negative efficiency.
This can be replaced with a Tenno favourite for [Titania], Thermal Sunder for that Elemental damage and armour stripping from heat procs, or the newly reworked Tempest Barrage, when running Tempest Barrage with [Viral Tempest] this can give you a new source of AOE damage much like Thermal Sunder with very usefull status procs in a single ability, i.e. Viral and Corrosive.
