[Titania Prime] comes with innate polarities that allow a relatively complete build to be made with no forma!

Cast razorwing after picking up energy orbs to increase ability strength by 50%.

Get a kitgun with Pax Bolt to allow for 30% efficiency and 30% strength on your next razorwing cast after a headshot. Make sure to max it out to give you the most time to switch into razorwing.

I put arcane velocity and precision on [Titania Prime] to enhance her [Dex Pixia] damage and fire rate.

I personally don't feel that the benefit in terms of fire rate and movement speed given by [Razorwing Blitz] is worth sacrificing a mod slot for, especially when [Energy Conversion] and pax bolt give ability strength (and efficiency for pax bolt) and arcane velocity gives fire rate.

If you are going to use forma, add an aura forma and switch to [Aerodynamic] to get more damage resistance in razorwing. In the meantime, [Growing Power] is a great replacement as it gives yet another opportunity to have increased ability strength while in razorwing.

[Aviator] is really popular, but i find [Preparation] to be a more practical exilus mod as it gives you the option of immediately casting all of your buffs as well as razorwing. The buffs make you pretty much invincible anyways as long as you don't stay in one place too long (especially while in razorwing) and energy drops from enemies are plenty to keep you full once you have your energy up.

If you like this no-forma build, but want to add [Razorwing Blitz], enough range to make [Titania]'s other abilities more viable, and more health, then click here!

Once you decide that the Fairy Queen is worthy of your forma, this build is the one that I have found to be most enjoyable:
