She is my main, a beast for speedrunners and the rest.
Use her in everything, when I say best in everything I mean from open worlds to bosses like exploiter.
Everything on her kit just costs 10 energy too, which is amazing.
Hope it helps you, enjoy.

* = Since Magus Elevate exists, I don't use it even for healing so I can't recommend anything special. I think you'll find a better build than mine that you like somewhere around here.
Arcane Pistoleer/Arcane Velocity instead of Arcane Energize, if you can go without that Energy boost. Also Arcane Guardian is a great choice for survivability. Some have used Arcane Avenger too. Go with what you like best.
Have Aura Forma on her (or just Forma her if you want) so you can switch a more surviavable build whenever you want. Just change Growing Power with Aerodynamic and she becomes the Dodge Queen, with her Thorns & Dust, or a 250 Speedster Beast by changing Aviator with Power Drift (you can do the Speedster without anything extra). If you want to push it more and dont want the amazing spped buff for some reason, consider having a Forma for Agility Drift instead of Razorwing Blitz. Also sidenote, DO NOT USE Coaction Drift, as it does not work with Growing Power (or Power Donation for that matter), so it is useless (or as the wiki says it "(Coaction Drift) does not work with Growing Power nor Power Donation"). And remember to proc Growing Power before the cast with a weapon.
If you want to have even more survivable than this, consider maybe putting Pillage on her 3rd and for the cherry on top, there is always Arcane Aegis.
Do keep in mind that the build is a bit tight on Energy, so if you want more flexibility, remember that Primed Flow exists and you can have it in place of Adaptation (with the right Forma ). This would allow you to even run builds like a Thermal Sunder one for fast exterminates and fisures, since you go against low level enemies.
In case you dont have an Umbra Forma on her yet, just use a Forma on the Exilus Mod of your choice and instead use Steel Charge.
