Disclaimer: I am relatively new to making builds and am not saying this is the best one. Any suggestions would be appreciated!

Alrighty then, this is [Gyre]. [Gyre] (at lest I feel) is one of those rare frames where all the abilities work really well together and [Flow] really well. I've tried my best on this build. It's probably a bit overkill and it costs a lot of forma, but, there is no kill like overkill.

Here is the ability [Flow] I use for Gyre:
1. Cathode Grace
(1a) Kill some enemies to keep Cathode Grace up.
2. Arcsphere
3. Rotorswell

Helminth/Coil Horizon:

Coil Horizon is a toughie. It is a good ability don't get me wrong, just feels a bit wonky. My suggestion is to throw it down an then quickly throw your Arcspheres on the new meatball to buff up all your abilities with the electric procs. Coil Horizon is definitely the ability you would want to replace with helminth if you want to. I would suggest swapping Coil Horizon for Pillage, Larva/Ensnare or even Resonator for some Survivability. Breach Surge is also always good for extra DPS.

Aura Mods:

I like Breif Respite in the Aura slot here, but, it does require another forma. In the end it's up to personal preference.

Exilus Mods:

I prefer [Power Drift] for that extra little bit of power strength and some knock down resistance but if you would like to just never get knocked down you can use Primed Sure-footed

I think that's about it. Again, if you have any suggestions I will definitely take them into consideration and update the build!
