I am still toying with his build but I am currently aiming him as a more support oriented frame utilizing his Sentient Buddies mainly. So far the main builds I have seen take a more min-max approach with duration and strength leaving out range. While it works for the sentients, I am not a fan of sacrificing so much range on his other abilities, especially when it affects the radius of his armor strip on Fusion Strike and the over all radius on Sentient Wrath.

I was not a huge fan of his Razor [Gyre] but I may still be proven wrong about that at some point as I work with him more.

Roar was a generic default to go to with testing but I also want to look at Resonator and possibly Gloom for Razor [Gyre] synergy.

The Arcanes are really just a default I use as these are often play style and persona taste dependant.
