Endgame [Saryn] build.
By far the best DPS for survival missions and ESO.
[Transient Fortitude] can be swapped with Umbra Fiber if you want even more survivability. This will however take away a good bit of power strength.
A melee weapon with good range and status as well as, healing return and condition overload is very good for this frame.
Arua Froma is there to giva more flexibility.
Arcane's can be replaced with whatever you prefer. Guarian is there to supplement for the missing armor mods, and Energize is there to help keep you're energy up.
