Use with the following builds for best results:
Daikyu for Melee Only Ash
Nikana Prime for Melee Only Ash
[Helios Prime]
Deconstructor Prime for Melee Only Ash

Pure melee build using [Ash]. These builds will make most content in Warframe trivial. Why [Ash] instead of [Loki] or someone else? Because [Ash] can get combo duration using a warframe mod, which frees up a slot on your melee weapon. This build is made for full duration and efficiency to stay invisible forever, with the Gladiator Set for damage and some defense and [Rising Storm] for combo duration.
