Vitality is interchangeable with adaptation or rolling guard. If you don't use projectile weapons for hunting with zephyr and don't care about compatibility with my other build, replace jet stream with whatever you want My suggestion if you do this would be to keep vitality and replace jet stream with either rolling guard or adaptation, depending on whether or not you have a decent harrow in your squad. In order to fit both of my builds an aura forma is required unless you want to use different auras than I do.
I chose arcane fury because I use redeemer prime or glaive prime while hunting with zephyr. Feel free to replace it with whatever you want.
