This is my own build for [Rhino] for the Index and is not fully optimized (and because I do not have [Rhino Prime]). Not fully ranked mods because of insufficient endo and credits (but do it if you can). [Enemy Sense] and Vigilant Pursuit can be used interchangeably.

Edit: Replaced [Steel Fiber] and [Streamline] with the new HoD mod that increases armor and health and with [Umbral Fiber] and [Transient Fortitude] with [Umbral Intensify]. Just get an energy orb and cast Iron Skin. Don't forget to recast Iron Skin when it's getting low.
