No forma leapfrog dagger to help with [Ivara] prowl movement through heavy slam attacks. High status chance and radiation to aid in shield regeneration. [Gleaming Blight] helps keep up your energy while also providing necessary status chance. [Life Strike] provides some healing. [Dispatch Overdrive] boosts base movement speed which works in prowl. High range to make regular heavy attacks viable too.
Note 1: This is not intended to be a high damage weapon. It's a very niche tool that only really helps a prowling [Ivara]. I do consider it to be essential on a prowl [Ivara] build.
Note 2: swap away in grineer spy vaults. Blight procs alert sentries.
