Above is my (7 Forma Boltor Prime Corrosive Build) I added 7 Forma (not required) for the build. I added the 7 polarity's so I could adjust it different ways and test different mods and damages. I never said 7 Forma was an Exact requirement. I am really sorry... I see I need to be 100% specific or risk getting destroyed and picked apart. Honestly I was just enjoying Warframe and the Boltor Prime.
