This build is designed to make the Purgator 1 function similar to the Sporothrix sniper rifle gas builds. Hard-hitting weakpoint damage that will leave deadly gas clouds lasting 12 seconds each. While quite effective in general, it shines in high-density missions with choke points, making the best use of Cannonade's punch through and gas. This setup is designed to work entirely on its own so you can mix and match with many warframes for incredible synergies. I've personally been having fun switching to the [Scyotid] and pulling enemies into the lingering gas clouds as an example. Give this build a try and have fun, kings and queens!
