It's VERMINTIME! with Sienna Fuegonasus starring as: Pyromancer

This video cost me much blood, sweat and tears. Tears of joy! I had to practice this build a lot to make it work in a Vermintide 2 Semi-Solo environment. I hope the wait for you was worth it. Personally I am having a blast with this build when playing with a group.
Oh, and I also hope you enjoy the video as well. :)
