Problem:
>!Explosive Concoction is a cool skill, but its elemental. I want a poison version!!<
Solution:
>!Original Sin!!<
Hey! Shoutout to CaptainLance9, who said hed give me a carry for the Original Sin ring if I promised to make a cool build with it. After much deliberation (and one semi-failed build with Kaom's Primacy) I settled on Explosive Concoction: an attack based projectile with huge flat ele scaling that I could turn into chaos and use to poison... a sort of Poisonous-y Concoction.
The far and away best use case for this ring has been solved by our buddy Subtractem, who uses phys->cold->fire->chaos with heatshiver/expeditions end. IMO there is no rivaling this method of added damage (and Kaom's Primacy WAS NOT it), so I decided to make something entirely different. My goal was to make a build that, without the Original Sin ring, couldn't function.
I had a lot of fun with this build (and video), so please enjoy! There are even some bloopers at the end. :)
