Thorn + Dragon's Breath = Claw of the Ahamkara - Exotic Solar Hand Cannon. Unique perk - Thirst of Stars: Projectiles over-penetrate targets and trigger a Solar DoT. Enemies killed by this DoT will trigger a solar explosion, and any targets damaged by the explosion will have the DoT applied to them. Simple concept, you shoot, it causes a damage over time, just like Thorn. The difference is the explosion mechanic, which will only proc if they die by the DoT itself, which would balance it. Killing them with actual shots when it's applied will do nothing. This explosion then applies the same DoT to nearby targets. It won't be strong enough to kill most targets outright, but it'll do enough to cause a bit of mayhem and, considering how often I get a kill with the DoT itself in PvP, it would be fun to see how it makes an opposing team wary of their teammates.
