You channel your patronic powers through the most dangerous, cutting edge technology available to you – the firearm. Others might call this a foolish notion – why use a gun when an Eldritch Blast is simpler and more reliable. Simple answer – why not use both? Despite the reputation as old fashioned, traditionalist, and mired in the past – witchcraft has existed by moving along with the times. Eldritch gunplay is simply the next step of it's evolution – and after all, what else says "bubble bubble, toil and trouble" like exploding sulfur?
