((so sorry that this took so long to make and I also apologize for only having five. I figured I had to get something out oh, but I do plan on making more once I get within the right mindset. But, anyway, here you go, as I promised. Eldritch Invocations. I will come up with more, I promise, but for now, here's part 1, I guess))
