It will apply some small patches to the vanilla MCP source code, giving you and it access to some of the data and functions you need to build a successful mod. I may also try this and Content Tweaker before I attempt to use Mcreator. Since, I have almost no modding skills and I imagine the learning curve to be steep, I'm going to try an alternate route by using Craftweaker. So, far it's our favorite magic mod because of that. This mod does feel like an attempt to implement a DnD like spell system. I think you have your work cut out for you.
A fellow DnD fan! I checked out that link.
