So, we want a specific set of abilities that allow something that doesn't exactly mesh with the base class? Why don't you just create a Mercer-type prestige class? I don't want to overload the base class with more features at this point, and forming weapons isn't much of an epic-level power.

I've been thinking about the Epic Ozodrin, trying to figure out what else the class would actually find useful at epic levels. I have some ideas, but I am still working on them.
