In the game itself, I think you can only see the descriptions in combat, which isn't very helpful if you're attempting to plan fusions.
There's also Zeed. It doesn't take mag either and can learn almost any type of skill set through fusion.
thanks for the list. at least it gives me a rough idea.
Zeed? never heard of him. Or do you mean the Zoma fusion? Haven't tried that yet...
