The only thing I see really wrong with this thread is the terra blade thing (again, agreeing with Bacon here). You shouldnt have to use a terra blade to craft something else. Just leaving it as an ice blade that doesnt shoot beams might be ok, just as a side sword kind of thing. Though I still don't know where that would fit in progression...
This is kinda off topic, but
What about Tobbvald's RIA? I know it hasn't succeeded yet, but it got a ton of support even from you
OT: make this sword a little less powerful and use like the frostbrand instead of the terra blade, and I may support this. Also: what does the snowy sword drop from?
