Well, ir's obviously not balanced for vanilla. But I had talked to the quite a while ago now. And they did try to walk a fine balance of being useful and fun, but not too over the top. They apply limitations where it makes sense for them.
Especially since there is PvP.
If you liked Hex Casting, or even Psi. This should be right up your alley. It's also less tedious than either of them I would say.
Yeah that mod is really cool. The magic writing system is fucking awesome.
Even cooler than Hex Casting in my opinion (which is already super cool).
And It's quite a bit easier to work with since it's not stack-based and that you can edit different parts of you spell/program at any point.
