It started as an attempt to fix useless/broken sign skills, but quickly became something more. I have plans for it's development, so it's just a first step.
Note that I'm not a fan of total rebalance mods. I like vanilla system for being unique in its own way and just want to tweak it an make it more flexible. So if you hate the system completely - this mod is probably not for you.
2CDPR: there were a lot of bugs I fixed, like broken skills. You'll probably want to fix them too sooner or later.
