LITERALLY RUINED FOREVER

Seriously though, god damn. Good work.

My only immediate issues with it are the diminishing returns (I usually handle them by making each point worth slightly less than the last, instead of some arbitrary number harshly cutting down on it), but we'll see. As for the other issue...

I seriously doubt 3 points per level is enough, especially with two new stats added to the fray. Four sounds a lot better to me.
