Chaos and Law affects the theme of the last true chapter and the way that Loki will rule afterwards (I presume....only doing Law so far). They change based on conversation choices made by Loki during Story and Call scenes. You must achieve at least 20 points in either to get into the last chapter, else you get the "normal" ending (a bad ending but a ending regardless not a game over). Getting 20 at least in each gives you the ability to choose between Law/Chaos/Normal, while going above 30 Chaos forcibly locks in Chaos Route.so for being a dumb, but what is all this talk about chaos and law? seems you get different endings depending on this values, but what causes them to change? also is there a way to check said values?
You can check your current points by looking at the Call screen, they are labelled "Reign" (Law) and "Conquer" (Chaos). You can always save-scum each decision you make in the plot, check the result and reload to get the points you want just like you can with affection. It's advised not to cheat these values, you may mess up some of the checks the game runs so don't modify them by cheat engine.
