Hi. Love the game. Core Rules needs fixing though. I'm a D&D GM and I do a lot of math work involving rebalancing and fixing of core rules.

Most times in most games, I ignore it so I can enjoy the game, but I had a bunch of heavily plated characters who got their asses handed to them by a couple of wolves in Original Sin.

Something wasn't right about that.

I wish to mod the rule system itself. But need help being pointed in the right direction (besides the mod section of the forums).

How does one access the rule system itself for modding?
