Not the most inspired thread title, I know. And it's probably fairly cliché as a first post either, but I've got an itch to scratch and questions on how to scratch it. To put an unnecessarily long story short, I have an idea for a particular type of RP of Arcanum I want to do and I like to make custom backgrounds designed around the character I want to make. Usually I don't care about balance as the point is to have fun, but this time I want to try something new and it's fairly important that the background be as close to objectively balanced as possible. The background itself is as follows: Eccentric Inventor You love technology and have tinkered with it, to the exclusion of everything else, since you were a child. You developed a keen, inquisitive mind (+4 Intelligence) and a natural understanding of machinery (+1 rank to repair and traps), but your limited interaction with people has left your social skills with much room for improvement (-2 Charisma and -1 rank to haggle and persuasion). You also have a tendency to wear your latest experiment on your shirt, so others find you more repulsive than you are (-20 Beauty reaction). It's meant to be a somewhat milder, technologically inclined version of Only Child. Also I'm not entirely sure what the difference between Reaction and Beauty Reaction in Arcanum Factory is. Also also, when I say "rank" I mean an entire skill level. Any and all input will be greatly appreciated.
