Aptitude rules

This world has magic and science as conflicting forces. Each has special unique rules how they interact with the world, creatures and it's opposing force.

Levels in certain classes add an aptitude point as well as feats, items, features and backgrounds. Magical and Technological aptitude are polar opposites and balance each other out. For example for you have 3 points magical aptitude and 1 point technological aptitude it balances to 2 points of magical aptitude. You can get up to 10 points of aptitude.

For game mechanics Ki, Mist points and Psionics are not considered magical or technological.
