Initiative is a trait calculated by adding your Mental and Physical attributes together, then subtracting your Size. Smaller characters thus have higher initiative than larger characters. This is rolled along with a 1d12. Every 10 points on the roll is one action you may perform in any given round, these occur starting at 1 (IE. 1, 11, 21, 31, ect..). Higher numbers go first and usually you use all of your actions at the same time on your init turn.
