Skill modifier = ability modifier + proficiency modifier +
circumstance bonus + conditional bonus + item bonus +
circumstance penalty + conditional penalty +
item penalty + untyped penalties
Just found out the important part of this, pg 292. Multiple item, circumstance, and conditions bonuses do no stack. You only take the best one of each. The penalties do not stack either you have at most one circumstance bonus and one circumstance penalty, one condition bonus and one condition penalty, and one item bonus and one item penalty. That's interesting.
