A note on how skills work as we get started.
When rolling dice you are trying to get under the skill value, which is usually equal to a stat (for Broad skills) or the Stat plus skill level (for specialty skills).
You always roll 1d20 which is the control die, and usually another die called a situation die. Bonuses and penalties to the roll are not added to the control die or result of the dice rolls. If I say there is a +1 step penalty, that is not +1 to the d20 roll. The step progression chart shows that each step has a die code associated with it:
-1d20, -1d12, -1d8, -1d6, -1d4, +d0, +1d4, +1d6, +1d8, +1d12, +1d20 ...
Depending on the skill you start somewhere on that line. For broad skills the default start is +1d4, for Specialty Skills the default start is +d0. So you have to roll Awareness - Perception. If you have the Perception specialty skill at 1, and a WIL of 10, you roll 1d20+1d0 trying to get 11 or less. If you don't have the Perception specialty skill you can roll on the Awareness broad skill rolling 1d20+1d4 trying to get under 10. A step penalty means you move on the line in the bad direction: from +1d4 to +1d6 for example. A step bonus means you move in the good direction, from +d0 to -1d4 as an example.
Perk checks are essentially Ability Score checks, the base situation die is +1d4.
