Determine base difficulty of the task ("D"):
simple: 1
standard: 2
expert: 3
master: 5
epic: 8
This is the number of successes required, and the base number of d20 to roll.
Assess level of character's relevant attribute ("A"):
mediocre: 0
average: +1
above-average: +2
impressive: +3
superb: +4
This adjusts the number of d20 to roll.
The same for relevant skill ("s"), and any circumstantial bonuses ("B").
Assess attributional and circumstantial penalties ("b"), which bump up the difficulty (number of successes required).
Then roll (D+A+s+B)d20. Each d20 > 13 is a success, roll extra d20 on a roll > 18. Compare total successes, "S", to D+b.
