If a hero has a Skill that could reasonably help in a Trial they're about to undergo, they might gain a great advantage! Using a Skill might cause a Trial (or Trial stage) to become much easier.
At the beginning of a Trial (or the beginning of each Trial stage), roll 1d6 and consult the following table for the modifier received toward success in the Trial (or stage).
Skill rank -2 (minimum 0)
Skill rank -1 (minimum 0)
Skill rank +0
Skill rank +1
