Game Settings: Dice Roll Optional Settings - Genii-Locorum/brp GitHub Wiki
Enter Difficulty Values - rather than selecting the difficulty level from a drop down menu you enter the difficulty value as a figure (e.g. 2 is the equivalent of easy, 0.5 = difficult). Please note that in this case Characteristics are not multiplied by 5 as a default, so if you want an average roll for STR then you need to enter 5.
Allow Impossible Rolls - this adds "Impossible" as a difficulty level when making the appropriate dice rolls. The chance of success is always only 1%
Always make Resistance Rolls - when active the chance of success is always in the range 1%-99% so there is always a 1% chance of success or failure.
Detailed Resistance Rolls - when making resistance rolls rather than a simple Success/Failure result you can have Critical, Special and Fumble results as well.
