Joe has implemented what I think is a neat system to enhance testing. At the GM's discretion, a certain test can be done at advantage (draw 2 cards and keep the best) or disadvantage (draw 2 cards and keep the worst.) I believe the theory is sound and that it should be included in the new rulebook, but there are a few aspects of it that need to be clarified.
What determines if there is an Advantage or Disadvantage? Currently it has just been Joe deciding on the spot, and truthfully he does not have enough knowledge of every characters background to determine whether or how a test should be modified. Should characters describe their specializations more to ensure a more even interpretation of whether a test should be modified?
How does Advantage/Disadvantage interface with abilities that allow multiple card draws? For instance if you are under the effects of the ritual Mark of Fortune which allows a redraw on a failed test pull, would you pull twice or just once for your redraw when working under Advantage/Disadvantage?
Would this work like the 5E rule it is borrowed from or do multiple Advantages/Disadvantages stack? Would one Advantage cancel out multiple Disadvantages?
