Advantage/Disadvantage

Under certain circumstances, usually resulting from previous planning or exceptional role-playing characters will receive Advantage. Advantage works as follows:

When a player rolls an ability test, but before the GM announces the results of the test, the player may use their advantage to re-roll the ability test and keep the higher result.

Disadvantage, usually resulting from poor planning, rushing into a situation or some pre-planning on the enemies part, works the exact same way as advantage, only that the worse roll of the two is kept as the result.
