====== Advantage probabilities ======
~~NOTOC~~

There are two types of [[combat#advantage]]
  * For hit rolls and ability checks, you roll twice and take the higher result for advantage, or the lower result for disadvantage
  * For skill rolls, you roll an additional 3d6 for advantage, or you remove 3d6 for disadvantage
