 ====== Advantage probabilities ======
+~~NOTOC~~
 \\
 There are two types of [[combat#advantage]]
-  * For hit rolls and saving throws, you roll twice and take the higher result for advantage, or the lower result for disadvantage
+  * 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
