+### Ability Checks
+
+Simple tasks are assumed to succeed. If the task is dangerous or complicated, roll the dice for an Ability Check.
+
+-   For most checks, roll a 20-sided die (d20) **at or over** the specified Difficulty Class (DC) for that ability.
+
+-   For harder tasks, add 1-4 to the DC before the die is thrown.

+-   Some results are special:
+
+    -   A natural 20 represents a critical success: the check automatically succeeds, and often includes a bonus for the roller.
+    -   A natural 1 is a critical failure: the check automatically fails, and the attempt often causes an additional complication or challenge for the roller.
