Skill Checks

are performed when the DM asks for one in response to a character attempting some action that requires skill by the character. It is done by rolling a d20 (or 3d6 in some cases) and adding the character's corresponding bonus for that skill, which is determined during character creation.
== Criticals ==
If the roll is 1 on the die (before skill bonuses), this typically means a "catastrophic" failure on the part of the character that the skill check was rolled for. A 20 on the die means a "critical success" that typically goes as well as was feasibly possible for the character.
If the player is rolling 3d6, criticals are on all 1s or all 6s.
