Checks are the basic interractive function of the game, and you will be asked to perform them when the gm prompts you to. A check is the numerical value of the result of the d20 after being modified by all of the applicable modifiers. Checks inheret the classification of all checks in their broader category when looking to determine what modifiers will apply. For example, an attack action requires an accuracy check, in the martial skill, with a weapon. Any modifiers to checks within these parent categories will also apply to the accuracy check of the attack action.
