A test or check, also sometimes called a throw when using dice, is a common type of resolution mechanic that uses randomness to determine a character's success or failure when performing an action or task. In the language of the IIEE model of resolution, tests apply judgemental resolution to the character's intent and initiation of the task (they are assumed to happen merely because the player says so), and random resolution to the execution of the task. (The final effect of the task may be determined in the test itself or a separate part of the mechanic, e.g. a damage roll for an attack.)
Tests may be either simple or complex. A simple test is determining the outcome of one action. For instance, a character might try to pick a lock, and determining whether and how quickly it was picked is a simple test. A complex test involves multiple steps. For instance, hacking into a computer might involve first gaining access, then overcoming the system's security, locating a file, and then removing evidence of the intrusion. Whether a test is simple or complex depends on the system; in some systems, hacking into a computer might be a simple test of computer skill.
Examples[]
Common types of test in role-playing games include:
- Attacks (specifically the to-hit element): Does the character hit their enemy?
- Saving throws: Does the character avoid damage or other negative consequences?
- Skill checks: Does the character successfully apply their knowledge or training to the situation?
