Ability Checks

The GM calls for an ability check when you attempt a task (other than an attack) that has a chance of failure. (77) For each check, the GM decides:

Your ability check = d20 + relevant ability modifier + proficiency bonus (if any) + other bonus or penalty.

  • See reasons for having advantage or disadvantage

  • Add your proficiency bonus if a skill applies and you are proficient in it; otherwise roll without the bonus.

You succeed when your ability check total ≥ the DC. Otherwise you fail.

If your effort is opposed to another’s, use the contest rules.
