Trying Again and Pushing It
An unsuccessful Skill Check doesn’t necessarily equate to outright failure, but it does mean that you have failed to accomplish your goal. If you do fail a check, you cannot attempt the same activity again unless the narrative circumstances have changed (e.g., time has passed, you have new gear, a different approach, or additional help, etc) or you Push It.
As long as a Skill Check isn’t Risky, you can make a second attempt to achieve the goal of a failed skill check in the same circumstances. This is called Pushing It. However, if you do this, the skill check immediately becomes Risky. If the situation is already Risky, you can’t push it further unless the GM allows it, in which case the skill check becomes Heroic. A Heroic check can never be pushed further.
