When you make an action roll, the roll will have a Difficulty —the number you need to reach or exceed when you roll. Often, the GM sets the roll’s Difficulty based on the situation and how effective your approach might be. Some features provide this Difficulty in parentheses after the listed roll, such as an Agility Roll (13) or a Spellcast Roll (10). If you’re making an action roll against an adversary, the Difficulty is found in their stat block.

The GM can choose whether to share the Difficulty of an action or not. Even if they don’t tell you the Difficulty, they should make any potential consequences of your actions clear (unless the consequences aren’t something your character would reasonably know). For example, “You’re putting yourself in melee with this guard, so you might take a hit in return”, or “If you fail this jump, you might not make it to the other side”.
