Skill Checks

When a player wants to interact with the world, its creatures or other humans there is often a skill check involved. Below we’ll take a deep dive into all the skills in the game with examples and difficulty ranks. In all cases, the player will roll a 1d20 and add their skill bonus to the result of that roll.

Determining Base Difficulty

As a GM you have a lot of flexibility so the exact difficulty you choose is up to you and how challenging an experience you want to have for your players. If you’re playing with younger players and want an easy experience then jumping over a 5′ ravine could require a check of 10, or for a more challenging experience this could require a check of 20.

You can also consider that the same type of check may increase or decrease in difficulty depending on the exact scenario. These modifiers keep the game more dynamic, especially with more experienced players. For example, the players have previously accessed a computer terminal to over-ride a security door. They know that they were able to succeed last time with a result of 12. Coming across another computer terminal later in the game, they expect they can do the same, only this time the computer terminal requires a password! In the first example, the required check was only 10, but since this terminal requires a password, the check now requires a result of 30 to succeed.

As a guide, below I have given example actions for each skill and recommended difficulties for distinct types of players. For both new or young players using the simple column is recommended. For experienced players using the advanced column will provide a more challenging environment. These are only examples, so keep in mind that you as a GM have the power of flexibility!
