Skill Challenges An audience with the duke, a mysterious set of sigils in a hidden chamber, finding your way through the Forest of Neverlight—all of these present challenges that test both the characters and the people who play them. The difference between a combat challenge and a skill challenge isn’t the presence or absence of physical risk, nor the presence or absence of attack rolls and damage rolls and power use. The difference is in how the encounter treats PC actions. Skill challenges can account for all the action in a particular encounter, or they can be used as part of a combat encounter to add variety and a sense of urgency to the proceedings.
The Basics To deal with a skill challenge, the player characters make skill checks to accumulate a number of successful skill uses before they rack up too many failures and end the encounter. Example: The PCs seek a temple in dense jungle. Achieving six successes means they find their way. Accruing three failures before achieving the successes, however, indicates that they get themselves hopelessly lost in the wilderness.
Designing Skill Challenges More so than perhaps any other kind of encounter, a skill challenge is defined by its context in an adventure. Adventurers can fight a group of five foulspawn in just about any 8th- to 10th-level adventure, but a skill challenge that requires the PCs to unmask the doppelganger in the baron’s court is directly related to the particular adventure and campaign it’s set in. Follow these steps to design skill challenges for your adventures.
Step 1: Goal and Context
What’s the goal of the challenge? Where does the challenge take place? Who is involved in this challenge? Is it a stand-alone skill challenge or a skill challenge as part of a combat encounter? Define the goal of the challenge and what obstacles the characters face to accomplish that goal. The goal has everything to do with the overall story of the adventure. Success at the challenge should be important to the adventure, but not essential. You don’t want a series of bad skill checks to bring the adventure to a grinding halt. At worst, failure at the challenge should send the characters on a long detour, thereby creating a new and interesting part of the adventure.

Give as much attention to the setting of the skill challenge as you do to the setting of the rest of the adventure. You might not need a detailed map full of interesting terrain for a skill challenge, but an interesting setting helps set the tone for the encounter. If the challenge involves any kind of interaction with nonplayer characters or monsters, detail those characters as well. In a complex social encounter, have a clear picture of the motivations, goals, and interests of the NPCs involved so you can tie them to character skill checks. A skill challenge can serve as an encounter in and of itself, or it can be combined with monsters as part of a combat encounter.
Step 2: Level and Complexity
What level is the challenge? What is the challenge’s complexity? Choose a grade of complexity, from 1 to 5 (1 being simple, 5 being complex).
Skill Challenge Complexity Complexity 1 2 3 4 5
Successes 4 6 8 10 12
Failures 2 3 4 5 6
Level and complexity determine how hard the challenge is for your characters to overcome. The skill challenge’s level determines the DC of the skill checks involved, while the grade of complexity determines how many successes the characters need to overcome the challenge, and how many failures end the challenge. The more complex a challenge, the more skill checks are required, and the greater number of successes needed to overcome it. Set the complexity based on how significant you want the challenge to be. If you expect it to carry the same weight as a combat encounter, a complexity of 5 makes sense. A challenge of that complexity takes somewhere between 12 and 18 total checks to complete, and the characters should earn as much
Is This a Challenge? It’s not a skill challenge every time you call for a skill check. When an obstacle takes only one roll to resolve, it’s not a challenge. One Diplomacy check to haggle with the mer‑ chant, one Athletics check to climb out of the pit trap, one Religion check to figure out whose sacred tome contains the parable—none of these constitutes a skill challenge.
