How to Design an Encounter

Here is how to design Pathfinder encounters! Just keep in mind that CR is a good estimate, but may change according to party makeup.

How to Calculate the Challenge Rating for an Encounter

1. Calculate the Average Party Level, or APL. That is, total the levels of each player character in the plot, then divide the end result by the number of players, and round it to the nearest number (not necessarily down). Then, add 2 because you're playing on Tenebrae. From here:

Decrease the APL by 1:

If the number of players is 3 or fewer

If circumstances are heavily slated against the player characters

Increase the APL by 1:

If there are 5 or more players

If circumstances play heavily in their favor

For example, a group of 4 consisting of: 4, 3, 4, and 4 levels would equal an APL of around 6 on Tenebrae (average is around 4th, then +2). If there was a 5th character, the APL would be at least 7.

2. Determine the challenge you want to present. Tenebrae characters are stronger than average because of their higher point buy. The following chart has been adjusted to reflect that.

Normal Pathfinder Difficulty Challenge Rating Equals Easy APL -1 Average APL+0 Challenging APL +1 Hard APL +2 Epic APL +3 Difficulty Challenge Rating Equals Easy APL -1 Average APL+0 Challenging APL +1 Hard APL +2 Epic APL +3 |} 3. Compare this modified APL with the charts, below, to determine your XP Budget. For example, if your modified APL was 6, then you have an "XP Budget" of 2,400. Multiple creatures equal a higher CR. CR Total XP CR Total XP 1-3 4-5 10 9600 1/8 50 11 12800 1/6 65 12 19200 1/4 100 13 25600 1/3 135 14 38400 1/2 200 15 51200 1 400 16 76800 2 600 17 102400 3 800 18 153600 4 1200 19 204800 5 1600 20 307200 6 2400 21 409600 7 3200 22 614400 8 4800 23 819200 9 6400 24 1228800 25 1638400 Number of Creatures Equal to... 1 Creature CR 2 Creatures CR +2 3 Creatures CR +3 4 Creatures CR +4 6 Creatures CR +5 8 Creatures CR +6 12 Creatures CR +7 16 Creatures CR +8 4. Go monster hunting. To find out how many and which monsters you can use, total the individual XP values of each monster. Then, compare the end result with your "XP Budget" number. Once you're close to your number, you've "filled" the monsters for that encounter. Don't worry if the value isn't exactly equal--just approximate it the best you can.

Tools for GMs Question Answer How can I design an encounter? We wrote an article on it! See How to Design an Encounter for your answers. Are there tools to make running encounters easier? A lot of plot runners on Tenebrae use a software called Combat Manager to help track enemy HP totals and have enemy stat blocks available at a glance. The Player-Contributed Encounter Grab Bag has some player-contributed inspiration for running your own encounters, too. Where can I find monsters for encounters? Check out the Tenebrae Bestiary. The only approved sources for monsters are listed on this page! Keep in mind that there are creature restrictions depending on what type of PRP you're running! (See Standard PRPs and Death Consent PRPs for more on those.) Dragons and demiliches are reserved for staff-only events to keep them unique. Catfolk, driders, and drow are not in theme and therefore are not permitted. What if I want to offer legwork? What IS legwork? The Legwork Mini-Guide for GMs explains it all! +help legwork in-game is helpful too. MUX versus Tabletop Encounters in a MUX tend to take longer due to the nature of the medium. This is one of the reasons we have the 2 encounter limit in PrPs.
