Campaign Planning

Planning out a campaign is difficult for a variety of reasons. Mapping the ebbs and flows of the story, plotting the course for antagonists, and laying plot hooks can all take a great deal of planning and forethought.

This article will help you with none of those problems. Instead, this article breaks down the underlying math and mechanics of a campaign run from 1st level through 20th, including all of the encounters, experience, and treasure. By making some base assumptions we can build the mechanical skeleton of a campaign and determine exactly where things need to go.

But why do this? Why is this important? Because I have never once met a DM who thought of an entire campaign starting at the beginning and proceeding in order to the end. That's now how people think. If you've ever had a great idea for a dungeon or a piece of treasure and didn't know where to fit it into your campaign, this article will help you do it. If you've ever worried that you don't have enough content to get players to level 20 (which isn't necessarily a bad thing), this article will help you find out where you have gaps. If you've ever worried that you're not giving your players enough treasure, this article will help you determine exactly where and when you should place it.

This article clearly answers several questions about 5th edition and its underlying math:

Assumptions

The remainder of this article relies on a handful of assumptions. Tweaking these assumptions will result in changes to the "skeleton" which we will be building in this article.

Experience Points

The campaign skeleton will assume that you are awarding experience points rather than using "Milestone Leveling" or some other system. This means that players will need a certain number of encounters of CR equal to their level worth of experience to gain a level.

This is one of the easier assumptions to change. You can use the campaign skeleton to get an idea of the number of encounters to include, then abandon experience points altogether, thereby achieving more flexibility in encounter design without altering the pace of the game.

Default Random Treasure

The Dungeon Master's Guide includes rules for random treasure. These rules don't account for games with varying levels of magic, and they assume that you are using magic items in your game. We will make the same assumption because the majority of Dungeons and Dragons campaigns include magic items.

If you don't want to use magic items in your game, remove them. 5th edition is balanced to be played without magic items, so this shouldn't have any further effect on the campaign skeleton.

4-Player Party

The math for CR assumes that a single creature is an average-difficulty encounter for four player characters. Therefore, the rules for treasure assume that the treasure is divided among four characters. I'll attempt to break this down into individual treasure to allow the campaign skeleton to scale up and down for parties of different sizes, but some amount of rounding will be required.

The Adventuring Day and Short Rests

Page 84 of the Dungeon Master's Guide describes "The Adventuring Day". This establishes a rough guideline for how many encounters players can handle in any given day, and suggests roughly two short rests per day. These assumptions give us a guideline for how much adventuring you can squeeze into a single day, which in turn tells us how quickly you could expect to run players from level 1 to level 20 if you were to do nothing but adventure as quickly as possible.

Gaining a Level Requires a Long Rest

While there is no rules guidance on the subject, I'm going to assume that you require players to complete a short rest before gaining a level. Gaining a level without taking a long rest introduces a lot of very complicated math that I don't find interesting or meaningful.

A big pile of math

If you want to just trust me and ignore all of this interesting and useful math, skip to The Skeleton, I won't think any less of you, But if you want to understand the math and logic behind how I built the skeleton, settle in for some math, statistics, and tables full of numbers.

How many encounters per level?

The table below includes the math to determine how many encounters of average CR will bring a player to the next level. Based on our assumptions discussed above, this assumes a party of four characters facing encounters made solely on single monsters of CR equal to the players' level. This math largely disregards experience from other sources, but it tells us enough that we can build the skeleton.

The table reveals some really interesting information:

Encounters per character level
Level / CR CR Exp. Exp. per Player Exp. for next Level Exp. to next Level Encounters to next Level (Raw) Daily Exp. Budget Encounters Per Day Days to Level

Total Encounters: 198.19 Days to Level 20: 30.3
Treasure

The final paragraph on page 133 of the Dungeon Masters Guide sets an expected number of rolls on the Treasure Hoard tables, but does not specify how much treasure to award from the "Individual Treasure" tables, so the table below attempts to fill in the missing information. We'll assume that each treasure horde replaces the treasure for one encounter, and the remaining encounters will use the individual treasure tables.

Unfortunately, because the number of encounters per level is almost never a round number, neither is the number of rolls on the treasure table. Fortunately we don't actually need round numbers because this is all an exercise in math and probabilities which will end with a pile of coins of various denominations.

Individual Treasure rolls per tier

0-4 35.48 7 28.48 3.52 gp 100.28 gp

Total GP gained over 20 levels: 191,521.34 gp

Treasure Hoard Distribution

We've now established how many times the DM will need to go roll on the random treasure tables in each tier, but that leaves us with large ranges over which to distribute treasure hordes and no official guidance on how to do so. I've got several ideas for how this could be done, so we'll go through them in what I think is worst-to-best order. I'll include a table and graph at the end to clearly lay out horde distribution so that we can compare them easily.

Big Pile

Award all treasure hordes in the final level of the tier.

This is an outright terrible idea. Players will go through huge stretches with no treasure greater than the change rattling around in enemy pockets, and won't get new magic items for long periods until suddenly they find a pile of them in some dungeon or something and experience a sudden and confusing leap in power.

Flat Distribution

Distribute the hoards evenly over the level tier.

This is a perfectly fine way to do things, but it has some warts. Entering a new tier comes with a sudden and significant jump in the value and power of treasure which players find. Toward the end of the tier treasure feels lackluster because players are getting the same quantity of treasure that they recieved several levels prior.

Ramp

Distributes hoards such that each level has more hoards than the previous level.

The Skeleton

With the above information in mind, we can finally build our campaign skeleton. Think of this skeleton as a long list of blanks which need to be filled with encounters and rewards. We'll use the "ramp" method for distributing treasure hordes, but feel free to replace this with other methods if you'd like.

In addition to the option of randomly generated treasure hordes, I've included column for manually specified treasure. The logic for this column is taken from this ENWorld forum post which goes into the statistical distribution of magic items over a character's career from levels 1 to 20. The treasure horde rules don't scale well for parties of more/less than 4 players, but the analysis in the forum post makes it very easy to scale the number of magic items in your campaign to accomidate parties of differing size.

  • Standard Encounters: Conventional encounters with monsters which don't typically collect large treasure hordes.
  • Individual Treasures: Treasure from standard encounters. Generated by rolling on the Individual Treasure tables on page 136 of the Dungeon Master's Guide.
  • Hoard Encounters: Encounters with monsters that like to collect treasure, such as dragons, beholders, or major NPCs.
  • Treasure Hordes: Treasure from Hoard Encounters. Generated by rolling on the Hoard Treasure tables starting on page 137 of the Dungeon Master's Guide.
  • Precise Magic Items: Instead of using the Treasure Horde tables, you can use this column to plan specific magic items to grant throughout the campaign. The column represents magic items for each player, so you must multiply the number of items in the column by your number of players. You may wish to redistribute the position of permanent magic items to avoid giving out magic items all at once.

That's a very strangely shaped skeleton.

Planning Encounters

Humor aside, we now have our campaign skeleton. Now we know exactly how much content we need to put in front of the players to get them to 20th level. But we still have one lingering question: What do we do about the non-round numbers? A DM can't actually make 0.65 encounters.

Remember that not every encounter needs to be a single monster of CR equal to the party's level. Use encounters of varying difficulty; their experience point values will vary accordingly, and by adjusting the difficulties of a few encounters up and down you can easily hit nearly any number. I recommend making roughly 25% of encounters easier than normal, 25% harder than normal, and 50% average difficulty. By adjusting the total experience value of encounters and adding in experience for traps, puzzles, and story rewards You can easily compensate for non-round numbers of encounters.

Example - Planning a Level

Planning out any single level is roughly the same. To illustrate the process, we'll plan out content for taking a party of four characters from 4th level to 5th level.

The Skeleton specifies that it will take 13.87 encounters (10 regular and 3 hoard encounters) to take players from 4th level to 5th level, and the daily experience budget for 4th level gives us room for 6.18 encounters per day. That means that players will need to face 2.24 days worth of experience to reach 5th level.

We can address that in two ways: we could spread the encounters over three adventuring days, stretching our experience budget a little bit thin and making each individual day a bit more manageable for the players; or we could do two days worth of adventuring and award some story experience rewards for things other than fighting monsters like traps, puzzles, and story rewards.

In this example we'll go for the second method. We'll assume that each adventuring day includes a handful of traps, a puzzle, and a small story reward at the end of the day.

I like to make roughly 25% of encounters below average difficulty, and roughly 25% of encounters above average difficulty. 6 doesn't divide into neat quarters, but we'll have 1-2 easy encounters per adventuring day and 1-2 hard encounters per adventuring day. Easy encounters should generally be grouped with hard encounters in order to stay within the daily experience budget so that players' daily resources aren't overtaxed to the point that they don't have a reasonable chance of success.

We also have three hoard treasures to award, and I've always liked awarding more treasure for harder encounters, so I think we'll award treasure hordes for our hard encounters where it's possible to do so.

Level 4 Campaign Sub-Skeleton
Encounters XP Threshold Day 1 Day 2
Easy 500 1 2
Medium 1000 4 2
Hard 1500 1 1
Deadly 2000 0 1
Free XP - 800+ 300+
Individual Treasure - 5 4
Treasure Hoards - 5* 2
* - Because we've deviated from the assumption of 1 monster of CR To keep to the expected treasure, we'll add an additional individual treasure. This could awarded from a trap, rolled into a treasure hoard, or awarded at some other point in the adventure.

That gives us a rough idea how we'll lay out our two days of adventuring at 4th level. How we join the two days doesn't matter all that much. They could be party of a multi-day adventure like a long dungeon delve, or they could be two totally separate adventures. It doesn't really matter for our purposes because this is just an example and I'm not actually running an adventure.

From here, all you need to do is create the encounters, roll the treasure, and drop them into your game. I won't go into the details of planning each encounter: encounter design is worthy of its own article.
