Multi-Layered Encounter Tables

Gnome Stew - 22 October 2018 - 5:00am

Table… layers… nothing?

Recently I was thinking my encounter tables seemed kind of dull. Taking some inspiration from this great article series from Justin Alexander, (specifically this part) I decided to add some layers to my encounter tables. This is accomplished pretty simply. By making a handful of themed tables that are rolled on simultaneously, it creates a more complicated set of results that are easy to work with and determine.

For my game I kept my standard encounter table as is, and just added another 2 layers: a table for interesting environmental features and a table for small treasures. By rolling on all three at once, I can create any combination of the three layers and make the result more interesting both because it has more interesting parts and because of interaction between the features. For example, if I roll some monsters and a small gem vein, maybe the monsters are trying to dig up the vein themselves. If I roll a water feature and a treasure maybe the treasure is corroded and lying at the bottom of the water, etc…

Here’s an example for exploring a ruined city area:

To check for an encounter, roll a d10 each of the three tables. On a 1-2 that component is present. on a 3-10 it is not. Then roll on the individual tables as needed.

Roll 2d4 Encounter 2 1d2 dust devils 3 1d6 worn skeletons with decayed weapons/armor 4 1d4 small rubble elementals (re-skinned earth elementals) 5 1d6 Treasure hunter NPCs 6 1d4 wild dogs 7 nest of 1d8 rats and 1d3 dire rats 8  giant hunting spider


Roll 2d4 Terrain feature 2 precariously balanced pile of rubble 3 Sinkhole hazard 4 Ruins with vantage point/platform 5 Water filled area (depression, fountain, basement etc…) 6 Overgrown scrub/grass may be edible variety 7 Bit of carving/plaque 8 small 5 room basement/lower level


Roll 2d4 Treasure 2 Map or note 3 piece of art or jewelry worth 10-80 gp 4 Misc interesting object* 5 3d10 lbs of bent and rusty metal salvage 6 Well preserved piece of gear 7 1d10 each loose cp, sp, gp, and pp 8 Dented lockbox with 3d4 small gems of 10-40 gp value each

So we might get any of the following encounters:

  • Nothing
  • The remains of an old garden. It is overgrown and thorny but a few bitter green melons can be harvested from it.
  • A group of 5 treasure hunters. They have recovered a misc interesting object.
  • 3 worn skeletons with ruined gear
  • etc…

A few notes:

  • Because we’re rolling for each table separately, it’s possible to have one or two of the components without the other(s) I don’t have a problem with that. If it doesn’t work for your game, feel free to change your roll method.
  • Also because we’re rolling separately, the chance of “something happens” isn’t .2 even though each table triggers on a 1-2. Instead the chance of “something happens” is 1-(chance of fail 1 * chance of fail 2 * chance of fail 3). In this case 1-(.8*.8*.8)=.488 If you don’t like that rate, change the base rates for the three tables. They also don’t all have to be the same. I used .2 each for simplicity, but you could decide that encounters have a .2 chance, features a .3 and treasures a .1 (which gives an overall chance of .496) or .2 .2 .05 (.392). Whatever works for you.
  • Hey, that’s a lot of rolling. If you like the old school approach, this is a great use for the die ten million. For me, I’ve got most of my notes in Google Docs anyway so I used Google Sheets and the randbetween, if, vlookup, and match functions to roll an entire day’s worth of encounters on every update. Easy-peasy.
  • Of course what tables you find useful and interesting are entirely up to you and depends on your game.

And a shout out:

  • You see the table above has a Misc Interesting object on it. On my tables, that’s just a link to the 100 Filched Items From Picked Pockets And Cut Purses PDF from Fishwife Games but you could just as well use the 5e DnD Trinkets table (Players Handbook page 160) or any other similar table you like. I just find it’s fun to have a big ol’ list of little interesting crap in my treasure tables.

What is an RPG? - by Caleb Compton Blogs - 22 October 2018 - 12:41am
RPGs are one of the most deceptively complex game genres out there. It's easy to spot a First-Person Shooter - you shoot things in first-person. However, RPGs are not so simple. In this article we get to the bottom of what defines this elusive genre.

Don’t Invest In Your Campaign…At First

Gnome Stew - 19 October 2018 - 5:00am

It is fair to say that I have run a number of campaigns. Some epic, some pretty good, and plenty that were meh or worse. Over time, I have gotten a good feel about if a campaign has what it takes to be worthwhile or not, but it takes a few sessions to be sure. Knowing that, I have made it a practice not to put too much detail or effort into an early campaign until I am sure that it is going somewhere.

The 50 Page Campaign

I did not always follow the advice above. There was a time when I would spend quite a bit of time working on campaign ideas, settings, plots, NPC’s, etc in order to prep for a new campaign. Some time back, at the turn of the century, I was setting up to run a Mutants & Masterminds campaign. I got really into creating this alternative history for the world, deriving all the changes in modern history and culture with the arrival of superheroes during World War II.

As settings go, it was easily one of my best ones, and it culminated with a 50-page alternative history that explained the whole setting. The campaign lasted about 4 sessions before the players lost interest. Truthfully the setting had some issues. It was plenty realistic…too realistic.

The point is that I spent way more hours working on the setting/campaign than getting to play the actual campaign. That for me was rock bottom. After that, I swore off investing too much in campaign prep.

The Campaign Prep Tightrope

There is a problem with not investing in campaign prep, and that is that the game may not be interesting enough to keep running unless you do some prep, and that by doing none you may have committed your game to failure. So you have to do some prep to make sure the game takes off, but not so much that if it fails you will regret the time spent. It’s a tightrope.

Depending on the game you play, what you need to prep for a campaign is going to differ. Some RPG’s — like many Powered by the Apocalypse games — do enough initial prep that just running the first session generates enough material to get going. Other games are not that helpful, and you wind up having to do some work to have enough to get the game started.

The Rule of Four Sessions

I have a rule about campaigns. I give them four sessions (defined as the time we sit down to play a game) before I ask my players if the game is worth continuing. Four sessions gives you a reasonable time to understand the mechanics, the setting, etc. Four sessions also gives the players enough time to figure out if their characters work, need tuning, etc.

 Here is the thing. I don’t save limping campaigns, I humanely put them down. Share1Tweet1+11Reddit1EmailHere is the thing. I don’t save limping campaigns, I humanely put them down. Either my players are positive and want to keep playing, or I take the next book off the massive stack of unplayed games I have collected via Kickstarter, and we play something else. A’s are passing in this class.

Just Enough Campaign Prep

Now we are getting somewhere. Knowing that in four sessions the fate of the game will be decided, your prep should be scaled appropriately. What does that mean? Here are a few tips:

  • Avoid deep conspiracies and plots. Those are a lot of work and need more than 4 sessions to complete. If the game takes off, you can build one of those starting in session 5.
  • Be evocative and vague. When you name and describe things, make sure that you are being evocative enough to capture the players’ attention, but at the same time be vague so that you don’t have to invest time in creating backstory. For instance: The God of Smiling Retribution.
  • Run a one-shot. Depending on how much material you can get through in four sessions, you may not need more than a one-shot (defined as a single story; start, middle, and end) to play through all your sessions. In many cases published material winds up being able to fill that time.
What If It Takes Off?

So after the fourth session, everyone is on board. Now is the time to ramp up your campaign prep, and get this campaign into full gear. Here are a few ways to make that happen:

  • Build an Arc. Plan out a multi-session story arc to be the first arc of the campaign.
  • Add depth to a few NPCs. Based on the NPCs that the players took interest in during the first four sessions, add some backstory and motivations to them.
  • Build your villains. Did the opposition in the first four sessions survive? If so, its time to get them ready for a campaign. Figure out who they work for, what other plans they have, and who works for them. If they did not survive, who is going to miss them and want revenge?
  • Retcon. If you made something in the first four sessions and your game survives, then you can retcon what that meant to the greater campaign world.
Know When To Hold ‘Em…Know When To Fold ‘Em

Starting a campaign can take some work, but don’t make it too much work for yourself until you know you have something good going on. A solid four sessions will let you know if you have a campaign or if you have been playing a slow one-shot. Make sure you prep enough to make the game interesting but no so much that you will regret if the game does not take off. Likewise, once a game takes off, dive in and build out that awesome campaign you envision.

What about you? Have you ever over-prepped on a campaign? Do you have a four-session rule? How do you know when a campaign is a hero or a zero?
