In the old days, you couldn’t get a pre-made module that didn’t have at least one random encounter chart, usually several. In 4th edition, the trend seems to be heading the opposite direction.
I think that a solid understanding of what a random encounter does will help you decide how to include them into your game, if at all.
First the Cons
- They generally serve no purpose for the story.
- They cause fluctuations in XP and treasure. Usually the party gets XP but no treasure. Too much of this sort of thing makes for game imbalances.
- They cause Party Wipe. All too often the random nature of the encounter produces something too powerful at the wrong time.
- They use up party resources which can lead to either Party Wipe, character death, or game imbalances because the party’s single use resources (potions & scrolls) are used up before their time.
- If used in conjunction with random treasures, you can (and often do) get too much treasure or totally useless treasure.
Then the Pros
- You don’t have to plan ahead for them, so it can save you time.
- They fill session time when the party decides to go somewhere you hadn’t planned on.
- They can be used to boost XP if the party has more treasure than their level suggests they need.
- They can be used to kill off annoying characters.
- They can be used to boost treasure if the party doesn’t have enough.
In general I never use truly random encounters. I ignore the tables. However I do use pseudo-random encounters all the time. I make up a few extra encounters when planning for a session. These are always the same level as the dungeon encounters I expect (or hope) the PC’s will find, and either have equivalent treasure or no treasure.
Here are the situations I use them for.
- The PC’s are heading to the dungeon and will eventually get to the dungeon, but not this session, and they need a combat to get them moving. In this case I will remove the first dungeon encounter from the campaign. If there was a treasure with that encounter I will usually leave it in the dungeon to be found next session (though there is nothing to stop you from handing it out now).
- The PC’s will never reach the dungeon and the dungeon encounters I have prepared simply make no sense whatsoever where they are now. For example, the only dungeon encounter I have left is a gelatinous cube and they are in a forest. See more on encounter swapping here.
- Somebody pissed me off and I’m in a vindictive mood. So I hit them with an extra encounter while they are trying to rest and gang up on the jerk who took a bite out of my chocolate cupcake.

Hope these ideas help, and as always have fun!
