Fixing the Encounter Tables Part II

How tough should random encounters be?

In order to set encounters that pose the correct challenge, I've created a very average 1^st level party and worked out their Monstermarks.

1^st Level Fighter 2.00

1^st Level Fighter 2.00

1^st Level Dwarf 2.00

1^st Level Cleric 1.20

1^st level Thief 0.65

1^st Level Magic-User 0.40

Total Party Monstermark value 8.25 (we'll round it down to 8.00)

For this party, I think random encounters with a mean value of around 4.00, and a maximum value of around 12.00 (in effect the mean is -50% of the party's power and the maximum is +50%) are ideal. There's a degree of flexibility in these ranges. Indeed, for some creatures with a very low Monstermark, the existing number encountered ranges in the monster listings may be used without modification. For example, a Kobold has a Monstermark of 0.47. The Labyrinth Lord rules give the number encountered as 4d4 giving the encounter a mean Monstermark of 4.70 and a maximum of 7.52.

Here's some examples of popular monsters and my proposed number encountered ranges:

Kobold (MM 0.47) 4-16

Goblin (MM 0.99) 2-8

Skeleton (MM 1.17) 2-7

Orc (MM 1.27) 1-6

Hobgoblin (MM 2.51) 1-4

Zombie (MM 3.48) 1-4

Gnoll (MM 5.00) 1-2

Bugbear (MM 11.27) 1

Any one of these encounters has a chance of killing an unlucky party, but experienced players might handle several of them in succession regardless of luck. Although there is the potential for encounters that outnumber and/or overpower the party on paper, the party have lots of tools and options open to them including:

• Tactics (eg: fighting in doorways, running away, etc.)
• A Sleep spell
• A Cure Light Wounds spell
• Thief skills
• Dwarf abilities
• Turning Undead
• Talking

Fixing the Encounter Tables Part I

Yesterday, I listed the various first level encounter tables that I'm using to generate my own Monstermark driven version.

Today, I've gone through the Labyrinth Lord rules (including the AEC), and made a list of all the monsters with a monstermark low enough for the level one table.  I may have missed a couple of monsters out, but this is still work in progress and when I've finished tables for the first few levels, I'll decide what needs to be moved up and down.  In Oubliette 6, I plan to include the master tables in the magazine, with some additional tables in the supplemental materials section which can be quickly editied to add/remove creatures, and adjust the % chance of encountering them.

Next, I'll spend some time calculating Monstermarks for creatures in the list that I haven't already worked out.  Then I can begin deciding what number encountered ranges to use, based on an average total Monstermark and the average number of saving throws a party might be required to make.

Broken Encounter Tables

Today I've been working on my revised set of random encounter tables for Labyrinth Lord, ready for publication in Oubliette 6 next month. I'm using the Monstermark rules in the previous issue to try and make them a little more balanced. In researching the article, I've looked at various encounter tables from D&D books and modules, the AD&D DM's Guide and the ones in Labyrinth Lord itself.

Looking at them, what struck me was how varied the threat offered by some of the encounters are. Interestingly, some of the least deadly are the ones in the DM's Guide,which surprised me given the fact that AD&D characters will on average be tougher than basic D&D ones.

Out of all the first level encounters, the most deadly one - and I'm speaking from experience here* - is 1d4 of Giant Crab Spiders. Not only do these nasty beasts have a decent amount of Hit Points (2HD), they also surprise opponents on 1-4 on a d6. This means that if a first level party encounters 4 of them and are unlucky with surprise and initiative rolls, the spiders could get 8 poisonous bite attacks in before the characters make a move. After that, the spiders should easily survive a few more rounds. Unless the party magic-user has still got a sleep spell you've probably got a TPK situation.

*We met 4 of them on the first level of Stonehell. They killed my cleric - still bitter about it.
