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.
