Lair of the Medusa: A Random Level 4 Dungeon Part 1

It's fun to roll a B/X dungeon! It really gets the creative energy flowing. One doesn't even need a map!

This 25-room level 4 dungeon was stocked by rolling on the table in the Basic Set, p. 52. The monsters were rolled using a 20-sided dice on the table in Rules Cyclopedia, p. 94. (I rolled a 12 three times, resulting a lot of Medusa!)

However, the treasure will not be rolled randomly. Instead, the dungeon will be designed to raise six, level-4 characters to level 5 once cleared. Cash and magic items will be designed and placed accordingly.

As for placing cash treasure; six PCs going from level 4 to level 5 require 8,000 xp each or 48,000 xp total. If we want them to level in three sessions (knowing it will likely take five), that would require 16,000 xp per session, or about 2,700 xp per session individually. Players are unlikely to find it all, and some PCs need more xp to level than others, so we'll add a little.

The above process, including typing, took 45 minutes (10:30 p.m. to 11:15 p.m.)

To be continued!

Next time, I'll write a sentence describing the dungeon and one sentence describing each room, trap, treasure, and encounter.

 

A trap and treasure in the first room. Ooo, I wonder what it is!

Multiple Medusae in the early rooms, then a Hell Hound guarding a treasure vault. Wonder what's in there . . . 

A Medusa, two trolls, and four harpies are all together in the same region, it would seem. That dynamic should prove interesting to detail. 

In a different area, a rust monster, two gargoyles, and two werewolves all nearby; another interesting combination.

At the exit—or alternate entrance—we have another trap and treasure. Hmm . . . I wonder if it could be similar to Room 1 . . . Maybe to gain entrance, you have to leave the treasure alone? Or, maybe you have to take the treasure, springing the trap, and revealing the entrance . . . 

Tune in next episode!
