Advanced Ancient Academy is a classic dungeon crawl module for Old School Essentials and other old-school roleplaying games. This book includes background on the dungeon, rules for assembling the party and preparing for the adventure, a dungeon map, and details for more than 40 locations.
This module is designed for a group of 4 to 6 player characters of 1st or 2nd level. Larger groups or player characters of a higher level can also explore the dungeon but may find some encounters with monsters easier to overcome. Likewise, smaller groups may find the battles more deadly and are encouraged to be careful, quiet, and clever as they explore.
This is an expanded version of the original one-page Ancient Academy adventure.
