From publisher blurb: The first fourteen levels were only the beginning! Confound your players with a whole new level to add to your Castle of the Mad Archmage™ adventure. Level Three East describes the wonders of the Mad Archmage’s own museum, which contains curiosities and treasures from all over the multiverse, and the challenges of the Watery Caves, which are a series of living caves connected by an underground river. This module features 74 new encounter areas and 6 new monsters, a full two-page map, plus new magic items, new rumors, an explanation of how this module fits into the whole Castle structure, and the impact it will have on the inhabitants of the central third level of the dungeon. There are also tips for game masters who would like to run this level as a stand-alone adventure. Levels in the dungeon roughly comport to suitable character levels, to this module is best suited for PCs of approximately 3rd level. However, there are (intentionally) some encounters that only more powerful characters can expect to handle.
