The Wizardarium of Calabraxis (d20)
elected as the #1 must have module by respected DCC adventure writer Daniel Bishop! Read his review.
"I hope Claytonian releases a print version in the future¸ because I need this framed on my wall with a caption that says THE BEST THIRD PARTY DCC RPG ADVENTURE." --Vorpal Mace's review
17 pages of fun¸ built around a core of an easy to run 2 page overview.
The Wizardarium of Calabraxis starts off with strangel y behaving apemen¸ but players who start to explore the cave where they reside will soon discover there is a lot going on: ancient civilizations¸ the mad experiments of a forgotten wizard¸ and a couple unique magic items are guaranteed to provide a lot of bang for your buck to your players. This module has stats for the DCCRPG¸ but if one wants to work around the weird dice¸ this module is probably at home in just about any OSR rules system.
Characters of almost any DCC level will probably have fun in this adventure; just adjust some numbers until the exact right number of PCs are dying ;)
