Vault of the Dracolich was an adventure module for the D&D Game Day in June 2013, for the 5th edition of Dungeons & Dragons.
“
Deep in the forest of Cormanthor lies the hoard of the dracolich Dretchroyaster, the prize of which is a diamond staff rumored to unlock the secrets of an ancient elven kingdom. The sage Imani is seeking dozens of adventurers to launch an all-out assault on the undead dragon's lair. The dracolich is a powerful foe - too great for even several parties to conquer - so it's going to take all of the heroes' courage, cunning, and speed to survive the dracolich's deadly vault.
Vault of the Dracolich is a Dungeons & Dragons Roleplaying Game adventure designed for the June 2013 D&D Game Day. The challenge draws inspiration from the interactive format used at some gaming conventions.
