*THIS IS A D&D NEXT/5E PLAYTEST ADVENTURE* Imani, a Turmishan wizard and former adventurer, seeks the aid of heroes to infiltrate Dretchroyaster’s lair and recover the Diamond Staff of Chomylla—the key to powerful magic and wisdom locked away for thousands of years. In addition to his own sagely interest in the lore of lost Uvaeren, Imani recognizes the dangers of such powerful magic falling into evil hands. The dracolich has secured the staff in his lair’s cen- tral chamber, using ancient wards of protection that can be bypassed only by four artifact-idols once belong- ing to a cult of Bhaal. Each group of adventurers enters the dungeon through a different section of the dun- geon—a forgotten temple of Bhaal, a vast underground lake, a troglodyte village, or Dretchroyaster’s vaults. Dretchroyaster’s lair is no simple set of caverns and ancient ruins. It sits atop a source of great power and energy, which the dracolich and his Cult of the Dragon allies hope to use to unlock the secrets of the staff. Only by undertaking a unified assault against Dretchroyas- ter’s lair can the adventurers hope to recover the Diamond Staff and survive the dracolich’s fury. The adventurers must make their way through the lair and recover the Bhaalite idols that will help unlock the Diamond Staff, all the while dealing with the lair’s creatures and avoiding the dracolich as he pur- sues intruders. Entering the Chamber of the Diamond Staff, the heroes must overcome its magical wards and claim the staff before being slain by the dracolich and his servants.
