Publisher's blurb: Return to Twin Falls is a follow-up adventure from the initial adventure found in the Essential Phandalin 001 module. The PCs travel back to the ruined hamlet now that the dammed lake has been drained and must deal with the remaining bullywugs and undead inside the caves found behind the waterfalls looking for a book thought to be connected with the Spellforge in Wave Echo Mines. The adventure is designed for PCs level 4-5 and provides a map to the caves along with the monster statistics needed to play the adventure. The module is presented in an easy to read and easy to print format.
