From publisher blurb:
Can You Solve the Mystery of Mastherik Manor?
A mysterious mansion has sprung up on the border between two kingdoms, Calximus and Drakungheist. The mansion is on the site of a dwarven mining colony that disappeared years ago in an avalanche. Two opposing magic schools sent by the kingdoms, Venefigrex and Zaubereich, have hired the PCs to track down the necromantic secrets it holds. But the mansion does not give up its secrets easily, and it will take clever PCs with an eye for detail and all their puzzle-solving skills to unravel the mystery of Mastherik Manor!
Inspired by escape rooms and amusement park rides, this adventure for 4th to 6th level characters features 200 tokens, 100 handouts, 70 battlemaps, 35 new monsters, 16 new spells, 12 new magic items, and a new arcane tradition (Biomancy).
