From the publishers blurb:
Puzzle Dungeon: The Seers Sanctum is a system neutral adventure for characters of level 1 to 4.
When I first started running games, I was disappointed by the lack of cohesive puzzles in adventures that I found. The ones with puzzles usually didn’t feel like they belonged in the adventure or they weren’t of the design caliber that I was used to coming from the classic Legend of Zelda games.
I wanted dungeons where each location has its own mysteries that the players have to unravel as they can poke around and experiment with their environment and the equipment they find.
Where not everything makes sense at first, but as they come back and explore previous areas with acquired knowledge and magic items, the pieces start to come together and they’ll be able to unlock the main puzzle of the dungeon.
