DM's lives are busy. They've gotta get everything prepped for each session. Pre-made adventures can certainly help. And The Dark Pits of Krurg is just such a help. It's an adventure for characters Level 1-5 in D&D and comes complete with detailed maps of said pits. The adventure is up on Kickstarter now.
From the campaign:
In this campaign, we provide you with a collection of 5 dungeons. Each of them is designed for a specific level, from level 1 to 5. The design of these dungeons is such that both experienced DnD players can enjoy and novice players can easily interact with them.
We are going to design combat, roleplaying, and exploration encounters for each dungeon. Players encounter different characters and fascinating puzzles and riddles in rooms. There are also several traps in the players' path that make their exploration more exciting.
The campaign's up and running now with 22 days left to go.
