Hadrim's Maze

From publisher blurb: 5th Edition Mini-Dungeon for five characters of levels 5-6 Hadrim is an accomplished wizard with an embarrassing problem. He has a reputation for training the greatest magic users and the tests he develops for his students enjoy almost the same renown as his incredible exploits. The most famous test is Hadrim’s Maze, through which apprentices must navigate to three shrines to procure three gifts before exiting. The task sounds simple, but few pass on their first attempt. Recently, Hadrim foolishly agreed to allow one of his less promising apprentices to enter the maze, with disastrous consequences, as a summoning spell went haywire and infested the maze with “multicolored flying slugs.” The creatures compromised the magic of the maze, forcing Hadrim to save his apprentice with teleportation magic, which caused further damage. Now Hadrim needs professional help to clean up the mess.
