The Academy Edit
It is the Academy that teaches young Dungeonmens how to prevail against the terrors of the world. While towns provide Dungeonmens with the necessary hardware, the Academy provides you with Skills and Knowledge. You can upgrade it to make the game easier for future graduates, by returning artifacts back to the Academy.
Proof of Stremf Edit
For each PoS you return you get 3 points to spend at the Academy Battlemaster to raise your attributes. Furthermore, all future students from the academy get 1 point right from the beginning. PoS are the most common of all Artifacts. Collect them to get real beefy Dungeon Mans!
The Lab has 3 Tiers; after you reach a certain tier, all future students get the potions preidentified (provided they choose to learn it from the Lab).
The Library Edit
The library is upgraded by returning books. There is an extra dialog option at the Academy Headmaster to turn them in, since books also grant you the option to learn skills for free. If you upgrade it, the librarian will be able to teach you to identify scrolls. If you reach the final tier of the library, it will also contain 4 books for each new student. Knowledge is power, gather it fast!
The Museum Edit
The museum serves 2 purposes: Firstly, it collects your knowledge about monsters. There is a second kind of book, which increase your knowledge about enemies. If you increase your knowledge about your enemies you will see how much hit points they have left and might also find out about their strengths and weaknesses. Additionally, you can turn in Mysterious Items. Like equipment, they come in 5 tiers. This grants future graduates of the Academy a hand full of more powerful starting items. For free!
The Armory Edit
Here you can melt down equipment that you don't need and neither want to sell in towns for future students to buy back. Its use is self-explanatory. I'm lazy!
Ghost Professors Edit
Really high educated graduates return as ghost profs if they die at level 10 or higher. These guys give you a whole talent. Yes! You start these sweet level 6 skills at level 1. So teach 'em and rip 'em!
The Workstation Edit
After you found the hidden tower, monsters will start to drop map items which allow you to create new dungeons on the overworld. Those are can have special enemy sets and should have their own article.
