Library

Unlock Keeper's secrets! Learn about the Library's function, research costs, Warlock behavior, and the fixed order of spell and room unlocks.

Alright, let's talk about the Library in Keeper. This is where the magic happens, literally! It's where your creatures can get to work researching new spells for you, or even unlock those advanced rooms you'll want to build later on.

Cost & Research: Building a Library tile will set you back 200 gold. Each tile has a research value of 1000. Now, the guide says researching the Library itself is usually a waste of time, so don't worry about that. The real value is what it unlocks.

Warlock Woes: Warlocks are automatically drawn to research. Here's a crucial tip: if you have Warlocks above level 1, they'll get aggressive towards any creature that isn't a Wizard or Warlock wandering into the Library. So, either hold off on training your Warlocks too early, or make sure you build your Library in a more secluded spot, away from your other dungeon dwellers. Nobody wants a Warlock brawl disrupting research!

Research Points & Unlocks: Every room or spell has a specific 'Research value'. Once you hit that target number of research points, the spell or room becomes available. The more advanced the item, the more points you'll need. That 'Destroy Walls' spell? It's a whopping 750,000 points, so get ready for a long wait if you're aiming for that one!

The Unlocking Order: It's important to know that the order in which spells and rooms are researched is fixed. Even if some take way longer than others, they unlock in this specific sequence:

1. Create Imp (usually available)
2. Treasure Room (usually available)
3. Lair (usually available)
4. Hatchery (usually available)
5. Training Room (usually available)
