Graveyard Keeper lets you get into dungeons to get additional resources and fulfill mission requirements. There, you can get boards, nails and other metal objects.
How to get to the dungeons?
You need the Active key if you want Snake to open the Dungeon. This quest is available since the very beginning of the game. You have to get to the Astrologist first and give him the skull. In order to get the skull, you need the hardspares skill first. It allows you to extract bones from graves. Yuck.
After extracting the skull, get it to the Astrologist. He's waiting in Sloth Day under Lighthouse at Sealight. If you give him the skull, you will get the Keepers key. Your next task will be to go to Snake. You will receive Instructions for Key from him. But in order to gain Snake's trust and get the instructions you must first bring him 5 points of faith. You may collect them during the mass
After getting 5 faith points (through masses) get to the Study table. Use faith there, keepers key and the Instructions for key, hence you can acquire the Active key, which you can give to Snake.
How to prepare for a fight?
Before you descend to the dungeon, prepare to fight some monsters. Remember that your character doesn't have many HP, so be careful. So, before descending, make sure you have armor, sword, and food.
Check the crates and the equipment - see whether you can get a better sword. If that's possible, do it. The sword can be created from any heavy resource, 4 simple iron parts, and 2 ropes.
If you got a new sword, make sure it's equipped. The game often puts new items into the inventory but doesn't put them into the hand slot so they're not used.
Create an armor. In Graveyard Keeper you can create two types of armor. In order to do that, you need the weapons skill.
In order to create iron armor, you need 4 skins and 6 simple iron parts. If you want steel armor, you will need 2 Wooden sticks and 5 complex iron parts.
You will also need some food for the journey. Each sword hit takes 2 energy points. This makes combat very difficult. Take some food into the dungeons in order to regenerate energy.
The table with the energy content of all meals can be found elsewhere in this guide.
Valuable info regarding Graveyard Keeper
Here we have a few rules and pieces of advice that will make combat in the dungeons easier in Graveyard Keeper. Combat isn't really difficult itself, but it's time-consuming. We tried to list some rules that should make things easier.
Dungeons have 15 levels - it's pretty easy to go through them and see what monsters are there.
Killed monsters don't respawn - once you've cleared a floor, there won't be any monsters there anymore. This allows you to go back there and collect the resources.
Resources don't spawn either - Make sure you collect all of them and hide them in crates to be able to manage them later.
Break vases - use an old sword to break old vases - you could drop a heal potion, Metal strap or Crop Seeds.
Destroy barrels - the barrels can drop crop seeds, nails or a heal potion.
Before going to a lower floor, clear the current level - doors won't open otherwise.
You're not immortal! If your HP is low, retreat and come back later unless you want to get home fast.
If you need to get home quick - die. Death doesn't bring any negative consequences - you can use it as a fast travel system.
