About this mod

Adds a way to customize the crystalarium machine. It comes configurable with the Prismatic Shard but can be changed to add any 'Object' and change the time of the gems and minerals.

Permissions and credits
  • German
Current version: 1.4.2
  • New property to enable to crystalarium or cloner to clone every object.
  • New property to set the deafult time to clone for undefined objects.
  • Fix to situations where you could get a cloner or a crystalarium to duplicate items with no wait time by removing it from the ground.
  • Hungarian translation. (Thanks martin66789)
  • Change to use MFM through the interface. The dependency is not required anymore.
  • Fix logging error in game loop on some rare occasions.
  • Fix default time not working when restarting the cloner.

The first objective of this mod was to add the prismatic shard to the crystalarium as some players wished for. To make it balanced, the shard takes 14 days to be cloned. It makes the prismatic shard slightly worst than the diamond to make money with the crystalarium, so the advantage is a way to get most loved gift consistently. But will take 14 days to get the gem back, and a full month to get a second one.
Since I was already modding that, is seemed useful and easy to let players choose which ever object they want to place in the crystalarium for cloning. You can even change the current time it takes to clone the gems and minerals.
Now it can also turn other objects into cloners.

The mod might conflict with other mods that change how the crystalarium works. It's now compatible with Prismatic Tools. No other problems reported so far.

How does it work:
  • After finding your first prismatic shard, you will receive a letter explaining the changes, saying that they were wrong about the effects of the EMF interacting negatively with the shard. Since we have a book in the library giving a reason for the prismatic shard not to work, I thought it was needed to rectify the game lore.
  • The letter is just for flavor though, once you install the mod it should already be working, you can even disable the letter in the config file.
  • Once you start the game for the first time, the file 'CrystalariumData.json' will be created in the 'data' folder of the mod.
  • Here is an example on how to add more items in the file. This adds the iridium bar with 7 days  time to clone, and all trash items will be cloned in 30 minutes:
  • {
      "74": 20160,
      "337": 10080,
      "-20": 30,
      "Dinosaur Egg" : 120

  • The format of the file is an serialization of a C# Dictionary.
  • You need to place an object Id, Category or Name between double quotation marks, followed by colon and the time on in game minutes to clone the object. If you want another object, you need to place a comma and repeat. Everything needs to be between braces.
  • A full in game day is 1440 minutes.
  • You can find the item ids and categories in this page:
  • There are two config options to change the default way the crystalarium works, these are the options:
    •  Default: The crystalarium destroy the object to copy it. 
    •  BackOnChange: The crystalarium hold the object to copy it.
    •  BackImmediately: The cystalarium scan the object to copy it.

Config options:
Run the game at least one with the mod installed to create the config.json file. You can edit this file to change the configuration.
  • "DisableLetter": (false|true) Enable or disable the letter explaining about the change to the crystalarium.
  • "EnableCrystalariumCloneEveryObject": (false|true) Enable or disable the crystalarium accepting every object.
  • "DefaultCloningTime": (5000|any_number) Time in game minutes to clone an undefined object, when EnableCrystalariumCloneEveryObject is true.
  • "BlockChange": (false|true) If true, you won't be able to change the object inside. You will need to remove the crystalarium from the ground.
  • "GetObjectBackOnChange": (false|true) If true, you will get any item you place back from the cystalarium if you place a new item or remove if from the ground.
  • "GetObjectBackImmediately": (false|true) If true, the crystalarium will let you get the item you placed back immediately. Also, the GetObjectBackOnChange option will be ignored.
  • "OverrideContentPackGetObjectProperties": (false|true) If true, the "GetObjectBack" properties of the cloners will be overridem by the ones in this config file.
