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.
Compatibility:
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.
Installation:-
[]Install the latest version of SMAPI.
[]Unzip the Custom Crystalarium Mod into /Stardew Valley/Mods.
[]Unzip the MailFrameworkMod into /Stardew Valley/Mods.
[]Run the game using SMAPI.
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.
