About this Mod

Cobblemon Special Fossils

Adds additional variants for a bunch of Cobblemon fossils. They can be guaranteed shiny, have full max IVs, or have their hidden ability, as well as combinations of those.

You'll be able to tell from the inventory icon of the respective fossil which of those properties, if any, it has. For the Galarian fossilmon, both parts will need to have the same properties.

Support for several popular mods is also being worked on, where feasible.

Since the new variants are distinct items, they can easily be added to loot tables or spawned in by mods. By default, they'll be added as archeology loot to the same pools that the base fossils belong to.

Supported Fossils

  • Cobblemon (all fossil items and fossil Pokémon)
  • Complete Galar Fossilmon (all fossil Pokémon)

Configuration and Rarity

There is a configuration file that is automatically generated on first load. This contains two settings: baseDropChance, which scales the overall rarity of dropping a variant fossil rather than a vanilla one (range 0.0-1.0, with 1.0 meaning one third of fossils will be variants), and variantRatio, which holds a three-way ratio for the relative rarity of different variants in the form of an array of three integers. These will be interpreted as "a:b:c", controlling the relative rarity of variants with one, two, and three of the special properties respectively.

The above values are used both for the archelogy loot tables from Cobblemon itself and for the Cobbleworkers integration.

Accessibility

The special properties are signaled by up to three "sparks" on the item itself, which are consistent in both color and position. For those with color blindness or other vision problems, they are also included in the tooltip of the item.

Dependencies

  • Cobblemon >= 1.7.3
  • Fabric API 0.116.8+1.21.1
  • (Optional) Cobbleworkers - if installed, the new fossils variants will occasionally be dug up by the "archeologist" job
  • (Optional) Complete Galar Fossilmon
  • (Optional) Cobblemon Chimeric Shinies - if installed, combining Galarian fossils that only differ in shininess will result in chimeric shinies
