About this Mod

Warning: Generally recommended you use the data pack version if you plan on downloading other mods/data packs that mess with Cobblemon's species files or species additions. Mod version's mainly here for exposure!

We're a pack dedicated to remixing hundreds of existing moves, abilities, items, Pokemon, and even some battle mechanics within the Showdown portion of Cobblemon to further help fit the open-world nature of Cobblemon and let you go full ride or die with your favorites in new and exciting ways!
OVER 1100 EDITED FILES!

Full documentation of the hundreds of things changed is here!

NOTICE: This is the preview version of Project Lazuli. Although you can install this on an existing instance, just keep in mind that this among many other changes, also changes learnsets, abilities, and the like, adding and removing some here and there.

FIRST-TIME INSTALLATION INSTRUCTIONS FOR DATA PACK VERSION (Mega Showdown required) Download these recommended mods.
  1. Just download, and put it into your data pack loading and resource loading mods of choice!
  2. That being said, you should enable cheats for now, unless you're confident you know what you're doing.
TECHNICAL STUFF, WARNINGS & KNOWN BUGS

Project Lazuli is a combination of a data pack and a resource pack backed by the power of Mega Showdown's extra loading capabilities for editing custom type charts, conditions... everything basically that isn't custom moves/abilities. However, there are a few things Mega Showdown alone can't do, so keep this in mind:

  • This pack does the forbidden sin of directly editing certain Pokemon's species files. This is because (at the time of writing anyway) species_additions cannot target the alternate forms of Pokemon.
  • In the same vein, for some reason or another, our data pack needs to be loaded pretty much after ALL OTHER Cobblemon-related datapacks, even with species_additions. This is due to how Cobblemon currently loads additions. However, the download you'll recieve is tailored to help make sure it's loaded last.
  • This means that if you're installing any other data packs that tweak existing Pokemon, check and make sure they don't do the same thing. If they do, you may need to manually merge our changes with their changes as you see fit.
KNOWN INCOMPATIBLE PACKS/MODS

Gravel's Extended Battles

The reason why this is currently incompatible though is because it directly changes the Showdown cache in its own way, not using Mega Showdown's cache changing data packs. We'll keep this updated as time goes on.

Rize Tweaks

For some reason or another, combined with this pack, the PC won't open. Might or might not work as of this update?

Cobblemon UI Tweaks

Very minor incompatibility: Its move tooltips don't update for Project Lazuli moves.

If need be, we have a support channel on Cobblemon's Discord Server, or coming soon on Mega Showdown's Discord server.
