Versions
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!
New battling strategies await you in Project Lazuli for Cobblemon! 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.- Cobblemon Move Inspector
- Simple Resource Loader (if on Fabric) (or any other global resource AND data pack loading mod)
- Your choice of Cobblemon mod that gives you access to moves via TMs, Tutors, and Egg moves. There's several of 'em so pick your favorite.
- Mega Showdown
- AlltheMons x Mega Showdown if you want to
- Just download, and put it into your data pack loading and resource loading mods of choice!
- 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_additionscannot 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
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.
For some reason or another, combined with this pack, the PC won't open. Might or might not work as of this update?
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.

NOTE: WHEN UPDATING, IF YOU’RE USING THE DATA PACK VERSION, YOU WILL WANT TO DELETE THE OLD VERSION THEN INSTALL THIS NEW VERSION!
This is because the locations of some files have been changed, writing into your current folder is a bad idea.
This change should hopefully help some more things become compatible.

[Grab the other half here if you plan on using ZAMegas, though it isn't required!](https://modrinth.com/datapack/project-lazuli-zamegas-compat-patch)
Bug fixes: Glalie can actually learn Return, Frustration and Double Edge as TMs now. Pikachu's fixed for Mega Showdown. Yanmega can learn Nasty Plot as a TM. (The suggestion to tweak Yanmega further is still being considered for the next update, this is just the one we promised first)
As of this update, all further changelogs will be put in this handy Google doc right here. Because Discord has character limits and Modrinth seems to glitch out a bit with big changelogs. Note that I just mean changelogs, the actual changes sheet is still active!

[11] New tricks, new sets, new updates!
by shadowboxed on Dec 30, 2025
Download
New tricks, new sets, new updates! You suggested and we listened!
Pokemon Changes:
>Jellicent now has Misty Surge as a hidden ability over Damp
Jellicent is a Pokemon that actively hunts ships while underwater. It's a big, slow ghost that, much like the scariest ghosts should have, just has an eerie Mist surrounding it... so, why not Misty Terrain itself? With this, it can play some great support or even run some good setup, also bringing a sort-of Dragon resist to the table. Just be careful if you equip Heavy-Duty Boots on it, it won't be able to benefit from it!
Frillish also has Wonder Skin to replace its Damp.
>Deoxys (all forms) have Liquid Ooze as a hidden ability
Probably shouldn't be trying to sap the lifeforce of a living parasite alien, huh?
>Kyurem now has Refrigerate as a regular ability, with Weak Armor as a hidden ability. Pressure is entirely gone from it.
Weak Armor generally references how it's a husk, it's not whole at all. But, it also gives it the potential for more speed with its bulk.
>Mr. Mime now has Psychic Surge as a hidden ability (instead of Misty Terrain)
This replaces Misty Surge as a hidden ability, and helps it fit with blocking attacks! Remember that one Mr. Mime puzzle from Legends Arceus? It's a bit like that.
>Empoleon's got a new rework!
Empoleon's dex entries are always talking about how it cuts through everything that hurts its pride with its flippers, getting up close and personal to do it. With Game Freak constantly even expanding its physical movepool with moves like Wave Crash, Triple Axel and Earthquake, we figured it should get the Gourgeist treatment!
Empoleon is now a bulky, strong physical attacker with LOTS of utility. Whether you're hitting hard with Wave Crash and using Roost to heal it off after, or even spreading the new Freezing status with Frost Breath and pivoting out with a stronger Flip Turn, we hope you'll enjoy this new spin on a Pokemon we've honestly neglected for a while!
>NEW MOVES (in this update): Iron Head, Frost Breath, Drill Run
>NEW (old?) HIDDEN ABILITY: Defiant
>NEW STAT SPREAD: 84/113/93/76/106/62
Pre-evolutions are also adjusted to help match this smoothly in PvE.
>Big Pecks rework!
Instead of gaining the added ability to boost "pecking" moves, it now entirely ignores any Attack stat boosts from the opponent. It's a bit like Unaware except exclusively for opposing attack stats. This helps it sync better with its original effect of its Defense stat being unable to be lowered, while allowing more options to stop some set-up sweepers. This also helps it work better with its original Japanese name of... checks notes, Pidgeon Breast.
So similarly, those who benefitted from Big Pecks whether in the past or now got a second look.
>Fearow
New Moves: First Impression, Swords Dance, Dual Wingbeat, Last Resort, Tailwind, Knock Off, Taunt, Switcheroo, Power Trip, Feint, Double Edge.
First Impression's Japanese name is "Head-On Collision", which generally fits its dex

[10] Cobblemon 1.7 Release!
by shadowboxed on Nov 22, 2025
Download
This version is meant to be used with Cobblemon 1.7! Fixed Color Change & Diglett. Please keep in mind that some mons with certain functions might not work properly, I'm getting to work on it right now. Abilities and moves have been moved to the proper folders. Please let us know if anything's not working like it should.
[8] Shadow Force fix & Friend Guard
by shadowboxed on Nov 14, 2025
Download
Probably about time we got this update going!
This new version of Project Lazuli fixes the Shadow Force bug that was stuck there for a while (battle crashing), alongside fixing Hisuian Avalugg's stats for it to be like it is in the document. It also adds a new function to the Friend Guard ability for you singles players.
This mean that in Doubles/Triples it retains its usual function, but in single battles, switching out reduces damage to the Pokemon that switched in will reduce damage done to it by 25% for that turn.
With Cobblemon 1.7 coming out VERY soon, we're gonna be focusing on making sure that everything's ready for a proper port to it ASAP. It should go along smoothly, but still, please report any bugs you see either on our Gitlab or our support thread.
