Cobblemon - Genesis Forms

The mod works as an all-in-one gimmick forms handler for Cobblemon. It adds Mega Stones, Mega Accessories and the Key Stone, along with Mega Rayquaza's Dragon Ascent move, and it can make Mega Evolution work outside battles, which server owners can switch on or off. Custom Mega Stone support lets additional stones be registered alongside the built-in ones, and the mod also covers Legends: ZA Mega Stones, a Mega Crystal and a Mega Shard.

Terastallization is handled through the Tera Orb and Tera Shard items, and a fix corrects the Tera type of Terapagos and the mask-based forms of Ogerpon. Dynamax content covers the Dynamax Band, Max Soup, Max Mushrooms in item and block form, and Dynamax Candy. Z-Move items include Z Crystals, the Z Ring and the Z Power Ring, and Memory Discs are included as well. The mod also adds Rotom appliance forms and held items such as the Adamant Orb, Lustrous Orb, Macho Brace and Soul Dew.

Cobblemon and Fabric API are required, and Polymer is required too. The mod is server-side only, so the server needs it and players join without installing anything.
