Cobblemon: Legends Untold

Rayquaza appears at the Sky Pillar, a rare structure found in mountain biomes, once a player brings a Jade Orb to its top, where a level 70 Rayquaza spawns. Mew is placed in the Faraway Ruin, a rare structure in jungle biomes, and entering it spawns a level 30 Mew, while Xerneas appears near the Tree of Life in oak forest biomes at level 50. Each of these can be caught by only one player per server. Rare loot in legendary structures includes Mew DNA, which together with a nether star or comet shard can be used to create Mewtwo in a Resurrection Machine.

The Legendary Birds roam any biome and spawn three times less often than starter Pokémon. Articuno's spawn chance doubles during rain, Zapdos's during storms and Moltres's during clear weather. Walking Wake and Iron Leaves are found in Tera Dens, a new underground structure that comes in water and psychic variants, and appear at level 75 near the den's center. The mod adds five structures and seven items in total.

Cobblemon: Legends Untold is a server-required mod: it has to run on the server, while clients may leave it out. It is built for Cobblemon, so the Cobblemon mod is a required dependency, along with TSFlareon's Item Core. Files are published for Fabric, Forge, NeoForge and Quilt, covering 1.20.1 and 1.21.1, and the content is released under CC0 1.0 Universal, which is not open source.
