⚠️Warning! I highly reccomend building a box or large platform around sky pillar so that Rayquaza can't fly away and despawn because he tends to do that

Monuments of Hoen is a Cobblemon addon that adds structures to spawn in legendary Pokemon.

To do this the mod utilizes items from Mega Showdown as summoning items: https://www.curseforge.com/minecraft/mc-mods/cobblemon-mega-showdown

Right now it adds the following Pokemon in the following structures:

Rayquaza summoned at Sky Pillar (hoenmonuments:sky_pillar) found in desert biomes, by right clicking one of the two Jade Pedestals with the new Jade orb item added by the mod crafted with 4 (Mega Showdown) Dragon Tera Shards and a Nether Star:

Kyogre can be spawned by rightclicking on the Marine Pedestal in the Marine Temple structure with a Blue Orb item from Mega Showdown (hoenmonuments:marinetemple) found in deep oceans

Finally Groudon can be spawned by rightclicking on a Terra Pedestal with Mega Showdown's Red Orb item in the Magma Shrine structure which spawns in Nether Wastes biomes (hoenmonuments:magma_shrine)

Note: This structure does have some weird spawn quirks like spawning on a floating island or hidden inside netherrack so I might change that in a later update, that being said the structure is completly functional

To find the structures you can install the mod Omnicompass, when Omnicompass is installed this mod adds 3 custom compasses to the game to find the different structures. When you install it please make sure to disable the structure and biome compass item in the omnicompass config file for the optimal gameplay experience: https://www.curseforge.com/minecraft/mc-mods/omnicompass

Important stuff:

You can summon one of each legendary per player per world, unless you have the legendary monuments mod installed: https://www.curseforge.com/minecraft/mc-mods/legendary-monuments-cobblemon then you will be able to spawn multiple using the medallion of renewal item from that mod

This mod also uses the mod Chipped for building blocks used in the new structures: https://www.curseforge.com/minecraft/mc-mods/chipped

If you have any suggestions for more legendary structures let me know in the comments
