Cobbleverse does not use one universal legendary-spawn rule. Some Pokémon wait in generated structures; some require a radar and a separate altar item; some are natural spawns near a landmark; and others use eggs, cloning machines, portals, or dedicated dimensions. Start with the method in the inventory below, then follow the linked walkthrough for the exact recipe, location, level, and trigger.

Before leaving, carry capture supplies, healing, the exact required item, and the travel support named by that walkthrough. If a structure is involved, read Structures and Radars before treating a map marker as an entrance or assuming another legendary's locator recipe applies.

This table is reviewed against all 38 canonical entries in the generated legendary index. “Structure encounter” means the Pokémon is found as part of the structure route; it does not imply a shared altar or spawn trigger.

A radar narrows the structure search; it does not replace the encounter prerequisite. Ho-Oh still needs the Rainbow Wing, Kyogre still needs the Ocean Core, and Dialga still needs its orb and Red Chain sequence. Open the exact walkthrough before crafting because recipes, cartography tables, dimensions, and biome constraints vary.

The Structures and Radars guide explains the common map-reading and failure checks. The parser-backed Locator Chip page is the maintained source for the component used by the general Poke Radar.

An altar may consume or transform a prerequisite, produce a reward, or lock an alternative. Dialga demonstrates an ordered sequence: place the Adamant Orb first, then use the Red Chain. Regieleki and Regidrago demonstrate a choice: activating one altar removes the other in that temple.

The Legendary Beasts and Galarian Birds are documented conditional natural-spawn groups, not altar summons. Their guide data identifies separate time or weather modifiers. A multiplier changes relative selection; it is not a guaranteed spawn or a published catch-rate promise.

Mewtwo is produced through a multi-block cloning setup. The machine has its own materials, loading order, progress display, and variant catalysts; a radar or generic altar item is irrelevant.

Use the comparison table as the canonical inventory, then follow one walkthrough from start to finish. For regional requirements, confirm the active checkpoint in the Progression Overview. For recipes and live acquisition sources, follow the linked Items directory rather than copying a screenshot's price or drop list.
