Adamantite cannot be obtained by defeating enemies, and the only way to farm it is by destroying blue asteroids in specific Gummi Ship routes (Misty Stream or The Eclipse). It is also found in specific treasure chests and treasure spheres, but these are one-time-only locations.

The best spot for farming Adamantite is in The Eclipse Gummi Ship route, where asteroids will drop Adamantite at a 1.5% drop rate.

The Eclipse Farming

The Eclipse is the best Gummi Ship route to farm Adamantite.

You can obtain this material by blasting blue asteroids while flying inside the route. To get started, open your World Map and enter The Eclipse route by embarking from the Keyblade Graveyard.

As soon as you arrive in space, you’ll see a colossal battleship close by.

Just veer a little to the side of the ship to find a large cluster of blue asteroids.

Shoot these asteroids to receive various Gummi Ship parts and synthesis materials, including the Adamantite.

Adamantite is rare, only dropping 1.5% of the time from the asteroids in The Eclipse.

But it’s the highest drop rate you’ll get. So just keep blasting apart as many blue asteroids as you can and eventually your Adamantite haul will start tallying up.
