Nuggets


 * "A piece of ore that can be refined relatively easily to obtain metal needed to create defense gates."

Nuggets are common materials like the Shards that are used for defense gates. These look like large chunks of crystals all together with a blue shine to it. Each nugget builds the defense gates 5% each, in total, 20 nuggets makes one defense gate. This is the same material to make Rails in Dillon's Rolling Western: The Last Ranger.
