Radiant Caches can be obtained by rare drops when defeating Radiant Giants. The cache can be opened like an Ally Soultrap, and grant the player a random item. The in-game description warns that the contents of Chaos Chests can and will change at any time, with no indication of what they contain. So far, most players have reported getting crafting materials from these chests. Players have been known to have received rare items such as a Radiant Seeds and the rare mount Radiant Steed.
