Radiant Shards are a type of Resource found in the Radiant Ruins biome through completing Dark Heart lairs, killing Radiant Giants, or from opening Radiant Caches. They are primarily used in crafting items at the Runecrafting Bench.
Radiant Shard gains from Dark Heart lairs are doubled (or tripled for Patrons) during Friday's Daily Bonus, making farming them and selling them on the Player Marketplace a good way to earn Flux on that day.
