Blood Shards for Kadala gambling
Blood Shards let you target a specific equipment slot at Kadala when pursuing a missing set piece or legendary.
Blood Shard drops from Rift Guardians and Horadric Caches; Kadala is in town in Reaper of Souls Adventure Mode.
Repeat the earn-and-spend loop without a fixed limit; there is no guaranteed item on any purchase.
Stop spending when the target item is acquired or your build needs a different slot; switch to farming the source that supplies your next bottleneck.
Open a guide to find other locations and see what the item is used for.
