Artifacts

Artifacts are humming idols pulled from the deepest caves — one for each biome. They serve as Arena keys: to challenge a biome's guardian in an Alpha Arena rematch, you must spend that biome's artifact as tribute. There are ten artifacts, one per biome.

How to obtain artifacts

• Artifacts drop only from cave delves — a small chance (about 1.5%) on each winning delve of that biome's cave.
• Because they are cave-only, farming artifacts means repeatedly clearing the cave of the biome you need.
• Artifacts are sellable for Amber, but since they are also your Arena keys, selling them is a choice with a cost.

How artifacts are used

Each Alpha Arena rematch is fought at that guardian's own biome and consumes the matching artifact:

• A standard arena attempt spends one artifact.
• An Alpha-tier attempt spends two.

You therefore need a steady supply of a biome's artifact to keep challenging its Arenas — and the Arenas are where the endgame Primal set is won.
