Artifact Crafting

Craft artifacts in the Forge from enemy materials, merge three of a kind to raise their tier, and forge a Legendary from three Tier III.

Artifacts are crafted bonuses that you socket into equipment. The Forge turns enemy materials into artifacts of your choice.

Materials

Specific enemies drop specific materials (bosses drop Boss Cores at a much higher rate)
Material drops start at wave 10
Storage cap per material: 200, +15 per Awakening level

Tiers

Crafted artifacts start at Tier I. Merging three identical artifacts of the same tier creates one of the next tier, up to Tier III. Three Tier III artifacts can be forged into one socketable Legendary (Tier IV) artifact.

Legendary (Tier IV)

Forged from three Tier III artifacts, and socketed like any other artifact
The component you pick FIRST is the base: it contributes 100% of its rolled value
The other two contribute 50% of their rolled values each
If all three are the SAME artifact, add a further +25% of the base's rolled value
Secondary effects (an artifact's rider) carry over at the same weights

Worked example

Bone Rune rolls between 14% and 22% max HP at Tier III. Fusing three of them rolled at 22%, 19% and 16%, with the 22% picked first as the base:

22% × 100% = 22.0%
19% × 50% = 9.5%
16% × 50% = 8.0%
same-artifact bonus: 22% × 25% = 5.5%
Total: 45.0% max HP — against 22% from the best single Tier III.

Fuse three DIFFERENT artifacts instead and you get one socket carrying three separate effects, at 100% / 50% / 50%. Same rule, different goal: raw power on one stat, or three effects in one socket.

Order matters — the base is read for both the 100% weight and the same-artifact bonus, so always pick your highest roll first. And a Legendary counts as EVERY effect it carries: fuse three different artifacts and all three of those effects are spent for your whole loadout. It saves sockets, not the one-per-effect budget.

Reforging rerolls an artifact's value within its tier range — cheap insurance against a bad roll.
