Act Materials & Attunement

The act adds two materials of its own. Celestial Filament (World 7) and Echo Shard (World 8) do not craft new artifacts — they feed ATTUNEMENT, a permanent rank system on your maxed artifacts that only pays off inside the act.

Where they drop

• Celestial Filament — a rare drop from World 7 Choir Voices
• Echo Shard — dropped only by the World 8 Rimewarden elite (the frost Ent); no other enemy drops it
• There is no conversion between the two — each is farmed in its own world
• Corruption increases dropped amounts; the standard 200-per-material storage cap applies

Artifact Attunement

A Tier III (maxed-tier), non-Legendary artifact with an eligible effect can be attuned at the Forge, up to rank 10. Each rank permanently raises the artifact's rolled value by 1% (relative — +10% at rank 10), but the bonus is ACTIVE IN WORLDS 7+ ONLY: in Worlds 1-6 the artifact behaves exactly as if unattuned. Attunement costs only materials — no diamonds, no randomness; a rank can never fail or be lost.

Lifecycle rules — read before investing

• Reforging (rerolling the value) KEEPS the attunement rank
• Merging three artifacts into a higher tier RESETS attunement — the merged artifact starts at rank 0
• A Legendary forge requires all three components at the SAME rank and inherits it; mixed ranks are refused before anything is consumed
• The Jewelry forge refuses attuned artifacts entirely
• A socketed artifact cannot be attuned — unsocket it first
