Polished Slab is a metal crafting component linked by its localized description to demi-humans and weapons that require accuracy. No exact enemy, floor, recipe or drop rate is verified yet.

Use demi-human encounters as a source category to test, not as proof that every demi-human drops it. Confirm Polished Slab by name in the post-battle loot list before repeating a route.

What Polished Slab is

A fragment of metal meticulously polished by demi-humans. It has been buffed with obsessive thoroughness. A seemingly perfect crafting component for weapons requiring accuracy.

Simplified Chinese name打磨过的板片

The description is useful for identifying the material family and likely source category. It is not enough to publish a precise map pin or drop percentage, so this page separates confirmed item data from route leads.

Where to get Polished Slab

Use demi-human encounters as a source category to test, not as proof that every demi-human drops it. Confirm Polished Slab by name in the post-battle loot list before repeating a route.

  1. Record the exact demi-human enemy and quest area.
  2. Confirm the material name in the loot result.
  3. Repeat the same encounter and note the current game version.
Fast verification rule: one screenshot can prove that a drop happened; two or three repeated runs are needed before calling a route dependable. Keep the game version and Cardinal Rank with the note.

Polished Slab recipes and uses

Result or useAmountEvidence note
Accuracy-focused weapon craftingNot listedThe localized description identifies this broad use; no exact Smithy recipe is verified.
Metal crafting componentNot listedThe record describes a meticulously polished metal fragment.

Community recipe indexes are useful for planning a shopping list, but the live Smithy remains authoritative for availability, cost and whether a blueprint or Cardinal Rank gate is still missing.

Farm without wasting a quest

  1. Open the Smithy recipe first and confirm how many copies are needed.
  2. Activate the nearest Safety Area or Warp Terminal before testing a route.
  3. Fight the smallest repeatable enemy group that matches the current source clue.
  4. Check the loot notification after every run and stop if the expected material never appears.
  5. Return with enough material for the recipe rather than filling inventory without a target.

Polished Slab FAQ

Is there a confirmed drop rate?

No verified rate is present in the current local export. A percentage should only be added after a versioned drop table or a sufficiently large repeat test is available.

Why is the material not at the Smithy?

Owning a material does not guarantee that every related recipe is already visible. Recipe availability can depend on discovered blueprints, story progress, towns and Cardinal Rank.

Should I sell spare copies?

Keep enough for the recipe you are actively targeting and avoid selling the last copies of a material whose acquisition route is still uncertain.

Evidence boundary: the name, localized description and record ID come from Steam demo build 23442858. Community recipe information is labeled separately; exact full-release acquisition remains subject to verification.
