Void units: variants and value limits

A Void label changes which item you are discussing. It does not supply a trade multiplier or prove that a base unit estimate applies to that copy.

What the available evidence shows

MeddysonTD’s September 19 crafting narration discusses Void and Shiny outcomes and variant copies. The Backrooms walkthrough also narrates variant openings. These creator observations support discussing variants without establishing current odds or stat multipliers.

Our recorded market rows are base-named source items. The source does not establish a complete set of independently priced Void variants for this site. A missing variant estimate is unknown, not zero.

Before pricing a Void trade

  1. Read the exact unit name and variant tag in the live inventory and final trade screen.
  2. Find a source record that explicitly matches that variant and date.
  3. Keep its price separate from the base-named row; do not apply an invented 2×, 5× or 10× factor.
  4. If no matching record exists, negotiate with the uncertainty visible rather than using a guaranteed win/loss verdict.

Before crafting or consuming a variant

Inspect whether the recipe requires or accepts a particular variant. A creator obtaining a Void result on one attempt does not establish a recipe-wide guarantee.

Keep the copy you use to clear maps until you have checked which ingredients will be consumed. Record the live recipe and result instead of relying on an existence counter or a similarly named base unit.

Calculator boundary

Both calculator snapshots publish supported source estimates for their named records. Neither automatically converts a base value into a Void value. If your copy is a variant without a matching record, leave it unpriced rather than selecting the base unit and calling the result exact.
