Source notes
Dataset version 2026-09-09. Drop rates are re-verified against the cited sources before each version bump; the version string is the verification date, not the publish date.
What is in the file
One row per blook. 15columns covering pack identity, pack cost, rarity, drop rate, sell value, and three precomputed confidence thresholds. The threshold columns are the ones worth having — they answer “how many packs until I actually get this?” without anyone needing to run the maths themselves.
| Column | Meaning |
|---|---|
| pack_id | Stable pack identifier used across the site and API. |
| pack_name | Display name of the pack, e.g. Spooky. |
| pack_cost_tokens | Token cost of one pack opening. |
| pack_status | live if the pack is currently purchasable, otherwise locked. |
| blook_id | Stable blook identifier, prefixed with its pack id. |
| blook_name | Display name of the blook. |
| rarity | Common, Uncommon, Rare, Epic, Legendary or Chroma. |
| drop_rate_percent | Chance of pulling this blook from one pack, in percent. |
| sell_value_tokens | Tokens returned when the blook is sold. |
| packs_for_50pct | Packs needed for a 50% chance of at least one. |
| packs_for_90pct | Packs needed for a 90% chance of at least one. |
| packs_for_99pct | Packs needed for a 99% chance of at least one. |
| tokens_for_90pct | packs_for_90pct multiplied by pack_cost_tokens. |
| blook_url | Canonical page for this blook. |
| pack_url | Canonical page for this pack. |

How the thresholds are calculated
Each pack opening is an independent trial, so the chance of getting at least one copy of a blook in n packs is 1 − (1 − p)n. Rearranged for the number of packs:
packs = ceil( ln(1 − confidence) / ln(1 − dropRate) )
The published figures assume no duplicate-refund discount. Refunds depend on which blooks a player already owns, so any single number we printed would be unreproducible for most readers — the plain figure is the one anyone can check. Use the chase calculator to model refunds against your own collection, and the methodology page for the full derivation.
