Definition
Packs are loot boxes purchased with tokens in the Market. Each pack contains a fixed pool of Blooks across rarity tiers, and opening one pack gives you exactly one Blook drawn according to the pack's published drop rates.
Packs come in three flavours: Market packs (always available), Seasonal packs (rotate by event — Spooky, Blizzard, Lovely, Lucky, Spring, Autumn), and Hidden / Free packs (limited-time drops, usually free).

How pack math works
Drop rates within a pack always sum to 1.0 — every pack opens to something. The rates are split across tiers (Common / Uncommon / Rare / Epic / Legendary / Chroma) and within a tier they're further split among the individual Blooks.
If a pack's Chroma tier rate is 0.0015 and three Chromas share that tier with weights 8 / 5 / 2, the per-Blook drop rates are 0.08% / 0.05% / 0.02%. Each pack opening is independent — opening 100 doesn't increase the next pack's odds.
