Collect 1 Million Items Catalog: Rarities & Index Rewards

Items spawn with progressive rarity tiers: Common, Rare, Epic, Legendary, Godly, Exclusive, and Secret. Items also roll special mutations (Golden, Dark Matter, Prismatic, Frozen) that multiply Cash void value. Registering newly discovered high-tier items in your collection index awards one-time Gem rewards, fueling your ability rolls.

Rarity hierarchy

Item Rarity Hierarchy (Common to Secret)

Ordered highest to lowest by Void Cash Multiplier. The multiplier is what the tier pays when an item crosses into The Void; the Gem reward is the one-time payment for registering it in the collection index.

Mutations

Special Item Mutations & Value Multipliers

A mutation is a roll on top of a tier, not a tier of its own — which is why these four are listed separately rather than ranked against the table above.

GoldenRolls onto a spawned item and multiplies its void Cash payout.
Dark MatterA darker variant of the same roll; multiplies void Cash and changes the item's look.
PrismaticThe rainbow variant. Same rule: the base item keeps its tier, the payout is multiplied.
FrozenAn icy variant that multiplies the payout on the same void entry.

Mutations multiply void Cash value up to 10x. The game does not publish a separate multiplier per mutation, so this page does not print one.

Gem economy

The Index Reward Gem Economy

The Collection Index is the primary non-Robux source of Gems: discovering high-tier items awards between 5 and 50 Gems per entry. That makes the index the cheapest route into ability rolls, and it is why the rarest tiers are worth chasing even before their Cash multiplier matters.

Every entry pays once per account. A tier you register on day one keeps paying you nothing afterwards, so the early tiers are a one-time boost rather than a farm.

By situation

Best choices by situation

Maximum Cash Payout

Secret Item

Less than 0.01% base spawn rate.

Watch out: Requires stacked Rebirth Luck multipliers and Prospector ability to find.

Sustainable Midgame Value Farming

Epic Item

10x multiplier is solid but requires steady platform clearing.

Watch out: Mutated variants (e.g. Prismatic Epic) can match base Legendary payouts.

Early-Game Index Gem Influx

Rare Item

Awards only 1 Gem, but spawns frequently enough to complete early index tiers.

Watch out: Common items provide zero Gems upon registration.

Questions

Item and rarity questions

How do item mutations work?

Spawned items have a small chance to roll mutations such as Golden, Dark Matter, Prismatic, or Frozen, multiplying void Cash payouts. The mutation stacks on top of the item's own tier, so a mutated Epic can pay like a base Legendary.

How do rare items generate Gems?

Discovering new high-rarity items registers them in your collection index, awarding one-time lump-sum Gem rewards. Each entry pays once per account, which is why the early tiers are worth clearing even though their multiplier is small.

Which tier should I hold out for?

It depends on the wall you are at. Before 10,000 items the bottleneck is throughput, so any tier you can repeatedly push pays better than a rare one you meet once. Past 100,000 the Cash multiplier on a high tier starts to matter more than the count.
