The INDEX button and interface layout
In the guide video, the main HUD presents four core navigation buttons grouped together on the lower-left edge of the screen: SHOP, BACKPACK, INDEX, and DAILY REWARDS. Clicking INDEX opens the collection log that catalogues your discoveries.
Whenever your cutter finishes processing an unfamiliar rock, a banner notification appears across the screen. For example, the guide video captures a discovery banner reading New material! 2/4 Rose Quartz / Uncommon. This confirms that individual mineral varieties track sub-tier completion counts along with designated rarity tiers.
The official aura promise and the 24-entry milestone
The developers outline the primary incentive for cataloguing rocks in the official Roblox game description: Complete your Index and unlock powerful auras!. While this confirms that auras exist as a mechanic tied to collection progress, the store documentation provides only one specific numerical requirement across the entire game.
That benchmark appears in the official listing for the 200x Anvil game pass, which advertises training on the station without completing 24 Index entries. This single line confirms that reaching 24 Index entries grants access to the top anvil in the AFK training area without spending Robux. If you want to bypass that requirement with currency, you can review the station multipliers in the power and anvils guide or examine the pass price in the official game passes section.
Confirmed facts versus unconfirmed aura mechanics
Because community wikis and third-party databases often mix speculation with confirmed game data, separating verified features from undocumented systems helps prevent wasted time.
| Category | Confirmed by Official Sources | Unconfirmed / Missing Public Data |
|---|---|---|
| Index Button & HUD | Positioned on lower-left HUD beside SHOP, BACKPACK, and DAILY REWARDS | Total number of pages or categories within the Index menu |
| Entry Tracking | Displays discovery popups such as New material! 2/4 Rose Quartz / Uncommon |
Complete catalog of every collectible material and sub-variant |
| Progression Gates | 24 entries unlock the 200x AFK training anvil without a pass | Any milestone thresholds beyond the 24th entry |
| Aura Rewards | Official listing confirms completing the Index unlocks powerful auras | Specific aura names, visual designs, and rarity distributions |
| Aura Stat Effects | Linked directly to collection completion | Multipliers, stat percentages, damage boosts, or whether auras stack |
No public source publishes aura names, stat tables, or total entry counts. We do not invent placeholder lists or quote unverified forum posts for these mechanics.
Why Index progression requires mining variety over static tables
Filling out 24 entries in Cut a Rock depends on breaking different types of rock instead of repetitive farming in early rooms. Each mining room presents a specific distribution of rocks. For instance, Room 2 lists Common at 50%, Uncommon at 50%, and Nova Prism at 0.1%, while Room 3 introduces Rare at 15% alongside Common at 35%, Uncommon at 50%, and Nova Prism at 0.1%.
Players who stay in Room 1 or Room 2 will quickly discover all available local variants, causing Index progress to halt. To log new entries, you must advance through floor barriers like Locked - 100$ and Locked - 1K$ to enter new chambers and harvest unfamiliar deposits. You can inspect the room distributions in the rock rarities overview to identify which chambers yield uncollected materials.
Once a fresh rock is excavated, transport it to the cutting machines. Discoveries register only after the cutter completes its timer and you collect the processed mineral into your backpack.
