Floors, Rock Rarity and the Index

§Read the room-specific rock panel#

Each reviewed floor panel lists its possible rock types and percentages below the durability bar. Room 5 shows Uncommon, Rare, Elite and Nova Prism entries. Other rooms show different distributions.

Use the panel for the room you are actually farming. Do not apply one screenshot’s percentages to every floor or multiply them into a material drop chance. Rock availability and the material obtained by cutting are separate stages.

These are the percentages printed in the reviewed room panels. They total 100.1%, so do not normalize them or assume a verified random-roll formula. The footage does not settle rounding or whether Nova Prism uses a separate roll. The table describes rock availability in those rooms, not the materials produced by a cutter.

§Balance depth with collection time#

Deeper panels in the recording have substantially larger durability totals and different rock selections. The best practical target is a room you can break and refill from reliably with your current equipment.

If progress stalls at a floor, return to Power training, inspect pickaxe requirements and keep existing machines working. The exact best room depends on current equipment and the material you want.

Room 5 displays a total floor durability of 6.41M in the reviewed frame. Room 7 shows a much larger bar, but the player obscures part of its total, so no exact Room 7 durability is transcribed. Compare the visible bar with your actual damage and collection turnaround before committing to a deeper room.

§Check Index rewards as your collection grows#

The official description links Index completion with aura unlocks. An INDEX button is visible on the left of the gameplay interface. Open it to inspect the entries and requirements currently available to your account.

The reviewed frames do not show the full Index or aura effects. Exact completion thresholds, stacking rules and a best-aura ranking remain unverified.
