Collection Index
Backpack space grows from Index claims, not a shop purchase — new material types count; duplicates do not.
By Bloxron Editorial Team · Last updated
Collection Index logs distinct material types you have picked up. Hitting a milestone unlocks a chest that adds one backpack slot — storage grows this way, not from a shop purchase. Exact milestone numbers shift in Beta, so read the live Index line; we do not publish a frozen X/Y sheet here. If the bag caps every run, fix Index before pouring coins into the next wand buy or armor multiplier.
Increase backpack storage
Check the target
Open Index from the hub (often the book icon on the left menu). Note Currently Collected and the milestone line (format: Complete X/Y to get +1) near the reward chest — exact X/Y numbers are only reliable in that UI.
Hunt new types
Enter the dungeon, walk onto drops, and interact to pick them up. Log material types you have not seen yet — missing entries may show as ???.
Skip duplicates
Only new types count — copies of known materials do not move the milestone.
Claim and confirm
Return to the hub, open Index, and use Click to claim when the chest shows +1. A successful claim shows “Backpack storage increased by 1” and capacity ticks up one slot (for example 0/4 → 0/5).
Chest stays locked until the distinct-type count hits the listed target. Some milestones may need discoveries beyond raw drops (for example a new brew) — trust the Index line. Push later dungeon stages when early floors stop dropping new types. First-hour order lives on the beginner guide.
