Drill for Anime Collection and Unit Index

Many Roblox drill collectors treat the unit index — a catalog of everything you have pulled — as the long-game goal beside cash charts. Drill for Anime by Nomel Studios follows that pattern at a high level: you drill, fight or roll anime-style units, level them for passive income, and keep collecting as deeper layers and Lucky Blocks expose higher rarities. This guide explains collection as progression, what to do with duplicates when rules are unclear, and which index rewards we cannot confirm until official sources document them.

Income-first players should still read Earn Faster and the Tier List. Collectors should pair this page with Rarity Guide labels.

Collection versus income: two valid goals

Drill for Anime supports at least two playstyles within the same loop:

Goal	Focus	Primary pages
Income	Level highest rarity, push depth, optimize offline	Earn Faster, Offline Earnings
Collection	Fill index slots, chase missing rarities, keep dupes for future systems	This guide, Lucky Blocks

Neither invalidates the other. A collector who ignores drill upgrades stalls on depth gates (Depth and Zones). A min-maxer who ignores index progress may delete dupes that later matter if Nomel adds conversion or index bonuses.

How units enter your collection

Confirmed high-level sources at wiki time:

1. Fights while drilling — see Character Fights.
2. Lucky block openings — variance path with disputed promo ties on the Codes hub.
3. Possible shop or event grants — verify after patches on Updates and Discord.

We do not invent specific character names tied to real anime IPs. Record units by rarity tier, income stat, and fight helper tag until official rosters stabilize.

What an index likely tracks

Drill simulators commonly show:

• Silhouettes or locked slots for units not yet obtained
• Checkmarks for owned entries
• Rarity filters (Common through Epic and higher live tiers)

If Drill for Anime exposes a dedicated Index or Collection UI, screenshot it after each patch. We will align this guide when Nomel Studios names the screen publicly. Until then, treat any in-game catalog button as your index.

Duplicates: honest unknowns

When you pull a unit you already own, games usually do one of the following — we cannot confirm which applies to Drill for Anime without official text:

• Auto-convert duplicate into cash or shards
• Stack duplicate as upgrade fodder for the original unit
• Leave duplicate as a separate inventory copy with no benefit
• Feed a future trading or fusion system not announced at launch

Safe practices until clarified:

• Do not discard or quick-sell dupes if the UI warns about permanent loss.
• Keep one leveled copy for income; store extras if inventory allows cheaply.
• Ask in official Discord before mass-selling during patch week.
• Avoid Brainrots duplicate advice — wrong economy (vs Brainrots).

When Nomel documents duplicate rules, we update Updates and this section together.

Index rewards: confirmed vs speculation

Some games grant global buffs, titles, or currency for index completion percentage. No verified public post from Nomel Studios at wiki time promises specific index milestones for Drill for Anime. Treat completion rewards as unknown, not guaranteed.

Reasonable expectations (not promises):

• Collection progress may tie to achievements or UI flair even without stat buffs.
• Future updates could add index bonuses — common in genre peers.

Play for units you enjoy visually; fund the habit with income play so collection does not bankrupt drill upgrades.

Rarity-first collection strategy

Use Rarity Guide vocabulary:

1. Secure one strong income unit per rarity band you can access.
2. Index hunt missing rarities at your current depth before gambling deep-block funds.
3. Open lucky blocks when infrastructure supports leveling any spike (Lucky Blocks).
4. Push depth when index slots stall — shallow farms rarely complete higher tiers (Depth and Zones).

Tier List ranks power; this guide ranks completion order when you care about the catalog.

Collection and offline earnings

Indexed units only help offline income if they are leveled and counted in passive formulas. A full index of level-one commons loses to a partial index with one Epic grinder. Read Offline Earnings before chasing silhouettes instead of levels.

Codes, blocks, and collection spikes

Disputed codes LUCK26 and EPIC may inject cash or blocks (Codes hub). EPIC is widely reported to include an Epic-tier block — useful for index jumps if redemption works. Official Code Zone (1 August 2026) noted no codes menu on some builds; without redemption, collection pace stays fight- and grind-driven. See Codes Not Working.

What we deliberately omit

• Trading player-to-player — not confirmed for this guide scope.
• Rebirth systems — not documented for Drill for Anime here.
• Named anime IP characters — patch-dependent and legally sensitive to invent.
• Fake index percentages — we do not publish completion stats we cannot measure live across accounts.

Collect with eyes open. Until duplicate and index rules are official, keep proof screenshots and favor flexibility over quick sells.
