How to Get Free Orundum in Arknights
Every Arknights player asks the same question: where does the free Orundum actually come from? Here are the 10 sources ranked by size, with the exact monthly numbers behind each one.
The monthly total
A committed F2P player earns ~36 pulls per month (≈21600 Orundum) from the sources below. The Arknights Income Calculator lets you toggle each source to match your playstyle.
Ranked sources
1. Events (biggest) — every patch ships 1-2 events worth 2,000-4,000 Orundum. Always complete them; they're time-limited income.
2. Dailies — 60 Orundum/day = 1,800/month. Ten minutes a day, the most reliable source in the game.
3. Endgame modes — weekly/rotating content (abyss-style, simulated universe-style, total war, etc.). Full clears add 1,200-1,600/month.
4. Free battle pass — the no-purchase track pays ~800 Orundum equivalent (5 pulls) per patch. It's free, so just play it.
5. Maintenance & stream compensation — servers break, devs pay: ~900 Orundum/month in global server apologies and live-stream codes.
6. Exploration / story — one-time but massive: new regions ship 2,000-5,000 Orundum in chests, quests and puzzles. Save these for when you're short.
7. Redeem codes — the official codes (see the Arknights Redeem Codes page for the current list) add a few hundred Orundum every patch. Check it weekly.
8. Shop exchange — stardust/starglitter-style shops convert pulls' 4★ duplicates back into currency. ~200-400/month, scales with pulling.
9. Achievements — permanent Orundum in the codex. Browse the achievement list once a month and clean up stragglers.
10. Web events & mini-games — anniversary and collab periods add 500-1,500 Orundum in one-off web events. Watch the official channels during patches.
The strategy: stack the reliable ones
The first five sources are predictable (~80% of your monthly income) — plan around them. Sources 6-10 are bonuses — treat them as top-ups for banner windows, not baseline.
