How to Farm Crystals of Aurora Fast in Mobile Legends
Updated at: 5/28/2025

Ever wonder how some players casually spend on Grand Collections like it’s part of their login routine? How they're unlocking world collector skins with ease? Truth is—there’s a smart way to farm Crystals of Aurora (COA) consistently, and it doesn’t require breaking the bank.
Hi, it’s Gener8ify , and today I’ll break down a guaranteed method to farm Crystals of Aurora every month. Whether you’re a budget player or a light spender looking for value, this guide will help you maximize your farming potential.
What Is Crystal of Aurora (COA)?
For the uninitiated, Crystal of Aurora is a premium Mobile Legends currency similar to diamonds—but it works specifically in certain draw systems like:
Zodiac Summon (e.g., Cancer, Gemini skins)
Aurora Summon (occasionally Venom skins)
Magic Wheel (main path to Legend skins)
New Arrival Draws
Grand Collection (Collector skins)
You might ask: “If diamonds and COA can be used the same way, why bother farming COA?”
Here’s the trick: Diamonds are your active currency—used for events, skins, and dailies. But COA is your passive currency. It’s the forgotten $100 in your jacket pocket. You’re building a second wallet, silently accumulating wealth for future skins.
Benefits of Farming COA
Farmable long-term currency
Doesn’t drain your main diamond stash
Great for prepping future events or Collector skins
Gives flexibility when you’re low on diamonds

Final Thoughts: Save Smart, Spin Smarter
A full Grand Collection cycle might need 3000–4500 Diamonds, and even more for a Magic Wheel pity unlock. But if you're farming 1200 COA/month, then in just 3 months, you'll have 3600 COA—enough for a full Collector skin spin without touching your main diamonds.
COA is your long-term savings fund for big skin targets. So instead of blowing diamonds impulsively, let your COA do the heavy lifting while you save diamonds for important limited-time events.
