What are Crystal of Aurora Used For?
Crystal of Aurora is a distinct, star-shaped currency that appears in the inventory menu and the top bar of the main lobby, sitting alongside Gold and Diamonds for easy tracking. It works on a 1:1 basis with Diamonds inside select draw events, including Zodiac Summon, Aurora Summon, and the Grand Collector event, all accessible through the Shop's Draw section. When a draw is made, the game automatically prioritizes available CoA first, only pulling from the Diamond balance to cover any shortfall. It cannot buy heroes or regular skins directly, and it cannot be gifted or traded to other accounts, but it never expires, making it completely safe to stockpile ahead of a target event without any pressure to spend it right away.
Proven Ways to Get More Crystals of Aurora
Tip 1: Claim the Weekly Diamond Pass Daily
The Weekly Diamond Pass is the most consistent CoA source in the game. Subscribing grants a small Diamond bonus each day along with a Choice Bundle, which includes an option worth 10 CoA daily. Selecting this option every single day, rather than the alternative rewards, is essential for steady CoA growth.
Tip 2: Use the CoA Daily Supply
Located in the shop's Special section, the CoA Daily Supply costs only 10 Diamonds and returns between 10 and 50 CoA per purchase. Even the lowest outcome breaks even, while higher rolls multiply Diamond value several times over. Checking this supply daily is a low-risk habit that pays off over time.
Tip 3: Grab Both Monthly Supplies
Two dedicated monthly bundles exist purely for CoA. The Monthly Supply converts 99 Diamonds into up to 300 CoA, with a guaranteed floor of 120 CoA. A 20-Diamond coupon can lower the price to 79 Diamonds, improving the value further.
The second option, a smaller Monthly Value Pack, costs 15 Diamonds for a flat 30 CoA, effectively doubling Diamond value. Both bundles refresh only once a month, so timing purchases early is important.
Tip 4: Subscribe to the Starlight Membership
The Starlight subscription grants 300 CoA over its duration, on top of the exclusive monthly skin and other perks already included. This effectively converts 300 Diamonds into 300 CoA while still delivering full Starlight benefits, making it one of the highest-value sources on this list.
Tip 5: Build a Structured Monthly Routine
The biggest gains come from combining all four methods above into one repeatable monthly cycle rather than farming inconsistently. Subscribing to four Weekly Diamond Passes, claiming the CoA Daily Supply every day, and purchasing both monthly bundles can realistically generate over 1,200 CoA per month while leaving a Diamond surplus.
Bonus Tip: Additional Ways to Stack More Crystals of Aurora
- Checking the Special Bundle tab in the Diamond recharge section regularly is worthwhile, since it periodically offers a Monthly Epic Bundle worth up to 180 CoA and a Weekly Elite Bundle worth 20 CoA, both stacked on top of the standard monthly supplies.
- Keeping an eye on limited-time events like Lucky Hit adds another CoA channel, since these events often grant a fixed amount of CoA through daily recharge tasks for their entire duration.
- Watching for seasonal cashback events, typically launched at the end of a season, is a passive way to earn bonus CoA simply for Diamond spending already planned.
- Opening Starlight Boxes during special events can sometimes give CoA as an extra bonus, so they are still worth collecting even if you are not on the main subscription.
- Besides following official MLBB channels, monitoring the in-game announcement board is the best way to make sure you don't miss out on these limited-time CoA offers before they disappear. As a rule, most of them are only available for a very short period of time each month.
Conclusion
Farming Crystals of Aurora is more about sticking to a routine and less about making spontaneous purchases. The combination of Weekly Diamond Pass, the CoA Daily Supply, the two monthly bundles, and the Starlight subscription can build a steady CoA stockpile that is strong enough to get a Collector skin without spending Diamonds excessively. Anyone who wants to speed up this routine can use LootBar as a safe and economical means of getting Diamonds, and this MLBB Top Up guide shows more resource-planning tips to help you get to your next Collector skin faster.
