What to Do With Diamonds in Infinity Nikki: 7 Pro Tips to Boost Your Gameplay

If you’ve spent even a week playing Infinity Nikki, you’ve probably accumulated a pile of diamonds from login rewards, story quest clears, and event challenges, and found yourself stuck wondering what to do with diamonds in Infinity Nikki before you waste them on something you’ll regret later. I’ve been playing since the global launch, and I made so many bad spending choices my first month—blowing 3,200 diamonds on random permanent gacha pulls that only gave me duplicate common socks, to be exact—so I’ve got first-hand experience with what works and what doesn’t when it comes to this rare currency. This guide breaks down the best uses, the worst wastes, and custom strategies for every type of player, no matter if you’re free-to-play or drop a little cash on the monthly pass.

Prioritize These High-Return Uses First When Deciding What to Do With Diamonds in Infinity Nikki

When you’re weighing what to do with diamonds in Infinity Nikki, always start with purchases that give you long-term gameplay benefits, not just temporary cosmetic fun. You can earn enough free diamonds for a couple of splurges a month, but your first 10,000 diamonds should go entirely to these high-value options:

  • Limited-time event gacha pulls for exclusive five-star outfits that boost stage scores by 20% or more, and never return to the regular shop after the event ends
  • Unlocking extra wardrobe slots if you collect a lot of custom outfits, as the default 200 slots fill up way faster than you’d expect once you start participating in monthly events
  • Purchasing energy refills during double drop events, so you can farm rare crafting materials twice as fast without waiting for the daily energy reset
  • Buying extra attempts for the Stylist Arena weekly challenges, which give you exclusive ranking rewards you can’t get anywhere else, including rare hair accessories that boost all style scores by 5%
Never spend your first 10,000 diamonds on the regular permanent gacha, by the way. The drop rates for five-star items are 30% lower than limited event banners, and you can get 70% of the permanent gacha’s items from free login and event rewards within your first three months of playing. I learned that the hard way when I spent 8,000 diamonds on permanent pulls early on, only to get a five-star hair I could’ve claimed for free from a login event two weeks later.

Common Diamond Wastes You Should Avoid At All Costs

It’s easy to get tempted by flashy limited-time offers in the shop, but most of them are designed to drain your diamonds faster than you can earn them. If you’re still confused what to do with diamonds in Infinity Nikki, the easiest rule of thumb is to skip any purchase you can get for free elsewhere. Skip the single pull gacha options entirely for starters, because 10-pulls give you a guaranteed four-star or higher item every time, so single throws just waste your currency for no extra bonus. You also don’t want to buy common crafting materials from the diamond shop. You can farm all basic fabric, thread, and button materials for free from story stages in 10 minutes or less, so spending 50 diamonds on a stack of 20 common fabrics is a total waste. I once bought 5 temporary outfit dyes for 200 diamonds total, and they expired before I even got around to using them, so skip all temporary cosmetic items entirely unless they’re given to you for free. Another waste to avoid is purchasing extra story stage retries if you only missed the score threshold by 100 points or less. You can usually adjust your outfit by swapping out one or two accessories to hit the required score, so you don’t need to spend diamonds to retry the same stage over and over.

How to Plan Your Diamond Spending For Long-Term Progression

Part of planning what to do with diamonds in Infinity Nikki long term is knowing the event schedule ahead of time. Official social media accounts usually tease upcoming events two weeks before they launch, so you can plan how much you need to save ahead of time. Set a monthly diamond budget before you start spending, so you don’t blow all your savings on one event and miss out on a better one coming up next month. Most limited events run every 4-6 weeks, so you should aim to save at least 12,000 diamonds for each limited banner if you want to get the full five-star outfit set. You can also track your daily diamond income to make saving easier. Free-to-play players earn around 300 diamonds a day from daily quests, login rewards, and stage challenges, so that adds up to 9,000 diamonds a month before event rewards. If you participate in all monthly events, you can easily hit 15,000 diamonds a month without spending any real cash. Don’t feel pressured to buy every limited outfit set even if you have the diamonds for it, too. Pick the ones that match the style of stages you struggle with the most, so you get the most gameplay benefit from your purchase instead of wasting diamonds on a cute outfit you’ll never use for stage challenges.

Smart Diamond Strategies For Free-to-Play vs Paying Players

The best way to spend your diamonds will change a little depending on if you play for free or spend real money on in-game purchases. For free-to-play players, your top priority should always be limited event gachas that give outfits with stat bonuses for stages you’re stuck on. Skip all cosmetic-only items that don’t give any gameplay benefit, and only spend extra diamonds on energy refills during double drop events for materials you need to craft high-score outfits. You can also earn extra free diamonds by participating in official community contests, so keep an eye on social media for those opportunities. For players who buy the monthly pass, you get double daily diamonds, so you can afford to splurge on one extra cosmetic set a month if you want, but you should still prioritize limited event sets first. Never buy the single diamond top-up packs unless you’re only 100 or so diamonds short of a full gacha set, because the bulk packs give you 3x more diamonds per dollar spent. If you do plan to spend money, stick to the monthly pass and the seasonal pass, which give you the best value for your cash by far. If you’re a casual player who only logs in a couple times a week, you don’t need to stress about saving every diamond. It’s totally fine to spend a few hundred diamonds on a cute outfit you love, as long as you’re not saving up for a limited event set you really want. I keep 20% of my monthly diamond income aside for fun splurges, and it makes the game way more enjoyable than stressing about min-maxing every single purchase.

At the end of the day, figuring out what to do with diamonds in Infinity Nikki is all about balancing what you want with what will help you progress the fastest. You don’t have to follow every rule perfectly, and if there’s a super cute outfit you’ve been eyeing for months, it’s okay to splurge a little as long as you’re not wasting all your savings on stuff you’ll never use. I’ve had way more fun with the game when I stopped stressing about getting every limited set, and started spending a small portion of my diamonds on items that make me happy, while saving the rest for high-value uses. Try out these tips for a month, and you’ll notice you have way more rare outfits and progress way faster through the story than you did before.
